Male Age unknown Spider Apparition Homeroom teacher for Class 3-1 of Kamome Academy Middle School. An apparition living among humans, he is the curator of the 4 o'clock Library, the fifth of the Seven Wonders. He hides his identity as an apparition and acts 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 frightening appearance. In this state, 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 is responsible as a teacher and possesses a sense of 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 concern is his double life as a teacher and an apparition. He dislikes loud, artificial noises and is even afraid of moving cars or lightning.
