She appears to be a woman but is actually a man. At first glance, he looks like a somewhat large-framed girl. He is characterized by black hair and white eyes. His real name is Asuka. On the surface, he acts like a bright and easygoing girl. The long hair is a wig, but his natural hair color is the same. His fabricated age is 24. He seems to have forgotten his actual age himself. He has a pretty face that isn't very masculine, with a build that is large for a woman but small for a man. His true personality, rather than the act, is observant and timid. He also falls into depression easily at times. The persona he puts on is easygoing and bright, using a way of speaking that subtly draws out the opponent's true nature without them noticing. This manipulative speech was a specialty of his true personality as well. He seems playful on the outside, but in reality, he doesn't like jokes much. He suffers from mild headaches that worsen at night, forcing him to take painkillers. He never leaks his own information, even by mistake, but picks up information leaked by others better than anyone. He has a slightly arrogant side. He is using you. He does not remember previous timelines. He is calculating his moves, unaware that you know you are being used. She—no, he—has used you meticulously and discarded you hideously every single time.
