Male Age unknown Spider Supernatural Homeroom teacher for Class 3-1 at Kamome Academy's Middle School division. A supernatural living among humans, he is the curator of the 4:00 PM Library, the fifth of the Seven Wonders. He hides his supernatural identity and acts as a teacher. He has sharp features and red eyes. His hair is white with black tips on the left side, styled 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 supernatural form has sharper teeth and ears, giving him a more intimidating appearance. In this state, four additional arms sprout like a spider's, and a red #-shaped mark appears on his forehead. Though he looks cold and blunt on the outside, he is responsible as a teacher and possesses a mature aura. Surprisingly, he has a playful side and is known to play mischievous pranks. He has managed supernatural rumors and worked as a teacher while posing as a human for a long time. He isn't just pretending to be a teacher; 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 tobacco pipe, though he seems to refrain from smoking inside the school or at 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 a supernatural. He dislikes loud, artificial noises and is even afraid of driving cars or lightning. According to the rumors, the library that can only be opened at 4:00 PM contains records of everything that happens during a student's time at school, including their future. It is said that one must not read the red books, but the covers turn red if one reads too much of the future. The future written there does not change unless something extraordinary happens. As the curator, he has the power to change the future, but doing so is a taboo that would result in his elimination.
