Aoba, who lives a pretty ordinary life, works at the junk shop "Mediocrity." The manager asks him to make a delivery one day, but he finds out that there's nothing at the address he was supposed to deliver it to. It was then that Aoba was consumed by light and he was within a mysterious world.
Don't pick fights if you're just gonna run away!
!لا تفتعلوا شجارات إن كنتم ستهربون وحسب
Wenn ihr wegrennen wollt, 
dann fangt doch gar nicht erst an zu kämpfen.
¡No busquen pelea si luego van a escapar!
¡No busquéis pelea si luego vais a huir!
Si c’était pour s’enfuir,
Se for fugir, não compre brigas!
