MALE TENKO

As a child, Tenko suffered from severe anger tantrums and over-activity to the point that his parents were worried that he might not be able to fit into the society. Not knowing how to handle him, they sent him to live in a temple to help discipline his mind.

However, it seemed that Tenko was trouble even for the priests, so they had to come up with something else. During his mental training at the temple, he 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 him notably calmer, though he still remained very aggressive and overactive when compared to the norm. However, he also seemed to take the made-up martial arts a bit too seriously and dreamed of making it a national sport.

The Master also began to use Neo-Aikido as a way to develop Tenko's moral compass. As practitioners of Neo-Aikido, Tenko and his Master even used to wear masks and acted as "heroes of justice", helping people during day and night. This included things like carrying old men's belongings, helping children cross the street, catching thieves, punishing cheaters and sexual predators, and even helping boys who had tough break-ups.

In order to control his bad habits, the Master began to claim that various things would weaken his Neo-Aikido spirit and thus should be always avoided, such as being too excited about Christmas or Valentine's Day, eating more than three sweets a day, or failing to keep the environment clean. Because of his anti-romance stance, he also wanted him to not get close with girls and thus told him that interaction with them would weaken his energy. Tenko believed everything without question and took it all very seriously, and he had very little interaction with girls.

He already had a dislike for women, seemingly due to all the sex offenders he had seen on television, but this turned into hatred as he begun to consider all women enemies that would drain his spirit and prevent him from mastering Neo-Aikido. He believed that girls shouldn't even touch him. Other bad influences from the Master included the belief that ex-girlfriends deserve severe physical punishments, and that you can even use unfair methods such as weapons, breaking their bones, or attacking before the match starts.

Tenko is a boisterous and generally cheerful person. He wears his emotions on his sleeve and has the habit of yelling out in a loud voice to show his fighting spirit. He suffers from overactivity and anger issues and directs all his energy into his Neo Aikido. Even still, he claims he is much calmer compared to his childhood. He has also described himself as "not very good at thinking" and appears quite gullible and impulsive, using his emotions over logic. Due to past experiences and his master's irresponsible teachings and anti-romance stance, he feels an intense hatred towards girls, to the point of referring to them as "degenerates" or "sluts" and openly stating all women should perish. He believes that interaction with girls will drain his Neo-Aikido spirit and thus considers them his enemies. Due to his misogynistic outlook, he makes up stories about how bad girls are in his head, such as that girls are much more likely to do negative and deceiving things than boys, like always being the first to lie and always shifting the blame right away. He dislikes girls so much that even the nice things they do to him, like asking about his day or giving him a gift, can cause him to react negatively. For example, he doesn't like girls praising him. If a girl compliments his looks, his expression will die instantly. He also never allows a girl to touch him, throwing her reflexively or taking a step back if they even attempt to try. His dislike of girls is portrayed as a very emotional and irrational opinion. There are moments when a girl acts sensible and Tenko feels like agreeing with her but later refuses solely because they are a girl. However, since there isn't much of any actual reasoning behind his dislike for women, there are moments when he seems to completely forget his hatred for women and cooperates or compliments them before quickly stating "for a woman" as to show them that he still hates women.

Contrasting his hatred toward girls, Tenko likes other boys much more. This also includes trans boys who have had gender reassignment surgery, supported by the fact he wants to shake Shuichi's hand but begs her to have gender reassignment surgery, so he is able to do so. During dangerous situations, he recklessly rushes to protect all the boys, and only them. He also gets very shy and humble if a boy compliments his looks, blushing strongly and insisting that his looks definitely aren't as good, and gives excuses such as his face getting all wrinkled every time he drinks from a straw and his eyelids turning inside out whenever he washes his face with a towel. He believes that expressing your feelings is completely natural, and you shouldn't feel ashamed of them, whether it's crying, laughing, or anger.

Despite his loud and aggressive nature, he is polite to everyone, even girls. His politeness is so powerful that it surpasses his hatred toward girls. He also accepts girls to be practitioners of Neo-Aikido out of necessity, though he isn't fond of the idea and just considers them "tolerable." However, it's also indicated that this ideal person must also be proficient in Neo-Aikido, noble and not the type who constantly thinks about sex. He considers any Neo-Aikido practitioners his comrades with a bond thicker than blood and is also very loyal to anyone he considers his best friend or a role model, female or not.

As a Neo Aikido practitioner, Tenko takes pride in facing the opponent from the front, and he courageously tries to confront the Exisals. Indeed, despite being an Aikido practitioner, Tenko can be very aggressive and quickly resorts to violence, insisting it is self-defense. He takes pride in inventing Neo Aikido with his master. Throughout the game, he constantly threatens girls or Monokuma with his Neo Aikido techniques, saying it is potent and deadly. However, he admits that compared to Gonta's incredible power, he had no match for her. He has also admitted that he actually has a very low tolerance to pain and is terrified of the idea of torture. He also occasionally has a panicky side in other situations. He seems to panic in a Class Trial if suspected of being the culprit and tends to react strongly.

Tenko is a young man of average height and a relatively fair complexion, with somewhat broad shoulders and an athletic, muscular build, likely due to his relentless Neo-Aikido training. He has rather thin, wavy, dark olive-gray hair tinted with green. His bangs are slightly swept to the right and cut in a choppy fringe, two thin strands of hair left loose to frame his face, the right strand curving inwards and the left somewhat longer, curving outwards. His eyes are a warm green and sharply angled, like a cat's of sorts. He has a small mole towards the left below his bottom lip. He has a wasabi-green napkin or cloth with a white floral print resembling a four-pointed pinwheel stuffed into his pocket. And a lilac hairclip decorated with a paler colored six-pointed star holding his bangs. He wears a white collared undershirt with an ivory-colored necktie with a tieclip, a faded blue, cropped, long-sleeved blazer with two pockets and six white buttons. His previous high school's symbol can be found printed in black at both his sleeves' shoulders. With this, he wears pants with the same faded blue as his uniform but the hems are rolled up above his ankle. His legwear consists of calf-high white socks, and waraji sandals, which he believes to be a common martial artist stereotype. His accessories consist of a lilac choker the same color as his hairclip, a golden bell attached.
