Оригінальне ім’я: アルネ・ノインテーター
A vampire who practices detective work under the belief that “solving mysteries is meant to be enjoyed.” Originally the “most fearsome” being with nine hearts, he has now lost several of them and switches between the forms of a boy and an adult depending on the situation.
