Mysterious Disappearances

The curse of Tsukuyomis Water of Youth hasnt finished with Sumireko yet. Meanwhile, Adashinos younger sister, Oto, picks up on the presence of a Curiosity at the school she attends. Sumireko poses as Otos friend in order to infiltrate the school.

The cuckoo known as Adashino cries in the deserted Midori Bookshop once more. Sumireko intends to spend her day off writing. As shes admiring the sakura outside her window, she gets a text from Adashino asking her to look after Oto for two or three days.

Shizuku is looking for Tomoko, who disappeared on a rainy night a year ago. Based on Tomokos final video call, Adashino has a guess about the Curiosity, but he has a few concerns. Oto wants to help Shizuku, so she begins her own search.

When Sumireko was young, her inability to express herself often led to trouble with her friends. One day, she ran from them and ended up at a strange bookshop. The woman there recommended a book and offered a suggestion to help her speak more easily.

Yorumun begins hijacking popular streamers videos, rapidly escalating the commotion around her. Adashino tries to save Nodoka, but Nodoka refuses his help, defending Yorumun instead. Then Uname brings a woman in a wheelchair to meet them.

Adashino has vanished from Sumirekos sight. The Cat Sovereign appears at the station just as Oto is returning from visiting Uname. Adashino intervenes, but speaking with the Cat Sovereign makes Oto remember something shes forgotten for ten years.
