Gabriel, a vampire and Noelle’s older brother, belongs to a supernatural family that complicates Yuusuke Kamoshita’s life. His striking appearance features tanned skin, purple shoulder-length hair, and piercing blue-green eyes accentuated by pointed ears, prominent fangs, and playful cheek curls. Bat-shaped tattoos crawl across his arms and back, while his eclectic wardrobe includes gloves, sunglasses, and goggles perched uselessly atop his head.

Known for his mischievous humor, Gabriel relentlessly needles Yuusuke, dubbing him “son-in-law” as part of the family’s chaotic rapport. Though a vampire, he subsists mainly on tomato juice—a vegetarian quirk that sometimes fails to curb his cravings. His severe allergy to cats fuels clashes with Miruru, a feline-antagonistic Dispel agent turned maid after their faction’s downfall.

Despite initial hostility, Gabriel gradually tolerates Miruru’s presence, adapting grudgingly to the household’s shifting dynamics. While protective of his siblings, his older-brother instincts often blur into lighthearted teasing, balancing familial loyalty with a flair for playful antagonism. His story remains rooted in domestic chaos and situational comedy, his interactions weaving through the family’s eccentricities without delving into a standalone past or external lore.
