Tatsumi Oga

"Oga" redirects here. For other uses, see Oga (disambiguation). Tatsumi Oga (男鹿 辰巳) is the main protagonist in the Beelzebub series.

Oga is first introduced as a strong fighter, beating up some fellow class mates and then making them bow down to him because they had attacked him in his sleep. He was picked to become Beelzebub's father because he possessed the qualities of the ideal parent for the future Demon King: strong, arrogant, and thinks-nothing-of-fellow-man. In addition to the aformentioned attributes, Oga also seems to take pleasure in tormenting others. Oga and Beelzebub cannot be separated by more than 15 meters or else it may result in instant death for Oga, according to Hilda [2] (as of chapter 38, the distance has increased with 8 centimeters).

Appearance
Oga is usually seen sporting a grotesque grin and his demonic features are visibly shown when he is either angry or disturbed. He possesses brown hair and dark eyes, he is rather muscular with a wide-spread build, and his attire usually consists of a worn-out shirt and plain pants (usually jeans). He has been shown on a few ocassions to be wearing either sweatpants, and on one ocassion, has even been shown wearing his pijamas (ironically very detailed with pinstripes going down the side). When Oga attempts to smile, he is usually seen with a demonic, evil grin. This speaks to his lack of social skills (due to his inhibition in a juvenile delinquent high school).

When fighting, Oga appears to have a different look. Aside from his rare comedic entrances (usually as a relief from an intense situation), he is usually very calm and actually quite aware. His eyes are alert and he seems in control of his emotions. Be'el does not transfer this emotion however, and is usually shown in a maintained angry look.

Personality
Initially, Oga was nothing more than a crude and uncaring delinquent whose only friend seemed to be Furuichi. While he wouldn't start fights, he would take deliberate pleasure in inflicting the most pain possible when facing his opponents, reguarly resulting to cruel and unusual methods of punishment for his defeated enemies. It is because of these qualites that he was initially chosen to become Beel's parent. The qualites apparently needed were, "Strong, Tough, Self-centered, and cares nothing for his fellow man" as "that kind of shitty bastard is the best."

As the series continues, it should be noted that the trials Oga has faced and the new friends he has gained has altered his personality somewhat. For ex; When the Horsemen called out Ishiyama to meet them on the rooftop, Oga first came alone. But later on Himekawa, Kunieda, and Natsumi soon arrived and Oga smiled knowing that they have his back. Though he retains his love for his cruelty, he is now much more calm and easier to be around then he was at the start of the series.

In his own twisted way, he seems to care for the people that are close to him. When Furuichi was gone during for summer vacation and leaving Oga alone, he called Alaindelon to transport Furuichi back home just so he can hang out with him. Or beating up and embarassing Miki infront of their school back in middle school. Only because it was to protect him from Kiriya Reiji because he knew that both Miki and Kiriya would move to Nara at the same time, and if Miki was involved, then Kiriya would've attacked Miki in Nara where Oga wouldn't be there to protect him.

Oga doesn't seem to have any sense of appeal nor opposition against girls, unlike Furuichi who is easily seduced and will not hesitate to pick up girls. However, he does also has a sense of chivalry, as said by Hilda, Oga will not fight or harm a woman. This was proven true when he only dodges during his fight with Aoi, and more recently when fighting the female pillars he held back when he realize he was about to hit a girl. The only times he actually hits a girl was a sparring match with Aoi to determine if they were capable of learning black techs and knocking out Yuchelle by destroying her weapon.

As much as Oga hates it, he tends to listens to lectures very well. For ex. When Oga was telling Teimou about Baby Beel's demon praying dance, Kunieda quickly takes him to the side and lectures him about being careful who to talk to about demons and only talk about them who are involved. After that, Oga never told anyone besides (excluding demons) Furichi, Kunieda, Kunieda's Grandpa, and Saotome. Or when Saotome was lecturing Oga about using Super Milk Time for 5 minutes max. When Oga uses Super Milk Time, he only fought for 5 minutes after using a huge blast that knocked him into unconsciousness.

As the series progresses, he learns how to put his pride aside and knows when to follow orders. (For example, in chapter 126, when Saotome said that the Ishiyama students were going to need training with him, all of the delinquents didn't want to train with him because they thought he was an old geezer and was weaker than them and it will take their pride away. But Oga stepped up and said let's go train, instead of being arrogant and keeping his pride, he put it to the side and went to get stronger.)
