Tenko is a boisterous and generally cheerful person. She wears her emotions on her sleeve and 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 and anti-romance stance, she feels an intense hatred towards boys, to the point of referring to them as "degenerate males"
