Tenko Chabishira

As a child, Tenko suffered from severe anger tantrums and over-activity to the point that her parents were worried that she might not be able to fit into the society. Not knowing how to handle her, they sent her to live in a temple to help discipline her mind. However, it seemed that Tenko was trouble even for the priests, so they had to come up with something else. During her mental training at the temple, she called the head priest "Master" and respected him greatly, and thus he declared himself the Master of martial arts. The head priest and Tenko came up with the martial arts of "Neo-Aikido", an unusually aggressive form of Aikido, to channel Tenko's energy into constant activity. Neo-Aikido helped Tenko and made her notably calmer, though she still remained very aggressive and overactive when compared to the norm. Because of her Master's anti-romance stance, he also wanted her to not get close with boys and thus told her that interaction with them would weaken her. Tenko believed everything without question and took it all very seriously, and she had very little interaction with boys.

Tenko is a young woman of average height and a relatively fair complexion, with somewhat broad shoulders and an athletic, muscular build, likely due to her relentless Neo-Aikido training. She has rather thin, wavy, calf-length, dark gray hair tinted with green, peculiarly styled in low twintails tied with white ribbons that bear resemblance to chain-like links, each tail divided into three bunches, each bunch split in the center, the rest of the tail left loose. Her bangs are slightly swept to the right and cut in a choppy fringe. Her eyes are a warm green. She has a small mole towards the left below her bottom lip. Her head accessories consist of a large, green bow with a white floral print resembling a four-pointed pinwheel clipped to the back of her head, and a lilac-purple-pink headband decorated with a paler colored six-pointed star at the left. Tenko wears a faded blue, cropped, long-sleeved, double-breasted seifuku uniform with pockets and white buttons. Her sailor collar and sleeve cuffs are both white striped with a single blue line the same color as her uniform, a white bow tied at her collar. She wears a short skirt the same faded blue as her uniform with two layers of frills. Her legwear consists of knee-high white socks, the edges striped with a faded blue line the same color as her uniform, and waraji sandals, which she believes to be a common martial artist stereotype. Her accessories consist of a lilac-pink choker the same color as her headband, a silver bell attached.

Tenko is a boisterous and generally cheerful person. She wears her emotions on her sleeves. 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. As a Neo Aikido practitioner, Tenko takes pride in facing the opponent from the front. Indeed, despite being an Aikido practitioner, Tenko can be very aggressive and quickly resorts to violence, insisting it is self-defense. She takes pride in inventing Neo Aikido with her master. She has also admitted that she actually has a very low tolerance to pain and is terrified of the idea of torture. She also occasionally has a panicky side in other situations. She believes that interaction with boys will drain her Neo-Aikido spirit and thus considers them her enemies. Due to her misandristic outlook, she makes up stories about how bad boys are in her head, such as that boys are much more likely to do negative and deceiving things than girls, like always being the first to lie and always shifting the blame right away. She dislikes boys so much that even the nice things they do can cause her to react negatively. For example, she doesn't like boys praising her. If a boy compliments her looks, her expression will die instantly. She also never allows a boy to touch her, throwing him reflexively if they even attempt to try. Her dislike of boys is portrayed as a very emotional and irrational opinion. There are moments when a boy acts sensible and Tenko feels like agreeing with them but later refuses solely because they are a boy. However, since there isn't much of any actual reasoning behind her dislike for men, there are moments when she seems to completely forget her hatred. She is shown to comfort boys, doing other acts of kindness for them, and at rare moments, being able to admit that a boy can be a good person. Despite her hatred of men, she can respect them, though she is always surprised and confused by genuinely good boys. Contrasting her hatred toward boys, Tenko likes other girls much more. This also includes trans girls. During dangerous situations, she recklessly rushes to protect all the girls, and only them. She apparently tries to be fashionable and more attractive to girls with some of her clothing, but she is instead described as a "fashion disaster". 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. Whenever she does this, she correctly reads the other person's feelings and can give them the right kind of advice. She believes that one should express their emotions no matter what.
