Description
Zett Takajō serves as a mysterious guide for protagonists throughout multiple Devil Children narratives. In Devil Children Red/Black Book, he appears as a young boy in Harajuku, directing Setsuna Kai and Mirai Kaname to the demon world Expanse. He offers recurring advice during their journeys, informing Setsuna of his brother Nagahisa's abduction and revealing to Mirai that her father resides in the Expanse. His interventions include aiding escapes, such as helping Setsuna evade Central Land's guards, and clarifying critical plot information like the nature of devil children and the significance of Messiah Horns/Eyes.
After Setsuna and Mirai defeat the demon Zebul in the bonus dungeon Deep Hole, Zett discloses his true identity as Zebul. Zebul is a powerful demon sealed underground alongside his brothers Belphegor (Phegor) and Berith; collectively, they are the "Baal brothers," remnants of a fragmented deity. Zett's human form is a non-combatant avatar ("thought form") created while Zebul's true body remains imprisoned, contrasting with his combat-capable manga portrayal.
In Devil Children White Book, Zett guides Masaki Kuzuha after Takaharu Ougi's sister, Shou, is cursed. He instructs Masaki to find a cure in the Expanse, accessed via a portal at a construction site, reinforcing his role as a catalyst for protagonists' journeys.
In DemiKids: Light & Dark (localized Devil Children Light/Dark Book), he is adapted as "Hawk," an S-Rank BattleNet opponent. Hawk's profile identifies him as the human form of a Deep Hole demon. After gifting the protagonist two demons, he reverts to his true Zebul form, battling alongside his brothers Veritto and Phegor and random demons. Defeating him multiple times yields specific demon rewards.
Additional lore from series planners notes Zett attended Harajuku National Elementary School—a government facility monitoring supernatural beings—alongside other demons in human guise. His avatar could eat and speak but not fight. The spell summoning his true form references "Holy Children," a term for the first offspring of Adam and the creator deity Hoshigami.
His overarching motive across media involves manipulating events to prevent apocalyptic outcomes like Armageddon, positioning him as a behind-the-scenes orchestrator.
