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.)

Touhoushinki Arc
Oga is destroying armed mercenaries and local thugs. As they pleaded for mercy Oga fought them alone, and with an off-screen tilt, he was shown to have battled them rigorously. Many were unconscious, and although it seemed the series was unfolding in an event-themed fashion, it was shown that it was really Oga's retelling of what transpired to Furuichi Takayuki. His story continued and he explained how a large man came floating upstream (the local riverside) and he eventually cracked open, revealing a small baby. Furuichi is shocked by Oga's lack of story-telling abilities (although the retelling was revealed to be true), and the two continue in loud voices. Be'el is completely focused on the conversation at hand and he remained quiet for the most part of their conversation. Oga continues his rant on the Be'el situation and reveals that he must take care of the demon baby, because the child is so attached to Oga's raw abilities. Hilda is mentioned and referenced during his conversation and Furuichi is quite taken by her.



The next day, Oga takes Be'el to school with him. Furuichi wonders out loud why he would go to that much trouble for the kid. The story continues with Hajime Kanzaki's mercenary forces coming in contact with Oga. Furuichi is worried about Oga's status among the students at Ishiyama High. The students are convinced Oga is the father of Be'el and are shocked by their self-perscribed qualifications. Oga becomes aware of Hajime Kanzaki's status as among the four Tohoshinki. Being the somewhat sadistic and irresponsible teen that he is, Oga seeks out Kansaki in an attempt to force Be'el on him. His logic was that "strong men" were most appealing to Be'el, and that the most malicious of characters would satisfy his needs. When the two meet, the discussion takes a dangerous turn as Kanzaki sends one of his own men flying with a direct attack (after annoying him). Be'el was touched on the head by kanzaki, Oga realized that he was rejected as Be'el did not react, and in retaliation, sent Kanzaki flying. Leaving Kanzaki's men completely shocked, Oga leaves the area feeling rather disappointed.



The next step for Oga was handling the other menacing forces of Ishiyama. The second step was Tatsuya Himekawa, another thug who uses his money and influences to gain dominance. He was approached by Kanzaki and easily took care of him ,and afterwards, Himekawa went to handle Oga directly. He kidnapped Furuichi and Hilda (both were seen with severe burns). Oga was flooded from head to toe in his room, and was immediately disgruntled. He went to the warehouse where Himekawa had the two held. He blasted through his thugs (reinforcement), and made his way to Himekawa. However, Himekawa turned out to be a more competent opponent than Kanzaki. His weapon was a stung rod and with fluid movements he had Oga on the ropes momentarily. However, Oga simply stated that the shock he received from the rod was nothing compared to Be'el's tantrums. With Be'el's power, Oga was able to send Himekawa flying. Himekawa was later shown, feeling somewhat bitter, in the hospital along with Kanzaki.



After defeating two of the Tohoshinki, Oga claimed somewhat of a celebrity status among the students. Although he did not seem any more out of the ordinary, he was commented on by many of the juveniles that pollute the school. Oga takes Be'el to the park as what he calls his park debut. There he meets a young girl wearing glasses and a stroller. Oga attempts to become friendlier as he does not want to be thought of as cruel or uncaring.

He sits near the girl and strikes up a conversation, the girl was later revealed to be one of the four Tohoshinki, the leader of the feminine group Aoi Kunieda.

Although she wears a disguise at the park, perhaps as a means to protect her reputation, Oga is completely oblivious when the two square off. He is unable to identify her although it appears as though Be'el was able to make the distinction less apparent.

Aoi was the one looking for Oga as he was said to be "breaking a difficult and dangerous balance", an allusion to his complete destruction of both Kanzaki and Himekawa. Aoi quickly proves herself to be a competent fighter, with rapid speed and a clear understanding of martial arts. She wields a wooden sword, and although not an actual sword, she yields the same results as though it were metallic, slicing the window barrings and their reinforcements.

Oga is quick to the challenge and avoids fighting her. Aoi is shocked to see that Oga is carrying a child, and as such is thrown completely off guard by him asking her to become Be'els mother.

Although it was merely his means to ditch the child, Aoi took this as more of an invitation to become his partner, and as such, she became infatuated with him even developing a crush along the way.

Oga's troubled road through Ishiyama continued when the last and final Tohoshinki was revealed. Oga left his house after Be'el showed signs of their severed bonds. He was launched out of his window after showing a hurt and emotional Hilda his theory of leaving Be'el. Although he was only referring to the electric shocks, Hilda smashed him through the window and ordered him to leave. While walking through the park, Oga was attacked by Tojo's top fighter in an alley-way. Their fight was only a means of testing Oga's power, and as such, the subbordiante left without any signs of anger or tiredness, a statistic Oga picked up on well. A confused Oga wondered about the the relation the two shared. The subordinate answered calmly and then exited the alley-way, missing his next hit on Oga (which was sure to be a devastating blow).

