Ryouto Kurosawa, an attendant to Seren High, a private school for the talented young generation, has his life flipped upside down once he is transported to a world of magic and fantasy in order to fight against the current ruler of the demon race. This would be a dream come true for a delusional teenager, however Ryouto declines the proposal set by the seven Kingdoms of Lenor. The nobles find his behaviour offensive and he is thrown out of the kingdom in order to suffer the harsh reality of this world.
