The Ultimate Aikido Master. Tenko is an incredibly noisy 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. She has also described herself as being "not very good at thinking" and appears quite gullible and very impulsive, using her emotions over logic. As a Neo Aikido practitioner, Tenko takes pride in facing the opponent from the front, and she courageously tries to confront the Exisals. Indeed, despite being an Aikido practitioner, Tenko can be very aggressive and quickly resorts to violence, insisting that it's self-defense. She takes pride in inventing the Neo Aikido along with her Master throughout the game. Due to past experiences and her Master's irresponsible teachings and anti-romance stance, she feels a strong hatred towards boys, to the point of referring to them as "degenerate males" and openly stating all men should perish. She believes that interaction with boys will drain her Neo-Aikido spirit, and thus considers them her enemies. Contrasting her hatred toward boys, Tenko likes other girls much more. This also includes trans girls who have had gender reassignment surgery. As she is so impulsive and reckless, Tenko occasionally doesn't notice other people's feelings and does what she wants instead. However, seemingly as a part of her Neo Aikido skills, she has a unique ability to read the emotions of those she throws. Despite her loud and aggressive nature, she is polite to everyone, even boys.
