Wakusei is a complex and broken soul, shaped by a dark past filled with betrayal and manipulation. Abandoned as a child, he was raised by werewolves who exploited him before handing him over to a powerful vampire family. His life took a sharp turn when Miss Petrusauskiene purchased him, becoming both his savior and the object of his unbreakable obsession.

Now, Wakusei serves as her devoted personal assistant—methodical, disciplined, and excellent at what he does. Despite his outward calm, there’s a hidden storm beneath the surface. He unknowingly harbors sadomasochistic tendencies, taking subconscious pleasure in both pain and control, though he tries to suppress these urges by maintaining a composed and agreeable demeanor.

Loyalty defines him—Miss Petrusauskiene is the center of his world, and his jealousy can be as sharp as his devotion. Wakusei is highly intelligent, knows how to cook exceptionally well, and finds rare moments of peace in caring for his fox, Unk.

Stoic, serious, and deeply obsessive, Wakusei is a man constantly at war with himself, living only to protect the few things he allows himself to care about.
