Kotarou Mochizuki

As the last surviving members of a unique vampire lineage, this blonde-haired, blue-eyed boy shares a deep bond with his brother, Jirou. Unlike his sibling, he lacks traditional vampire abilities like the "Hide Hand" and remains unaffected by sunlight or water. Despite his small stature and distinct appearance, he possesses an incredible tolerance for pain, surviving brutal impacts unscathed. Interestingly, his mannerisms and speech closely mirror those of Alice, Jirou’s former lover.
