TV Special
Description
Tatsumi Oga anchors all official narratives as a 16-year-old first-year at Ishiyama High, an institution famed for its delinquents. Born August 31 and standing 179 cm tall, he wields sharp black eyes beneath brown hair, his muscular frame clad in a worn shirt, brown leather jacket, and jeans. Intense emotions twist his features into a demonic grimace. When activating Super Milk Time, his hair shifts to green and he adopts the pacifier of Beelzebub IV—the demon infant he’s magically contracted to raise.

Initially embodying a ruthless delinquent archetype, Oga relishes inflicting agonizing pain and brutal punishments, traits aligning with the demon realm’s requirements for Beelzebub’s caregiver: strength, toughness, selfishness, and indifference. Yet beneath this exterior simmers unexpected loyalty. He engineers his friend Takayuki Furuichi’s return during summer break to stave off loneliness and once attacked Miki preemptively to shield him from future violence. Oga enforces a chivalric code, refusing to harm female opponents like Aoi Kunieda or Pillar adversaries, and absorbs critical advice—such as Saotome’s five-minute limit for Super Milk Time.

Childhood forged his core beliefs: Santa Claus faith shattered at age three triggered a near-death vision of his grandfather. His bond with Furuichi ignited in fifth grade when Furuichi demanded to stand beside him in battle—not behind—reflecting Oga’s creed that true allies need no protection. Their partnership weathered brawls like the Red Tail gang clash and the coded-language mystery of the "First Pokopen Incident."

The contract manifests as the Zebul Spell, a demonic seal on Oga’s right hand that swells with malice or proximity to Beelzebub. It unlocks escalating powers: the building-shattering Zebul Blast, precision-tagged explosives via Zebul Emblem, and Super Milk Time—syncing with Beelzebub to amplify strength and magic. Black Techs refine this synchronization for coordinated assaults. Zebul Finisher unleashes cataclysm by merging hundreds of emblems. Peak power arrives via "Super Saiyan Switch," channeling Beelzebub’s full energy for pseudo-flight, lightning control, and island-razing force, demonstrated against fused entities like Fuji and Satan. Weaknesses include proximity dependence (initially 15 meters) and vulnerability if Beelzebub is wounded.

Early combat philosophy saw him seeking stronger hosts for Beelzebub, like the Tōhōshinki. But facing MK5 assassins, demon contractors, and dimensional threats, Oga embraced guardianship. He defended Ishiyama during its annihilation by Beelzebub’s energy, allied with former rivals, and journeyed to the demon world. Returning with a second mysterious infant, he cemented his evolution from reluctant caretaker to unwavering protector.
