Kaien Cross

As the eccentric yet profound Headmaster of Cross Academy, this former vampire hunter shares a deep paternal bond with both Yuuki and Zero, having raised them as his adoptive children. Driven by a vision of lasting harmony between humans and vampires, he founded the Night Class to foster coexistence between the two species. While his outward personality often appears whimsical, he possesses a hidden, serious intensity shaped by his legendary past battling the undead.
