Seventeen years old, the eldest child and only son of the wealthy Kunou family. An arrogant young man who often pompously quotes poetry, he professed to love Akane Tendo, but seems completely unconcerned about her feelings in the matter. Not particularly bright, but his ego is unassailable. He dislikes his sister and prefers to ignore her whenever possible, but will attend her gymnastics matches for the sake of appearances, which are very important to him.
Kunou’s sport and passion is Kendo, and he often carries a bokken (wooden kendo sword), and wears a gi and hakama as casual wear. His skill, speed and strength are well above human capability, and he is capable of such feats as casually slicing through tree trunks, smashing walls, and even cracking stone with the air pressure from his strikes alone. Despite this, he is notably inferior to his sister in combat, and no match at all for the likes of Ranma.
