Mumei is confined in a classroom full of traps. 
Trying to escape along with his comrades, they set off the traps and are sent to another world.
A strange old man was waiting there. 
Mumei's classmates exhaust themselves without skills going up against an enemy that gets stronger the more he drinks.
A sense of foreboding reaches the bewildered Mumei.
As long as I have a minute, I'm in no trouble.

Kein Problem in einer Minute.
Con un minuto será suficiente.
Con un minuto será suficiente.
Une minute est bien suffisante.
Un minuto è più che sufficiente.
Não há problema, mesmo com um minuto.
