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.
He didn't remember anything
 from the time he was missing.
لكنه لم يتذكّر أيّ  شيء مما حدث له وقت اختفائه
Anscheinend weiß er nicht mehr,
 was passierte, als er verschwand.
pero no recuerda nada del momento 
en el que estuvo desaparecido.
pero no recuerda nada del tiempo 
en el que estuvo desaparecido.
mais ils ne se souvenaient pas
Ele não se lembrava de nada do que 
aconteceu enquanto esteve sumido.
