Team Spica's trainer is currently unnamed. He is often nicknamed "Okino T" by the Japanese fanbase, as a reference to his seiyuu, Okino Kouji. The Trainer also shares some resemblance with his seiyuu.
He is sloppy at his job and often teases Hana in their rivalry. His careless behavior often results in him getting bullied by his own pupils. Instead of properly instructing his pupils with racing strategies, he trusts them and allow them to run according to their own desire. However, he can be a little strict on their training. Despite his 'unique' and impulsive ways of managing his team, things do go well. He also can be off-putting upon first meet, he tends to feel horse girl's thigh muscles which lead to misunderstandings.
In an official model sheet, his name is stated as 西崎リョウ (Nishizaki Ryou) though this is never referenced in other published materials.
