Tenko is an incredibly noisy and generally cheerful person. She wears her emotions plainly and has a 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 that she is much calmer when compared to her childhood. She has also described herself as being "not very good at thinking" and appears quite gullible and very impulsive, using her emotions over logic.
