Sake Nishimori has just had a fatal accident. Luckily for him though, death isn't the end of his story; it's only the beginning. Sake finds himself at the whims of a maniacal astral being called 'The House' and is forced into entering a competition with other reincarnated souls against his will. Fortunately, there's hope for Sake yet. Being the last contestant to enter the game, Sake is given a special class designed specifically for him; The Sovereign Class.

Can Sake prevent the destruction of the magical fantasy world of Azealia while learning the rules of a universe he knows nothing about and the strange aspects of his unique class? Or will he by wiped out by monsters, demon lords, and the other competitors before he can stop the world from ending?
