Tsubasa Hayakawa

Tsubasa Hayakawa leads a double life—by day, a warm and welcoming café staff member at Café du Vane, known for his signature owl-shaped latte art that charms every customer who walks through the door. Beneath this gentle exterior, however, lies a far deeper truth: he is a member of the Butlers, an ancient guardian clan with over a thousand years of history. Once bound to protagonist Takuma Jinguji as a close companion, a twist of fate across time transformed their bond into a century-spanning rivalry. As the keeper of secrets tied to their bloodline, Tsubasa stands at the very heart of the story's mysteries.
