In a quiet little town surrounded by the mountains, Tomoki Sakurai lives a peaceful life with his somewhat Megaton Karate Chop-prone childhood friend waking him up in the morning. That, and the recurring dream of a girl in the sky. At the same time, school eccentric Eishirou Sugata has been witnessing an unidentified thing moving above the Earth, with nobody able to figure it out. Through a series of circumstances, Tomoki ends up being the only one around when the thing falls to Earth near his hometown. In it is a girl in skimpy clothing with angel wings, calling herself an Angeloid. Her name is Ikaros. Things just got a lot more interesting...whether our hero likes it or not.Sora no Otoshimono is a 77-chapter manga created by Suu Mikazuki (who previously wrote Watashi No Messiah Sama) that spawned (currently) two anime seasons and two movie releases.
