<b>Tatewaki Kuno</b>, age 17, is the self proclaimed "rising star of the high school fencing world," and has given himself the nickname "Blue Thunder". Upperclassman <b>Kuno</b>, as he prefers to be called, is a well-spoken ladies man. He often quotes Shakespeare or Japanese poems and haiku.

Before <b>Ranma</b> arrived, he was devoted to <b>Akane Tendo</b>, even going so far as to announce to the entire student body that if any of them could beat <b>Akane</b> in combat that they would be allowed to date her. <b>Kuno</b> often said that if Akane could beat him, he'd allow her to go out with him.

<b>Kuno</b> hated <b>Ranma</b> from the moment they met, and couldn't believe he could be engaged to <b>Akane</b>. Later he met <b>Ranma</b> in his female form and instantly fell in love. "The Pigtailed Girl", as he calls female <b>Ranma</b>, and <b>Akane</b> became his reason for living and he has dedicated himself to making the difficult decision of somehow choosing between the two.

<b>Kuno</b> and his sister are some of the few that actually don't understand that male and female <b>Ranma</b> are the same person. <b>Kuno</b>'s hatred for <b>Ranma</b> also stems from the fact that he believes he has somehow romanced the innocent Pigtailed Girl away from him.
