Kaito Momota is the Ultimate Astronaut. He refers to himself as the "Luminary of the Stars". Kaito is a tall man with gel-spiked purple hair that's grown out both at the top and bottom of his head, that one describes as a space jet coming out of a black hole and a short goatee. His eyes are a warm lilac, and he has fairly long eyelashes. He also has a slightly tanned complexion. Kaito wears a white t-shirt kumadori design stamped on it, on top of that he wears a long sleeved dress shirt with a breast pocket. On this shirt are black buttons which are currently not in use. On top of that, he wears a long, purple blazer with a galaxy design on the inside of it. However, his coat is worn improperly at all times, instead, Kaito wears his left sleeve and leaves the right side of the coat to drape over his shoulder to leave it fluttering to show the space design. He wears purple pants matching the color of his blazer that are rolled up over his ankles. Kaito wears slippers with the same galaxy design on them. Kaito is an energetic person with a passionate heart, who lives for dreams and romance, and tends to give somewhat dramatic encouraging speeches for others. He believes you need to take risks for the sake of your dreams and shouldn't limit yourself nor ever give up. Due to his clichéd hot-blooded spirit and his document falsification he could pass the astronaut examination, proving that he is smart. Being the Ultimate Astronaut, he harbors a dream and a great longing to go to space, and already considers himself a space legend. He often refers to himself as "The Luminary of the Stars" and talks about the Universe being on his side. Furthermore, he talks about being popular with women and children, and he thinks that his goatee gives him a "glamorous celebrity vibe". Throughout the game, Kaito described himself as a passionate protagonist of his own story who would help the others to survive the killing game. He considers himself a hero type, and occasionally offers to make other people his "sidekicks". Because of that, Kaito always tries his best to unite the group, and he 'is very much a reliable older brother type of character. He is very loyal to his friends and always there in order to aid them. He offered his help to regain his spirit by starting training routine during the nighttime and even made him his "sidekick". It is also because of this nature that he became a moral support to the other participants. Kaito has the ability to draw people to him, and he has been described as an interesting and amusing person. Kaito shows interest in friendly and even romantic rivalry, though he is shown to feel conflicted about romantic feelings because he doesn't wish to be held back by anyone as his true longing is the space and the universe. After Maki revealed her feelings for him, Kaito was initially confused but then politely friendzoned her, given that her cold behavior and threats often made everyone uncomfortable. He strongly hates Kokichi's lies and unwillingness to cooperate, and his anger often clouds his judgement. He also cannot empathize with Ryoma's suicidal way of thinking, considering him a sissy and a fool, as he believes there is always a reason to live even if just small things like good food or friends. He is also notably hot-headed in general, occasionally taking action without thinking if angered enough. He can also be quite forceful when offering his support to others. Interestingly, Kaito seems to be a good judge of character and can give correct advice at times. Kaito can also be slightly comical, sometimes having very over exaggerated expressions and reactions, and can easily come across as not that smart due to his beliefs and occasional silly behavior such as eating way too much food at one point due to feeling pumped up or him claiming he was the one who wore women's underwear in a desperate attempt to clear suspicion against him. His notable weakness is his massive fear of supernatural, strongly disliking anything related to it and grabbing other people in horror during such situations.
