Rintaro Senkawa

His whole life he has been a "useless"-type of guy, nothing special. 27-year-old Rintaro's lived an honest life not committing any serious offenses or anything like that. With Koyori as his devil, he seeks to get out of this hellhole and repent for his "sins" ASAP. His kindness and naive personality makes him easily leaving him betrayed and dumbfound. (Is a guy like him really cut out for hell?!)
