When a human appears in the Demon Realm and declares his intention to join the Calamity Lord Academy to become the next tyrant of Creation and obtain the Edict, no one takes him seriously. Though some question how he managed to cross the Realm Barrier that isolates all the Realms from each other, most assume that it was through luck. After all, Humans are the weakest of all the Realm Races. How could a human possibly ever become the next Calamity Lord?

However, Ain is not an ordinary human, yet only a pair of financially ruined goblins believe in his chances to obtain the title (and save them from crippling debt).
