- "I couldn't... save Clover... My sister died... because of me... Perhaps this will... begin to... atone for that... Perhaps in... the afterlife... She can... forgive me."
- — Light, avenging his sister's death in the Safe / Zero Lost Ending
Light Field (ライト・フィールド Raito Fīrudo), also known by his codename Snake, is one of the nine players in the Nonary Game. His bracelet number is 2. Light is Clover's older brother. At the start of the game, Junpei gave him the nickname "Prince" due to his regal appearance. He was kidnapped by Zero at the same time as Clover and placed in a room similar to the 3rd class cabin with her.
Light is blind and almost always keeps his blue eyes closed. His chin-length hair, parted in the center, seems to be a silver-like color and his skin is very pale.
His left arm is actually prosthetic, but has the appearance of life-like, realistic skin - perhaps a precursor to Artificial Biological Tissue (ABT), like Sigma Klim. His left arm and left hands are seen in different positions, such as clenched fist and open palm, implying that he also has cybernetic nerves and a bionic arm (given the 2027 technology). This is supported by him clinging onto pants with his left hand, as well as the fact that his hand and arm refuses to release with such strength, even after being kicked.
He wore a fancy blue jacket with yellow piping over a white dress shirt and burgundy tie, gray slacks and brown shoes. Like the other players, he wears a bracelet on his left wrist.
When he was abducted and placed in the coffin in the room with Door 9, he wore a Free the Soul robe used in Dashiell Gordain and his successors' version of the Nonary Game and his normal clothes were placed onto Nagisa Nijisaki.
In 2018, when Light was a 15-year-old teenager, he had peek-a-bang styled hair covering his right eye. He wore a navy jacket over a dark hoodie, blue jeans, and brown boots.
- "Snake is the wisest. Despite his blindness, or perhaps because of it, he has the insight to see through various truths. He is level-headed, calm, rational, and logical. He is also very knowledgeable about a variety of topics and well-versed in various genres. He loves his little sister Clover, and wouldn’t hesitate to sacrifice himself if it would save her. Who would have thought we would find him like that...?"
- — Kotaro Uchikoshi 
Light has a princely demeanor. He is level-headed, calm, rational, logical and mature. Despite the dangerous situations he found himself in, he usually remained calm, but when he was angered, he would become very aggressive.
Light is based on the "Investigator" Enneagram of Personality. Its basic desire is mastery and understanding, much like how Light acts as a source of wisdom and knowledge. Light is very intelligent and wise. He is also very knowledgeable about a variety of topics and well-versed in various genres, such as culture and religion. He is an unending source of information, but tends to only reveal it when there is no other option. At times, he came off as a bit arrogant. He was interested in the guitar and harp, implying he loves music and being creative.
He loved Clover with a passion and tries to protect her, and would do anything for her, even dying to avenge her death. He kept the truth about the Nonary Game a secret in order to protect Clover and only opened up once he knew it was safe to do so.
Despite his blindness, or perhaps because of it, he has the insight to see through various truths.
Snake: Intelligence often hides itself in darkness. Have you ever thought about the pages of a book? Each page only sees...what, maybe 2 or 3 minutes of light before the reader is on to the next? They spend the rest of their lives locked in darkness. Rather like myself... Oh, don't get me wrong. I'm not complaining. Not at all. I live in the darkness, yes. But that has gifted me with the ability to catch the truths others might miss.
He also has a strong sense of hearing and touch.
He hates being talked down to or underestimated, and he claims he could win in a physical fight.
Junpei: When Clover fell on the big staircase a little while ago, you were at her side immediately. So that was...hm.
Snake: Yes. I could hear it happening. In fact, I can run quite fast--certainly as fast as you. And should someone attempt to start a fight with me, I am quite confident that I could defeat them. You don't believe me, do you? Care to give me a try? I must warn you, you'll no doubt regret it.
Junpei: Snake, are you gonna be all right? I mean, the stairs...
Snake: Please, do not do yourself the embarrassment of underestimating me. I would be unlikely to trip even if I were running backwards.
