Hi guys, i really need your expertise about anime. Back once i was a little boy(age 7 year 2005-2007 i guess) i was watching an anime but i really couldn't remember the title. What i remember is that there was a nun, along with the evil one who controls her will. The main character really want to save her but the problem is that he is a demon so he can't touch/ help her. I tried searching in internet but i cannot find it. Please i need you guyz, thanks!
