Defrott, an ancient S-class vampire with the deceptive visage of a youth, wields centuries-old power beneath a polished exterior. His piercing blue slitted eyes flicker crimson when provoked, contrasting with soft curls and immaculate attire—a creme-colored coat, crisp white pants, and sturdy brown boots. Though radiating detached intellect, his obsession with beauty anchors him to human artistry, from haunting theater productions to the lyrical cadence of literature.

Once a celebrated child performer at Tokyo’s Imperial Theater, his immortality eroded his ties to humanity until fate intertwined him with Misaki Nakajima, a gifted actress whose mortal injury during a performance spurred him to grant her vampiric rebirth. Her desperate wish—to enact *Salome* for her fiancé, Maeda—briefly thawed his emotional detachment. Yet her deliberate demise under sunlight shattered him, unleashing centuries-suppressed recklessness.

Journalist Aoi Shirase later rekindled his fragile connection to the living. Bonding over theatrical passion and investigative intrigue, their rapport deepened despite her initial ignorance of his true nature and her uncanny resemblance to Misaki. Defrott’s influence spirals through pivotal events: transforming Maeda into a vampire amid the Great Kanto Earthquake’s chaos to honor Misaki, only to witness Maeda’s agonizing struggle with immortality.

A habitual weaver of classical play quotes into conversation, his speech mirrors a life steeped in performance, framing the narrative’s meditation on eternity and fleeting human bonds. As the story’s epilogue voice, he dissects loss and existence through allusions to Blakean verse, his journey crescendoing from spectral observer to reluctant architect of fates. Oldest among his kind, he straddles secrecy and redemption, his alliances and enmities etching tragedy and resolve into the tapestry of immortal and mortal lives alike.