During his childhood, Light lost both his eyesight and his left arm in a car accident and had his arm replaced with a prosthesis. It was the only way to save him, according to Clover. When Junpei investigates the glass panels in the casino, Light gets very sad. It is possible that during his car accident, glass cut his eyes, causing his blindness. It is unknown if Clover was also involved in this accident.
According to the 999 novelization (which is non-canon to the game), instead of a car accident, Snake lost his eyesight by falling off a cliff while trying to help Clover. He apparently used to like playing the guitar, but couldn't after the accident. He also learned braille.
As he was growing up, he became very close to his younger sister Clover, who helped him cope with his blindness, and she acted as Light's eyes. They essentially became inseparable.
In 2018, Light was kidnapped by Cradle Pharmaceutical thugs because both he and Clover passed a Ganzfeld Experiment test at one of Cradle's hospitals for the purpose of the First Nonary Game. In the First Nonary Game, Light claims he was abducted while he was looking for four-leaf clovers outside for Clover's birthday and and he also claims he had managed to find exactly nine of them. (However, it's possible that this was just a white lie in order to cheer everyone up since in the novelization, the clovers are mere accessories, not actual real clovers.) Clover was also kidnapped as a transmitter for the Nonary Game and was placed in Building Q in Nevada, while Light was placed in the Gigantic as a receiver.
During his time on the Gigantic, Light distributed the four-leaf clovers to the other players on the Gigantic, when they began to argue and break down in the large hospital room. He explained how they must make it out alive for their siblings, and tells them that he has a sister who is special to him and that it was her birthday that day and that he got them for her birthday. He told them that the leaves on the clover represented Hope, Faith, Love and Luck respectively, and that if they remembered those words, they would be able to get through any obstacle.
The group made it to the incinerator. Light's group was rescued by a detective, Seven, using a rope of bedsheets. However, a girl, Akane Kurashiki, ran back to get her missing doll. Light, Seven, and Aoi Kurashiki also returned, only to make it to the locked incinerator door. Whether or not she was incinerated is undetermined.
Nine Hours, Nine Persons, Nine Doors
Nine years later, Light and Clover were kidnapped for the Second Nonary Game by Zero. They presumably woke up in a room similar to the 3rd class cabin together and managed to escape it. Light and the other players (besides June) ran down the central staircase only to encounter Junpei and two numbered doors Door 4 and Door 5.
After he helped the other players investigate the ship and choose codenames, the 9th Man took Clover hostage with his knife. The 9th Man entered Door 5 with Clover's and Ace's help but he gruesomely died, affecting everyone except Light.
Santa insisted that they were wasting time and should proceed through the numbered doors, stating that he won't "mess up" like the 9th Man did. Light laughed this off and explained that his death was caused by disobeying Zero's rules. The 9th Man had entered by himself, when the minimum requirement was 3 people. Light revealed that Zero had given Light the "gift" of knowledge on the Nonary Game and the bracelets the nine players wore. On a message in braille, it told him how to take off the bracelets and the function of the REDs and DEADs in the game and that there were bombs in their intestines.
If Junpei chose Door 4
Reassured by the note, the players continued through the doors; Santa, Junpei, June, and Lotus went through Door 4, and Ace, Light, Clover, and Seven went through Door 5. Light and his group solved the puzzles in the 1st class cabin and Casino and ended up in the Large hospital room with the other four players.
If Junpei chose Door 5
Light entered Door 5 with Junpei and Seven and they investigate the 1st class cabin and casino.
Snake (Light) goes missing
In the large hospital room, three numbered doors were located, Door 3, Door 7, and Door 8. None of them could be opened however, as the bottom part of the REDs were mysteriously gone, so they split up to find the parts in the hallway with all the rooms.
While investigating a small room in one of the hallways on C Deck, Light was knocked out with soporific gas by Santa. Light was unable to tell who his assailant was due to being blind. His clothes were switched with Nagisa Nijisaki and Light was placed in a coffin in the Chapel (when this occurred is unknown, but it is possible this was done by Crash Keys members after the players went into the doors in the hospital room). Noticing that he did not come to the large hospital room, the other players conducted a search for him, with no results. They decided to go on without him, causing Clover to suffer from depression.
Later on, Nijisaki's body was found in the shower room, wearing Snake's clothes. Since the body was destroyed, the players thought that it was Snake, amplifying Clover's dread and distrust of the other players.
