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.
If you mess with him, he'll break your jaw.
إذا قمت بمواجهته فسيكسر فكّك
Wenn ihr euch mit dem hier anlegt,
 bekommt ihr es mit mir zu tun.
Si se meten con él, les romperá la quijada.
Si os metéis con él, os partirá la mandíbula.
Si vous le collez,
Se mexer com ele, 
quebro a sua mandíbula.
