Persona x Detective Naoto
One of the five judges behind the Midnight Site that delivered anonymous judgement on strangers, Osamu's handle on the site was Omoikane. A twenty nine-year old man, he was the first judge that accepted the Yagokoro's offer to shelter him when the mysterious killer Kagutsuchi began targeting the judges for revenge. He is naturally paranoid and finds most of the police threatening, leading to Naoto Shirogane dressing in a girl's uniform to lower his guard and force him to open up to the police. He reveals to her that he met the other judges on a blog that served a similar function when they decided to make the site.
He is killed in his sleep while in police custody.