When Oga awoke the next morning, he noticed baby Be'el was missing and Hilda was once again absent. Furuichi pondered this and spoke openly on why Oga was taking the situation to lightly. A jubilant Oga was cut short on his celebrations, and was forced to go search for the two by his estranged sister. Oga went to look by the river-bed as that was where he first found Be'el. Tojo and his subbordinate were there, and Be'el was also present, this time riding on the back of Tojo. A fight ensued, and with that Oga began to notice issues with Be'el. HIs glazed eyes were unfocused and the attachment to Tojo was almost abnormal. Oga concluded that the power he had was enough to draw Be'el towards him. Oga demanded to know how he found Be'el in the first place. Tojo answered honestly that he found Be'el roaming the streets. He then took a few jabs at Oga's terrible parenting skills. Be'el was set to be the prize of the fight, and Oga was quickly beat to the point where he succumed to serious injuries. Oga took the upper hand, catching him of guard until he noticed the zebub spell's contract on Tojo's arm. Tojo sent Oga flying and afterwards took Be'el and left the scene. Oga returned home, bitter and angry, to find Hilda and a ghost like creature in his stairway.

The ghost-like creature turned out to be the demon doctor, a physician who Hilda called to assist with the examination of Oga and Be'el. Oga immediately struck a nerve with the two commenting on both their looks assuming they were low-class demons. He wondered why the demon doctor was so animated. The doctor continued his examination of Oga (with a few minor interruption in the form of Lamia his assistant). The doctor determined that the severing of the bond was because Oga was not powerful enough to keep up with Be'el. A bruised Oga relinquished his role as surrogate father momentarily, in an attempt to regain his strength. Oga wondered aloud whether Be'el was better off with Tojo. He was snapped back into reality by Hilda and his fighting spirit returned.

While taking a shower, he was interrupted by Kanzaki's subordinate. He is told to follow him to the scene of a brutal battle between Kanzaki, Hajime, and Tojo. Tojo defeated Kanzaki and Hajime with help from his own subordinate, a bespeckled man with apparent power. Kanzaki and Hajime are forced to work with Oga in an attempt to defeat Tojo. Oga does not take to this smoothly however, and with blatant disregard, he tries to turn down the offer. However, he sees reason and the three make their way to the school.

Unfortunately the trio is ambushed by local gangs, a tactic used cleverly by Tojo. Kanzaki and Hajime fend off two opponents each and were dumbfounded to notice Oga handling the rest on his own. Unfortunately, the thugs continue to emerge, and the trio find themselves growing tired. Aoi jumps in and fends them off one by one protecting the three from further harm. Her female group is also present and Aoi tells Oga to continue on ahead and find Tojo.



Oga runs into the school looking for Tojo. On his way, he notices fireworks being set off, and he continues on his way towards the fireworks' location. When the two meet, Tojo reveals he figured out that Oga's the father of Be'el. He inquires to return it, stating that perhaps a fight over him would be more suitable. Oga states his relation to Be'el being more caring and out of friendship, then going to say that it is up to Be'el to decide. The once warped Be'el regains his composure and glazed look, and he creates a demon circle with estranged markings. A force-field is created and the electric prevents anyone from entering. Oga penetrates the sheild, doing more damage to himself, and with a cocky smile gives Be'el the same smile he gave him during their training sessions. The two bonded once more and a "Revival" of their core was created.

Oga now deals with Toujo. The fight between the two was full of complacent blows and rigorious hits. Oga had Tojo on the ropes momentarily and intended to land a strong hit to his midsection. However Tojo repelled the attack and made a blitz behind Oga with a killing blow in mind. Oga dodges and sidesteps him and returns to Be'el and Furuichi's location (Furuichi being there on his own accord). Be'el feeds Oga some power, and the contracting Zebub spell is generated. Oga tells Be'el to stay away from the fight, this includes his help with any zebub spell or magic of any kind. Be'el realizes this, and he sinks his power back to himself. Oga continues his fight and takes a blow from Tojo on purpose, as a means to get bind him and engage a suplex-type move, crushing Tojo.

An exhausted Oga limbers back to Be'el stating his win and the two lock eyes. Oga then notices that his arm deformed during the fight. The magic built up and released explictly through his arm. The blast destroyed the school and the trials at Ishiyama High concluded with Oga reighning victory over the Tohoshinki.
