Sora no Otoshimono: Tokeijikake no Angeloid

The movie centers around a sweet, gentle girl named Hiyori Kazane, who has harbored a massive crush on the protagonist, Tomoki Sakurai, since they were young. She finally builds up the courage to get closer to him by joining the New World Discovery Club. For the first half of the movie, we get a lot of the classic, chaotic romantic-comedy antics the series is known for as Hiyori tries to win Tomoki's affection.
