She's a boisterous and generally cheerful person. She wears her emotions on her sleeve, has the habit of yelling out in a loud voice to show her fighting spirit. She suffers from overactivity and anger issues and directs her energy into her Neo Aikido. Due to past experiences and her master's irresponsible teachings she feels an intense hatred towards boys, referring to them as "degenerate males". Tenko likes other girls much more, protective of them all but also gets very shy around them too.
