Tatsuya Katsuragi

About

Tatsuya is Yuuki's childhood friend, and the CEO of a successful corporation. He used to be physically weak as a child, but gained strength after training in the Sawamura dojo. Twelve years later, he still holds resentment towards Yuuki, whom he believes betrayed him by refusing to run away together. After they meet again, Tatsuya blackmails Yuuki into participating as a "steed" in the fights at Kishidou Club in exchange for medical care for Yuuki's father.
