Also known as: 黒沼トレーナー, トレセンの龍
Mihono Bourbon (Umamusume)'s Trainer (Umamusume) from Season 2 of the Umamusume anime.
Appears as a man dressed in 'gangsta rapper' clothes, with sunglasses and hat and an Open Jacket baring his chest. Also has short hair and a Goatee and wears a Necklace. Only his surname is given, as "Kuronuma".
Voiced by Kuroda Takaya of Kiryu Kazuma fame. In fact Kuronuma is a dead ringer for his voice actor, down to having the exact same hairstyle and facial hair. His voice actor is also known to wear the exact same clothes (except with an additional shirt underneath covering his chest) and accessories.
Because of this, Kuronuma is often drawn in fanart channeling the mannerisms of Kiryu Kazuma as a Voice Actor Connection. These examples are often tagged "The Dragon of Tracen" (トレセンの龍) on Japanese websites, as a play on Kazuma's nickname.