Safe / Zero Lost Ending
In the shower room, Junpei realized that the body there was not Light's since it had a bone broken in its left arm, and he remembered Clover telling him in the laboratory that Light's was prosthetic.
Unfortunately, soon after this, Clover was found dead. A note in Clover's hand provided a hint for the combination of the safe in the 1st class cabin. After opening it, a note inside revealed that Light had been an unwilling participant of a Nonary Game in 2018. Junpei then realized who killed Clover: Ace. After Junpei interrogated him, Ace held Lotus hostage. Junpei and Seven followed Ace and Lotus after leaving Santa and June in the large hospital room.
In the chapel, Junpei and Seven unlocked Light's coffin using the safe combination that Junpei had found earlier using the "sinister hand" tip from Clover's body. They asked him about the recent information that they had learned about from Ace's confession, but he refused to give them answers, falsely claiming that he didn't remember or know most of the facts. They did not tell Light that Ace killed Clover, as they feared that he would be completely devastated by her death.
Eventually Light, Seven, and Junpei opened the big Door 9, using Seven, Junpei, and the 0 bracelet, which Seven took from Clover's body. They figured out that the 0 bracelet's true value was six, but didn't dwell on why it was not a zero. They suddenly heard a rush of water, a cruel reminder that their time was nearly up. Seven suggested they got moving, and he and Junpei asked Light how he was going to get through the door without scanning his bracelet. Light crushed his prosthetic arm in order to remove the bracelet and placed it in the coffin.
Eventually they arrived at the incinerator, in which Ace told Light that he killed Clover and that he enjoyed it. Ace taunted Light to attack him and Light threw a fit of rage at Ace and tried to attack him, but Ace shot at him with the revolver from the cargo room. Lotus was freed from Ace's grasp but Ace then pointed his revolver at Junpei, saying that he had to hand over Lotus or he would kill him, Seven, and Lotus. Just as Ace was about to shoot Junpei, Light got back on his feet and walked towards Ace threatening to kill him. Ace wasted all his remaining bullets on Light but that still didn't stop him. The reason for this is his tenacity. His love for his sister Clover and unfaltering will to avenge her murder made him a super-man.
He was able to grab Ace and hold him down. He said he would burn with Ace in order to avenge his sister's death, to atone for his failure to protect her. Ace begged Light to let him go, promising to treat his injuries with his Cradle Pharmaceutical hospitals, but he refused Ace's offer. Eventually, the PA announced that the incinerator would activate in one minute. Seven and Lotus left the incinerator, but Junpei refused to let Light die. He ran towards Light, but Seven stopped him from getting burned by punching Junpei in the stomach and carrying him out of the incinerator at the last second. Junpei watched through the window of the incinerator as Ace and Light burned to death.
On this route, in the chart room, Clover mentions that she is thinking about her brother and why someone would want to kill him. Angrily, Clover says that the murderers will pay for it and asks Junpei who could've done it. They go through the possibilities, finding that at least two other people had to have activated the RED with Light. The only possible combination is Santa and Seven working together. Junpei suggests that 3 or 4 people could've worked together, but the only possible combination for that is Ace, Santa, Seven, and Lotus working together, which Clover deems highly unlikely, as Seven and/or Ace could've killed her in the shower room, but they didn't. They settle on the high likelihood that Santa and Seven killed him. Junpei asks for a motive, and Clover is about to give one, but Ace walks into the room. Ace has to ask him something and Junpei walks to the wheelhouse with him.
Later, in the Captain's Quarters, Clover, Junpei and Ace find Musashidou's corpse on the ground and a 0 bracelet on his left arm. Ace, disgusted by the corpse, goes back into the communications office. Junpei uses the time to try to talk to Clover. He asks if she thinks the dead captain is Zero, and she shakes her head no. She still insists that Zero is one of the players. Junpei points out that the clues are too obvious for the man to be Zero, and that the real Zero is mocking them. Clover puts it off as a sick joke and they decide to closely examine his body. The bracelet falls off of his left wrist and Junpei says that the man had an easier death than Light or the 9th Man. He continues by saying that some of Light's bones had pierced his skin, and that there was a broken one sticking out of his left arm. Clover inquires about the corpse's left arm and to Junpei's surprise, she thanks him and gives him a hug. In between her tears, she says that the body in the shower room is not Light's, as his left arm is prosthetic. Clover pulls out the bookmark and graciously thanks him for giving it to her and tells him that he was right about Snake still being alive. Junpei mentions that she should thank Santa for the bookmark, as he gave it to him.
