Shota, a bug fanatic, takes on the responsibility of raising a rhinoceros beetle named Moriking. His sister, Shoko, wants nothing to do with it. Things take a turn for the crazy when Moriking emerges from his pupa as an attractive man with a horn and crown on his head. Thanks to Shota’s love and care, Moriking has super evolved and is actually a candidate in the contest to become the king of the forest! And Shoko is having none of it!
