Oga, Tatsumi

男鹿辰巳

Tatsumi Oga serves as the main protagonist of the Beelzebub series. He is first introduced as a formidable fighter who beats up several classmates and forces them to bow to him after they attacked him while he was sleeping. He was chosen to become Beelzebub's parent because he possessed the qualities of the ideal parent for the future Demon Lord: he is strong, arrogant, and shows no regard for his fellow man. In addition to these attributes, Oga also seems to take pleasure in tormenting others. As the series progresses, it should be noted that the trials Oga has faced and the new friends he has gained have altered his personality somewhat. For example, when the Rokkisei called out Ishiyama to meet them on the rooftop, he initially came alone. However, later on, when Himekawa, Kunieda, and Natsume soon arrived, Oga smiled, knowing that they had his back, though he retains his love for cruelty.