Clover breaks away from Junpei, and paces around the room, deep in thought. She says that the fact that Santa had given him the bookmark was good news, as only the test subjects of the First Nonary Game knew about it. Junpei asks her to calm down and tell him everything that she knows. She starts by saying that telepathy was being tested on the ship, and that they played the Nonary Game during it. Nine people had been placed on board the ship, and another 9 over in Nevada. Junpei asks what the game has to do with telepathy, and she explains that it is easier to transmit information through the field when a person is exposed to epiphany and danger. She says that the game was a life-or-death situation, and that one girl had actually died. She was in Light's group, on board the Gigantic. Clover is about to reveal her name, when Ace suddenly walks in. Ace asks Junpei to help him look through the communications room, and a disappointed Junpei goes to help him.
After opening the exit in the quarters, the group escapes and Clover takes the 0 bracelet and the sinister hand tip before she leaves the room, believing that they will be useful. She tells Junpei about the note, but fails to mention the bracelet. They travel back to the central staircase and meet up with the other team along the way. June happily mentions that her group had found Door 9. The players excitedly shove themselves into the elevator and take the flight down to E Deck. Seven leads the players to a small room, which they cram into. The group finds that they are in a chapel in see that there are two 9 doors in the room. Everyone is excited about escaping, but Clover cuts in and says that not everyone would be able to proceed. She does some calculations on Junpei's notebook and finds that if 4 people escape, 3 stay behind, and if 3 escape, 4 stay behind.
The room is quiet until Seven breaks the silence. He volunteers to stay behind, but is met with disapproval from the others on the idea. Santa speaks up on the issue and says that he doesn't want to leave Seven behind "alone". Santa quickly takes June hostage and reveals that he has a golden revolver, taken from the cargo room. He drags June to the big 9 door and demands that Lotus and Ace come with them. He then shoots the floorboards, to show that he is not screwing around with them. Clover tries to stop Santa, but he threatens to kill her if she doesn't follow his orders. From some persuading by Junpei, with Clover saying there was something she had to do, presumably look for Snake, they reluctantly follow Santa through the door.
Clover, Junpei, and Seven are left alone in the chapel, certain that they are going to die. They sit around in silence, when suddenly, a knocking sound is heard, coming from a coffin sitting on the altar. Junpei and Seven walk up to it, trying to pry it open. Junpei sees that there is an electronic lock on it and that he would need a passcode to open it. Suddenly, Junpei hears a voice in his head, telling him "Truth had gone, truth had gone, truth had gone. Ah, now truth is asleep in the darkness of the sinister hand." Junpei starts to think about what it might mean and looks down at the buttons on his bracelet. He presses the buttons in this order: right-left-right-left-right-left. Instantaneously, the bracelet flashes the numbers 1-4-3-8-3-4-2-1. He punches in the numbers on the lock, and it opens.
Junpei opened his coffin, surprised that Light was inside. Clover hugged Light in a heartwarming embrace, although Light was confused on why she was crying. After his sister calmed down, Light found out that Santa had led Ace, June, and Lotus through one of the Door 9s and insisted that they should hurry up to catch up to them. He stated that he was unconscious since the group was searching for the missing hardware for the RED. When Junpei scanned the 0 bracelet, Light stated that June's bracelet was probably flipped because the 0 bracelet's (or rather, the letter O bracelet's) true value is 6. He is also able to determine Santa's bracelet's real value, which he thinks is 0.
In the Library, Junpei confronts Light for information about the First Nonary Game. Light explains that he kept quiet in order to protect Clover, thinking that her bracelet had a detonator inside it; the braille letter from Zero claimed that if Light spoke about it, she would die. He explains about Cradle Pharmaceutical and Morphogenetic Field Theory. He explains that he witnessed Akane Kurashiki's death 9 years ago. They then find a passage to the Study, where Junpei finds out that Ace is the CEO of Cradle Pharmaceutical. Seven then regains his memory after seeing Ace's picture and tells Junpei and Clover what happened on the Gigantic. He asks Light if he is working with Zero. He says that he had nothing to do with Zero, but he recognized Ace from his voice, saying that his voice was the devil.
