"The antidote is in that room. Find it. Good luck."
— Zero, after telling C-Team that they've been poisoned

The Infirmary is an escape room. It is searched by Carlos, Junpei, and Akane.


The CT scanner, examination table, and variety of other equipment offer the ability to perform basic medical checks.


Carlos, Junpei and Akane wake up in the infirmary, but discover they aren't locked in. They are still forced to search the room, however, when Zero tells them that "the six" of them are poisoned and the antidote is in the room.

Decision Game


The 8 antidotes, but only one is correct.

There are 8 antidotes, but only one of them is correct.

A - B - C - D - E - F - G - H

Carlos licks E, F, G, H.

Junpei licks C, D, G, H.

Akane licks B, D, F, H.

  • Since no one licks A, if none of them react, the antidote must be A.
  • Since everyone licks H, if all of them react, the antidote must be H.

Because of the above, the player only has to focus on:

B - C - D - E - F - G

If a team member has no reaction, all four samples they licked are worthless.

If a team member has a reaction, one of the four they licked is the correct antidote.

  • If only one team member has a reaction, they licked something that the other two didn't. What they licked that the other members didn't lick is the antidote.
  • If two team members have a reaction, they licked something that the other one didn't. Look at B - C - D - E - F - G and remove the four that the one with no reaction licked. Then see what the two other licked with a reaction have in common - there can only be one in common. The one in common is the antidote.

For the lazy, look at the second last line in the log while selecting the antidote:

  • If no one has a reaction ("No one felt anything" in the log), it's A.
  • If only Akane has a reaction ("Only Akane felt numb" in the log), it's B.
  • If only Junpei has a reaction ("Only Junpei felt numb" in the log), it's C.
  • If only Carlos doesn't have a reaction ("Only I didn't feel anything" in the log), it's D.
  • If only Carlos has a reaction ("Only I felt numb"), it's E.
  • If only Junpei doesn't have a reaction ("Only Junpei didn't feel anything" in the log), it's F.
  • If only Akane doesn't have a reaction ("Only Akane didn't feel anything" in the log), it's G.
  • If all three have a reaction ("All three of us felt it" in the log), it's H.


  • The background music has a sound effect of a heartbeat, suiting this room.
