Beelzebub III, Kaiser de Emperana
Summary
Beelzebub III, the Great Demon King, is characterized by his erratic and forgetful nature. Tasked with the destruction of humanity, he initially dispatches his youngest son, Beelzebub IV, to the human realm to carry out this mission. However, he later changes his mind and decides to send his eldest son instead, completely forgetting that he had already sent the youngest. Once his servants remind him of the previous order, he rectifies the situation by sending his firstborn, En, to join his younger brother.
