Haruka returns to her present time-space and invites Karasu to live with her after he unplugged his pipeline. Though little did she expect she would get involved with Yuu's relationship problems with his mother.
Haruka deals with the concept of forgetting, as her memories of her grandmother are disappearing, and an old friend she had in Tokyo is unable to recognize her.
Noein tries to manipulate Haruka into bending her will into his desires by showing her, through Ai, Isami, and Miho, the future they would have had if it remained untouched.
