Tōta Konoe, a 14-year-old artificial human crafted from the merged DNA of Negi Springfield and Asuna Kagurazaka, bears a genetic legacy that grants extraordinary abilities while barring conventional magic use due to opposing light and dark magical energies. Raised by the ageless vampire mage Yukihime—formerly Evangeline A.K. McDowell—after his parents’ purported demise in a car accident, his life fractures when an assassination attempt forces Yukihime to convert him into an immortal vampire to preserve his existence. His vampiric immortality accelerates healing and negates fatal wounds, though severed limbs remain irreplaceable if intact. Tōta commands a gravity blade modulating weight exponentially and harnesses Magia Erebea, absorbing magic to amplify physical and mystical prowess. Inheriting Asuna’s Anti-Magic, he nullifies external spells. Subsequent discoveries reveal his blood crystallizes into magical constructs, enabling clone generation and bodily regeneration. As UQ Holder’s seventh member, Tōta confronts immortal hunters, rival factions, and existential crises like the Lifemaker. A 43-year temporal leap follows his fusion with a World Tree to stabilize Earth’s fractured space elevator, erasing his memories and prompting a fragmented rediscovery of his past. Initially plagued by doubts over his artificial origins and perceived role as Negi’s substitute, he gradually embraces self-worth through mentorship and alliances. Relationships define his journey: his bond with Kuroumaru Tokisaka, a genderless crow demi-human, evolves from camaraderie to romance after Kuroumaru’s physical feminization. Connections with Karin Yuuki and Kirie Sakurame mirror his awakening to romantic and sexual complexities despite early innocence. Driven to safeguard allies and ascend the cosmic pillar Amanomihashira, Tōta epitomizes an All-Loving Hero, instinctively aiding allies and strangers alike. Combat ingenuity inherited from Negi fuels mastery of techniques like Shundo and tactical adaptability. Vulnerabilities surface through anti-magic disrupting regeneration and dependence on external magic for advanced states such as Raiten Taisou II. His narrative weaves identity, legacy, and immortality’s toll, climaxing in clashes against Fate Averruncus and the Lifemaker. Transitioning from impulsive youth to resolute guardian, Tōta carves a destiny untethered from Negi’s shadow, balancing personal ambition with duty to shield those he cherishes.
