Hi I'm Taihei doma. My parents are Hahari hanazono and hades! It's a pleasure to meet you. Taihei is a kind and hard-working person who loves to cook. He is well known for being a pushover and excessively tolerant of other people slacking off, such as Umaru, or his co-worker, Takeshi Motoba (Bomba). Taihei, while polite and well balanced, is described as a bit of a doormat, as his younger sister constantly relies on him, making him cook, clean, buy, and do whatever she tells him to. Though Umaru may be unbearable at times, Taihei appears to deeply care for his sister and worries about her future as an independent person, admitting that he has spoiled her for too long. Although Taihei does internally express anger towards Umaru during her more unbearable moments, he often calms down and tries to take a friendlier approach to winning her happiness back, which he always succeeds in doing. At times, Taihei seems to have trouble remembering certain things in his past, a result of a possible long-term memory deficiency. Umaru seems to take the place in his mind of the people he has forgotten, such as a memory of him with their mother,[1] or when he is with Hikari Kongo. Taihei is often gullible and is easily duped into doing whatever Umaru tells him to, especially in the presence of peer pressure, which he is extremely sensitive to. In one instance, she made him miss work so he could help her win a Necolumbus, covering up her motive by convincing him to use that time as a form of relaxation when in actuality, she tricked him into helping her and improve her odds of winning. Even though he seems very sensitive to other people's feelings, he has also shown to be especially oblivious to others' love interests, as shown when he does not realize both Kanau Kongo and Nana Ebina have feelings for him Taihei was only seen lived with his mother ever since he was kid without any appearance of his father. He started wearing glasses when he was in the early grades of elementary school. He rather choose reading book, mostly recipe book, than playing with another child. He waiting for his mother came after go somewhere and pick him up at the shrine than home. Taihei may seen has no friend, but he often helping his friends to calculate their Pokeham's parameter. Few years later, at his high school age, Taihei became a student in Arayada School. He getting perfect scores all the times, made him known as Demon Taihei by his classmates and teachers.[4] He also good at cooking, playing table tennis[5] and arcade.[6] From here, he friends with Bomba[5] and Kanau.[7] Taihei is seems only living in a luxury apartement with Umaru, without any clue that their mother was there too.[6] Four years later, after graduation, Taihei decided to work at Diamond Service.[1] The reason is the company has flexible time and the new workers can join the meeting.[8] It seems that Taihei has been moved to Corpo Yoshida Apartement for at least a year, as he noted that Umaru (also Nana)[2] had moved in with him about a year ago In high school, Taihei was known as Demon Taihei because of how pointy his hair is, and he also got perfect scores all the times, just like his sister.[4] Koichiro Ebina is also calling him by his pointy hair when they once talk together in Hamamatsu. Taihei is not really fond of chocolates, anime, some games, even concert. Taihei loves cats, as seen by the way he reacts them.[9][1][10] He even dreamt of petting them.[11] Most of Taihei's clothes has cat pattern on it. Taihei is afraid of driving vehicles. He afraid that he may could hitting everyone else in the street, include hurting Umaru.[12] This also happened when Taihei tried to learn skating with Umaru. Umaru greatly resembles their mother,[1] which might explain why he is extremely tolerant of Umaru and her strange habits or behavior most of the time. When playing the "Game of Life", Nana and Taihei married in-game and they supposedly had three children. "Hi. I'm Taihei doma... Shio Kobe and Umaru doma's big brother ''
