Reclusive Takumi suffers from a delusion about Seira, his favourite anime character, and gets into real-life trouble when he witnesses a murder.

Takumi fears he is losing his mind after he finds the pink-haired girl from the murder scene sitting next to him in class.

Takumi has a flashback to his childhood and remembers a time when an angry wish seemed to come true, shedding light on his reclusive existence.

Takumi begins to search for a weapon of his own, but his frantic quest is complicated by an unwanted visit from the police.

Takumi learns the police are investigating the school. Ayase tells Takumi that the swords come from a parallel dimension, as delusions in the real world.

As Yua continues to pursue him, Takumi tries to tell Rimi about the possibility that he can make delusions become real. Rimi doesn't believe him, but then the sky turns white and the ground begins to shake.
