Description
Kōya Urabe is a supporting character in Ace of Diamond Act II Second Season. He is a third-year pitcher and the ace for Norikane Academy, a school that appears as an opponent in the West Tokyo summer tournament. Urabe's background is marked by an unusual and determined path. He originally enrolled at the elite Teito High School, known for its strong baseball program, but he left the baseball team after only two weeks. He then transferred to Norikane Academy during his second year. Because of the transfer, he was subject to a one-year playing ban, which he endured before finally being able to compete in official games. His first appearance on the mound for Norikane was against Seidou High School, the series' main team, in the West Tokyo tournament.

Urabe's personality is defined by a strong, resilient mindset. He is portrayed as someone with the resolve to start over from scratch in pursuit of his ideal baseball environment. He does not cling to the prestige of a name like Teito; instead, he seeks a place where he can truly play and develop. This shows a pragmatic and self-aware character who values personal growth and opportunity over reputation. His motivation is rooted in a desire to prove himself and to compete at his best, having sacrificed a year of eligibility to transfer.

In the story, Urabe serves as an obstacle for Seidou, representing the challenge of an unknown but determined ace. His role is to demonstrate that even schools without a storied history can field skilled and motivated players. Key relationships include his teammates at Norikane, with whom he builds a cohesive unit after transferring, and his direct confrontations with Seidou's batters, particularly as a pitcher facing the powerful Seidou lineup.

Development-wise, Urabe's journey is a condensed arc of a player who makes a difficult choice to leave a powerhouse for a fresh start, pays the price with a year without games, and then returns stronger and more focused. His notable abilities center on his pitching. He is the ace of his team, and his strength lies in his mental fortitude and refined technique. He is not described as having overwhelming velocity, but rather as a pitcher who commands the game with precision and a strong will. His experience of leaving Teito and his subsequent year of training have honed his concentration and determination, making him a reliable leader on the mound for Norikane.
