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 finding the pink-haired girl from the murder scene sitting next to him in class; someone keeps snooping around his house.

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.
