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. Even still, she claims she is much calmer compared to her childhood. She has also described herself as "not very good at thinking" and appears quite gullible and impulsive, using her emotions over logic.
