Ken puts very little efforts in his studies, which grants him the nickname, alongside two of his classmate, who share his lack of academic abilities, "3 Idiots of D-Class". He is always seen to sleep in class, and also once refused to join Suzune Horikita's study group for the sakes of his grade.

He is known for having hot headed temper as he is quick to get angry when people do what he deems pointless as well as when someone insults him being ready for a fight, showing how easily provoked he can be.
