Description
Taito Kurogane is a 16-year-old student at Miyasaka High, recognizable by his blue hair and red eyes, typically dressed in his school uniform with a student council armband. Once a karate prodigy, an injury shattered his confidence, leaving him believing he was ordinary until a near-fatal incident triggered the return of sealed memories. These memories revealed a childhood contract with the vampire Saitohimea, granting him conditional immortality: he resurrects after death but permanently dies if killed seven times within 15 minutes. His first death occurred saving a classmate from a truck, reuniting him with Himea.

Kind, naive, yet strong-willed, Taito displays a childish protectiveness towards Himea. His central drive is shielding her from supernatural threats, particularly the Tenma, leading him to join the student council alongside Himea and its president, Gekkou Kurenai. Taito and Gekkou share a competitive, sibling-like rivalry built on trust.

His abilities are defined by cost:
* **Resurrective Immortality**: Each death consumes one "life," resetting after 15 minutes unless all seven are lost. A tattoo manifests on his palm per death, fading as lives deplete.
* **Forbidden Fire**: Himea granted him this lethal blue-flame attack, but each activation costs one life.
* **Dark Rabbit Mode**: An alternate personality stemming from military experiments allows him to "reject" existences by erasing their foundational "words," effectively deleting targets from reality. This mode also downloads prophecies into his mind, but overuse causes cerebral meltdowns, each costing one life.

Taito's relationship with Himea is foundational; he cherishes her as his childhood love and vows never to leave her isolated. This devotion creates tension with his childhood friend Haruka Shigure, who harbors romantic feelings. This dynamic intensifies when Haruka is revealed to have a supernatural connection to the Tenma prophecy, intertwining their fates.

To strengthen his protective power, Taito makes deals with entities like Edeluca, exchanging "the most important thing to him" for strength – mirroring Himea's earlier sacrifice of her own power to resurrect him. In battle, he frequently exploits his immortality, enduring grievous wounds like decapitation or disintegration, confident he will resurrect unless his seven-life limit within 15 minutes is breached.
