Wolf Game Another: Chapter 2 Investigation

Everyone still gathered in the morgue, Yukinari is dumbfounded as to how Aori died when he was the Wolf. Ritsu quickly points out that there's foam coming from her mouth, and Kou points out a broken red coffee cup nearby. Yukinari recognizes it as the cup he previously drank the poisoned coffee from. These clues lead the group to deduce that Aori was poisoned. Osamu then notices something in Yukinari's pocket. It's revealed that Yukinari is still carrying the poison from before. Combined with the fact that approximately half the liquid is missing, and Ritsu's testimony regarding his previous actions, the group suspects Yukinari is the Wolf. Misaki notably does not comment on the fact that Yukinari offered her coffee as well. While the group is ready to select Yukinari as the Wolf, Merry insists on an investigation anyways.

Yukinari first examines Aori's body, and notices a small stab wound on her abdomen. Satoru notes that the wound is also slightly swollen. It's concluded that this is no normal wound, but its relation to the case remains unclear.

In the library, Yukinari finds a book titled "The Comprehensive Poison Dictionary," and decides to see if there's any information about the poison he attempted to use. He learns that while it is a highly lethal poison, it is not very effective when ingested orally. The dictionary further explains that the poison is effective when it comes into contact with blood, and suggests coating a blade with the poison and stabbing the victim for maximum effect. A photo of a wound inflicted this way is included, a perfect match for Aori's wound. Yukinari concludes that Aori was not made to drink the poison from the coffee cup, but was instead stabbed by a bladed object that had been coated in it. While musing on the case, Yukinari begins to wonder why Aori was discovered in the morgue when she was last seen in the third floor classroom. He realizes it would be too risky and difficult for someone to kill her in the classroom and move her upstairs to the morgue, so she must have gone there herself while she was still alive. He seeks the memo book she was writing in to clarify her final actions.

The memo book can be found in the botanical room on the second floor. Yukinari wonders how it ended up there, if perhaps Aori tried to hide it before she died. The memo book is locked with a passcode, the hint for which is written on the back of the memo book as follows:

> **A:** "There are four personalities inside of me."
>
>

> **A:** "But this memo book is mine, I don't want the others to see it."
>
>

> **B:** "How tempting... Tell me the password too."
>
>

> **C:** "If my memory serves... the password is our important person's birthday, isn't it...?"
>
>

> **B:** "For real?!"
>
>

> **D:** "That's right...! When I first discovered the password... I realized you need to input the birthday as is, don't flip the date and month or anything like that...!"
>
>

> **B:** "Really...? Well, you're a liar so I don't know that I believe that."
>
>

> **D:** "Huh~?! I say that everyone besides me is a liar...!"
>
>

> **B:** "No, no... C is just forgetful that's all..."
>
>

> **A:** "In any case..."
>
>

> **A:** "I've already changed the password..."
>
>

> **A:** "You won't find out anyways so... I'll give you a hint, it's the day of my favorite sweet..."
>

Yukinari goes back to the classroom to check Aori's backpack for clues about the password. Within, he finds an old letter. It's handwritten, and appears to be written by a child. The letter is addressed to someone on their birthday, and the writer calls the addressee their "everything." The letter also discusses how the writer was saved by the addressee and expresses a hope that they'll meet again one day. The letter is dated December 25th, and signed by Aori.

Inputting the password 2512, Yukinari realizes that it was a logic puzzle, in which the statements given were used to reason which personalities were lying (A and D were the liars, while C and B told the truth). The memo book opens. Inside are Aori's impressions of everyone:
