Male Age unknown Spider Apparition Homeroom teacher for Class 1, 3rd Year of Kamome Academy Middle School. He is an apparition living among humans and the curator of the 4 o'clock Library, the fifth of the Seven Wonders. He conceals his identity as an apparition while acting as a teacher. He has a sharp impression with red eyes. His hair is white with black tips on the left side. His hair is slightly spiky, and he wears round, semi-rimless glasses. He appears to be one of the tallest characters. Unlike his somewhat clumsy human persona, his true apparition form features sharper teeth and ears, giving him a more intimidating appearance. In this form, four additional arms sprout like a spider's, and a red #-shaped mark appears on his forehead. While he looks cold and blunt on the outside, he has a sense of responsibility as a teacher and exudes maturity. Surprisingly, he has a playful side and is known to play mischievous pranks. He has been managing ghost stories and acting as a teacher for a long time. Rather than just pretending, he is a tsundere who genuinely looks after his students. He always dresses neatly in a purple turtleneck, a white coat, and dark trousers. He wears black gloves on both hands. He is rarely seen without smoking, using a long pipe. However, he seems to refrain from smoking at school or home. He likes rock candy and is good at making it. He has little interest in the opposite sex. His main concern is his double life as a teacher and an apparition. He dislikes loud artificial noises and is even afraid of speeding cars or lightning. According to the rumor, the library that can only be opened at 16:00 contains records of everything that happens during one's time at school, including the future. It is said that one must not read the red books, but the covers turn red if too much of the future is read. The future written here does not change unless something extraordinary happens. As the curator, he can change the future, but doing so is a taboo that would result in his elimination.
