Raniel, the promising wizard and the prospective owner of the most renowned magic tower in the kingdom, gives up his title and leaves to join a heroes’ party led by Kyle, the warrior. Along with the other members, Raniel sets out on adventures to slay the Demon Lord—the evil being who trampled his village long ago. He spends four years defeating the dark forces and grinding half of his life to save his team, only to find out that his effort has been in vain. Kyle suddenly kicks Raniel out of the party one day, claiming that their goals are different. Devastated after getting betrayed by his team, Raniel decides to return to the tower, but things grow worse when he runs into a succubus queen on his way back, gets cursed, and realizes… he has turned into a girl?!