The four of them arrive at the incinerator after leaving the Study. Light watched as Junpei got Ace to admit his true identity as Gentarou Hongou and the circumstances of Nijisaki's, Kubota's and Musashidou's deaths. He escaped the facility with Junpei and the others after Junpei helped Akane survive in the past by completing a puzzle, leading to the outside. They then leave in a SUV provided for them and pick up a hitchhiker: Alice.
Clover picks the woman up, who reveals that her name is Alice. Alice takes Clover and the other players to a SOIS (Special Office of Internal Security) facility for questioning about what happened during the Second Nonary Game. After the session, all of the players were released, except for Ace.
Clover and Light went on to live average lives. However, because Clover and Light were already kidnapped twice, their worried and concerned mother hired bodyguards. Clover and Light didn't like it so they ran away and lived on their own in an apartment, but they kept in contact with their mother via social media to let her know they were safe, of course.
Clover worked in a cafe and Light started to play the harp, compose "new-agey" music, and wrote a book. Light's popular harp playing supported them financially a bit. Sometimes, he would play at venues like coffee houses where his fans would come, listen to the music and cry because of how beautiful it was. Some of Light's fans formed a fan club where they would meet, recite his book and play his songs. Although it sounds a bit cult-y, Clover claims these fans would do this on their own and Light had nothing to do with it.
At some point, he told Clover about neostigmine, a drug known as a cholinesterase inhibitor and a type of carbamate compound which acts as a reversible acetylcholinesterase inhibitor, exciting the parasympathetic nerve. This allows it to counteract tubocurarine. This knowledge later helps Clover, Sigma and the other players in the Nonary Game: Ambidex Edition.
One day, Alice asked the two to join the Special Office of Internal Security. At first, Clover and Light were hesitant to join SOIS because they wanted to relax and escape from the past, but after a phone call from Seven, they gave in and decided to help Alice. There, they met all of the other children who were kidnapped to play the First Nonary Game except Akane and Aoi, whose whereabouts are unknown. They were trained to develop their abilities to resonate their thoughts through the morphogenetic field. They were classified as Espers for their abilities. Clover and Light had a particularly strong resonance with each other and the two were partnered with Alice.
He also participated in Clover's first infiltration mission by having Clover transmit information to him. Unfortunately, her mission was a failure and Clover was kidnapped.
Virtue's Last Reward
During the game, Clover repeatedly tries to communicate with Light through the morphogenetic field but has no luck, as revealed in the Clover-END. During this end, Clover reveals Light's relation with SOIS and his job as a harpist. It is unknown if he survived the Radical-6 outbreak in the game's timeline.
He is also mentioned in the Secret Archives.
Zero Time Dilemma
Light is never mentioned once in the entire game, despite that question 2 of the VLR Answers said the third game would reveal what happened to him during the events of Virtue's Last Reward.
Because the events of the game never "technically" occur, he is presumably still a harpist and may be recruited by Crash Keys to prevent the upcoming threat of all of humanity dying alongside Clover.
He is also symbolized by a crown on the slot machine in the Rec Room.
His name Light is ironic because he is unable to see light, as he is blind.
Light and Clover were both given the last name "Field" during a VLR Q and A session. This would make sense as Mr./Mrs. Field would name their children with pun-like names with a sense of humor, and Clover seems to have inherited her parent(s) quirky qualities. In addition, both Light and Clover Field can use the morphogenetic "field".
The codename Snake comes from the term "snake eyes", which refers to the result of rolling a sum of 2 with a pair of dice. It also is a reference to how, in the Safe Ending, he refused to let Ace go and gripped him until he died, just likes snakes do.
His Japanese alias Nirusu (ニルス), as stated in the official artwork, comes from the first name of a physicist, the Danish physicist Niels Bohr (ぼくのことはニルスと呼んでもらいたい。敬愛する物理学者のファーストネームなんだ。- "I'd like to be called 'Nirusu'. That's because it's the first name of a physicist I respect.") His Japanese alias contains the word ni (ニ), which means "two" in Japanese.
