|Japanese name:||播磨 拳児|
|Nickname:||Hige, Harima Hario|
Harima struggles often to confess to Tenma, though he knows she has absolutely no feelings for him and may even dislike him. Every time Harima finds the courage to tell Tenma his true feelings, something happens which prevents him from succeeding. Harima also must deal with situations involving his classmate Eri, unaware of the fact that she does not know whether to like or dislike him. He gets extremely jealous seeing Karasuma and Tenma together, but his attempts to put a stop to that usually end up bringing them closer. Ironically, Harima admires Nijō jō(二条丈) the mangaka, which is Karasuma's pen name. To date, Tenma has yet to hear his confession properly. He also works as a mangaka, having Yakumo as his assistant, creating another source of misunderstandings, as it took a long time for Tenma to realize that their relationship is only professional, at least by Harima's side.
