Sora no Otoshimono Movie: Tokeijikake no Angeloid

Hiyori Kazane has quietly watched Tomoki Sakurai from the edges of his chaotic life, nursing feelings she has never managed to express. Hoping to close the distance between them, she joins the New World Discovery Club and finally begins sharing the strange, ridiculous days Tomoki spends with Ikaros, Nymph, Astraea, and the others.

Her happiness is fragile. Hiyori is connected to Synapse in a way Tomoki does not understand, and a sudden tragedy exposes how unstable the boundary between his world and the Angeloids' realm truly is. When memories of Hiyori begin to disappear and she is transformed into a weapon against the people she wanted to be close to, Tomoki refuses to accept a future in which she is simply erased.
