He is voiced by Natsuki Hanae who also voiced Taichi Yagami from Digimon Adventure tri..
Asahi has short brown hair and brown eyes.
Kuromine Asahi is shy but always kind to others when it comes to doing something he can't even do. He is also willing to embarass himself to protect others. This is usually seen through his perverted actions (accidentaly caused), thus gaining him the nickname "Eromine Asahi".
He discovers that his current crush, Yōko, is a vampire when he finds her unfurling her wings after school. As a result, he is forced to keep her secret, lest she have to drop out of both school and his life.
Throughout the series, he comes to learn secrets about his other classmates and finds that the people around him are not who they seem to be. Often forced to play the straight man in increasingly absurd situations, Asahi often acts as the narrator through his inner monologues. He is also susceptible to projectile nosebleeds when confronted with perverse situations, earning the nickname "Eromine" from Yōko. As the series progresses, Asahi and Yōko begin dating.
- Asahi has a younger sister named Mei, though she is barely mentioned in the story until much later on.
