History
He is first seen with Satoru's group of friends, reading a book. He was the first one to notice Satoru's interest in Hinadzuki. He was also the one who stopped their friends from teasing him about it. Since he had a keen eye, he had already noticed Kayo's bruises and quickly noticed the difference in his friend' behavior and confronted him about it. After Satoru explains things to him, he offers to him him achieve his goal. He stopped Satoru when he tried to attack Kayo's mother and suggested the hideout for Kayo after he heard of Satoru's plans.