- "That's 9 of us, then. All of the cards are in hand."
- "I would appreciate it if you would call me Snake. My bracelet number is (2). Since Ace has chosen cards, then I choose dice--"snake-eyes", clearly. Which is particularly relevant, given that I am blind."
- "Hehe...hehe... Ahahahahahahaha! Oh, my apologies... You were just... So very confident! I couldn't help myself."
- "That is correct. A gold star for you, Junpei."
- "Well, I know a great many things, but... Yes."
- "Do you intend to kill me? I assume you haven't forgotten the door only remains open for 9 seconds, have you?"
- "Junpei, how long to you intend to abuse that chair? I suggest you finish soon. Otherwise, I may be forced to teach you a lesson in physical pain."
- "Junpei, I cannot help but notice your interest in the bed. Perhaps you are hoping we will spend time on it, together..."
- "Ah yes. You know, that sort of thing is known as a "vanity". Were you aware of that, Junpei? Of course, "vanity" also refers to self-love, conceit, and narcissism. As such, you could say that every day, when a woman looks into one of these... She is staring at her own conceit and narcissism. Doesn't that strike you as terribly sad?"
- "A vase? Well, I suppose that might be useful for bludgeoning Seven over the head."
- "So, you've filled the vase with water, have you? I assume you intend to dump it onto Seven's head? Hmm... Not a bad idea. Very well. I would appreciate it if you would put this plan into action post-haste."
- "I am shocked and appalled that guessing at random has not yielded better results."
- "Junpei, we must leave before Seven goes insane!"
- "Would you, ah, like me to leave you two alone together?"
- "A woman, something with a pointy tip, and...an upside-down butt...? It sounds like a rather sensual shadow-play."
- "I'll kill you... I'll kill you... Hurgh... This is... it, Ace... We're going to... burn to death... together." (grabbing Ace in the incinerator)
- "Heavens no. There are many factors--length, girth, lubrication or lack of... It's an exciting and rapidly growing field."
- "If you can't think of anything clever, please don't strain yourself. You might hurt something."
- It is implied that Clover and Light don't wear underwear because it's a "special custom in their household."
- A plot contrivance, done in order for Clover to not be with her brother when he disappears, is that the players didn't question someone blind searching the rooms for the missing RED. Clover also left him alone, despite that some of the rooms could also be booby trapped, and despite that she was upset by them separating at Door 4/5.
- Some fans have theorized that Light would suffocate to death in the coffin in certain endings. While this possible, it is also possible that a Crash Keys member would free Light since the experiment already failed. However, Crash Keys would have a lot of explaining to do, especially in the endings where Clover is dead or implied to be dead.
- He is the only character who can remove his bracelet freely without having to use aluminum foil, escaping, or dying. He calls it the literal "last trick up his sleeve".
- Snake, along with June, are the only two characters in 999 to never have used any kind of profanity within the game, although he says "what the hell" in the chapel during the Safe Ending in the DS version. In The Nonary Games, his "what the hell" is removed.
- Snake only accompanies Junpei through odd numbered doors. He also goes through the least amount of numbered doors with Junpei.
- In the 1st class cabin, Junpei may examine a light and say out loud "Well, at least we've got light", and Snake says "What!?" Then in the casino, Junpei may examine another light and say out loud "Huh... a light". Snake then tenses up after. This foreshadows Snake's real name.
- Light is the only character to have 2 outfits in 999, those being his suit and the Free the Soul robes.
- In the character popularity polls, Snake ranks #4 in Japan and #1 in the United States, trailing only his sister in overall popularity.
- In the 999 novelization, Light hands out four leaf clover accessories instead of actual clovers to the other children on board the Gigantic.
- In the pantry in VLR, if Sigma exits the ice cube sliding puzzle 4 times on Easy Mode, a pissed off Clover mentions if her brother were here, he would solve the puzzle faster than Sigma and that they would already be out of this room. This could also be seen as Clover dissing Sigma as she could mean that even someone who is blind would complete the puzzle faster than him.
