Tomodachi Game

After the hard-earned funds for their expensive high school class trip are stolen, Yuichi and his four best friends are kidnapped by Manabu, a character from a creepy late-night anime show. The mischievous Manabu challenges the students to mind games that the five must decipher and outwit in order to win back their trip funds, uncover the thief, and pay off a huge and mysterious debt.

Yuichi and friends reach the end of Kokkuri-san, uncovering dimensions of trickery in the Tomodachi Game that they hadn't imagined. When they move on to a second game, a socially destructive version of sugoroku, the group struggles to maintain balance as personal secrets are revealed and trust is stretched to its absolute limit.

Dark secrets are exposed as the second game, Bad-Mouth Sugoroku, continues. Yutori is devastated when a traumatic episode from her past is revealed, leading her to suspect the only other person who knew—Shiho. As debts increase, the five friends are driven further apart. With no one else to turn to, Yutori clings to Yuichi for help, and Yuichi pledges his support.

Responsible for the theft of the class funds, the application to play Tomodachi Game, and the exposure of all kinds of dirty secrets in Bad-Mouth Sugoroku, Tenji now tries to alienate Shiho from the others so he can have her all to himself. But while Tenji is busy sweet-talking Shiho and planning his next move, a "special chance" appears for Shiho that might change the direction of the game.

Shibe reels from the accusation that he has "actually killed a person." Despite protesting that he never did such a thing, he loses the audience's confidence and is thrust into first place. Meanwhile, Tenji finds himself in a distressing situation after realizing Yuichi is the one who wrote the card. Yuichi then makes the shocking announcement that he knows who the traitor is

Backed into a corner by Yuichi's plan, Tenji is forced to confess that he applied to play Tomodachi Game. Yuichi spells out the traps he set to smoke out the traitor and reveals that he had been manipulating the game from the start. The second game then reaches a breathtakingly unexpected conclusion.

After clearing Bad-Mouth Sugoroku, Yuichi and Tenji find themselves trapped in a dark cave for three days. During their isolation, Tenji makes the shocking revelation that he had already experienced a Tomodachi Game in the past. Meanwhile, a team of new opponents lies in wait outside, anxious to challenge the two partners to a grueling third game.

The third game, Friendly Hide-and-Seek, begins. Rival Group K, bolstered by an apparent 'genius' strategist, proceeds with a numerical advantage. Yuichi confidently tells Tenji to "just trust me and wait," but then doesn't return for days...

Yuichi, who hasn't left the starting point in the two days since the game began, suddenly announces his desire to switch to Group K. The Group K members, puzzled by Yuichi's intention to abandon his hiding teammate, ask their Captain to decide whether or not to let Yuichi in. Meanwhile, Tenji, who has stayed in hiding and trusted Yuichi all along, is finally reaching his physical breaking point.

Finally able to shake his Group K guards, Yuichi succeeds in delivering food to Tenji. After being pushed off the cliff by Yuichi, Maria slowly gets closer to her saviors Hyakutaro and Chisato, but that too is a trap set by Yuichi to destroy the friendships in Group K.

With "true genius" Kei controlling things, Group K succeeds in finding Tenji. Facing the "worst thing that could have happened," Tenji makes a phone call to a person. While the two groups struggled to outwit each other, Shiho, Shibe, and Yutori, who had been temporarily released for the third game, returned to school only to be met with cold stares from their classmates.

With the circumstances around Shiho's disappearance and Shibe's arrest still unclear, a mysterious person declares a new game that demands Yuichi's participation and threatens Yutori's life. When Yuichi rushes to save Yutori, he becomes trapped in the cruelest game. The two friends must decide how much pain they can endure to protect each other and the special edition "Weak Win Game" begins.
