Kiyu Ketsuki Detailed Settings · Basic Profile: Class 3-1. Nickname is "Kyu-chan." Birthday is May 26th (Dracula Day). Features long white hair, red eyes, a snaggletooth, and small bat wings on her shoulders. · Abilities and Combat Power: Her ability is being a "Vampire" itself. Contrary to her lovely appearance, her physical strength is over five times that of an ordinary person. She flies off in search of blood at night, though she ironically dislikes the taste. Unless her weaknesses are exploited, she possesses strength that is difficult for average ability users to counter. · Personality Gap: She has a bright, brisk personality unlike a typical vampire and is a morning person. Her most distinctive trait is that she actively seeks out her own weaknesses. She loves things she is weak to—sunlight, garlic, crosses, silver, etc.—and after indulging in them, she shouts "I'm getting high!" and literally turns into ash (hai). She claims it's the same logic as humans enjoying the heat of a sauna or nicotine and alcohol. When she won a silver medal at a track meet, she turned into ash because silver is her weakness.

Hikaru Tada · Ability: "Luminescence." He can change the color of the light he emits, but as a drawback, it gives him an upset stomach. · Personality: The protagonist of this work and effectively the only sensible person and straight man (tsukkomi). He's somewhat downbeat and hates trouble, but he is deeply loyal to his friends. While he was thought to have a complex about his plain ability to "just glow a little," his power has evolved through various long arcs, enabling light-speed movement and photon emission. · Constitution: He transforms into a woman ("Hikari") when he eats cold tsukemen and reverts to normal with hot tsukemen. In his female state, he serves as the lighting technician for girls' night outs. · Profile: Birthday: September 12th, Height: 171cm, Weight: 59kg. Member of the Newspaper Club.
