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.
What do you mean, "Erp"? 
That's so mean, Aoba-chan!
!ما الذي تعنيه بتلك الهمهمة؟ هذا تصرّف لئيم حقّاً يا (آوبا)-سان
Was meinst du mit „Urgs“?
Das ist so gemein von dir, Aoba!
¿Qué fue ese ruido? 
 ¡Eres muy cruel, Aoba-chan!
¿Qué ha sido ese ruido? ¡Eres 
muy cruel, Aoba-chan!
Comment ça, « argh » ?
Como assim "er"? Que crueldade, Aoba!
