He is one of the heroine’s childhood friends. So far they always have been in the same class and school. He is the class president and member of many other clubs. Because of these busy activities, he does not have much time to hang around with his closest friends. He is the son of a high rank investigator. Thanks to that, he has acess to the most recent news and knows more about the recent murders
He is a dare-devil like the heroine, the only difference is that he is willing to take higher risks. He is interested in many things, thus he joined a lot of clubs. Despite his careful look, he is a hard worker and smarter than most of his classmates. Since the heroine is not informed with the news, he likes to tease her. Ikuya is not safe either from his jokes.
