Summary
Yahiro Saiga, born on July 7, is a carefree young man who harbors a sinister side. He has known Kei and Akira since childhood, notably once defeating Kei in a game of tag by locking the door to the roof to prevent Kei from winning. Yahiro attends Kokusengakuen and serves as the heir to the Saiga Financial Group, an entity that holds a higher status than the Takishima group. In his youth, Yahiro struggled to make friends because his attitude consistently made others cry rather than smile or laugh. He remained isolated until he met Sakura, after whom he decided to open up and form friendships.
