宇宙英雄物語

Godou Juuji is a student at Heisei High School in Tokyo when his grandfather's starship passes to him. The ship takes him out of the ordinary solar system into the Shinnaru Taiyoukei, a parallel one where magic works and planets are held by feudal houses. Sakumi Shiihara is the reason he keeps going: the search for her pulls him across those worlds, into other people's wars and up against the powers that run them.
