Story: I don't know why no one mentioned this about the story; I found the story more appropriate for hentai genre (Although there were no inappropriate scenes) but the story itself revolve around a sick guy who tried to make his mother bear his child but she refused him then goes around trying to kidnap his half-sister (sister from his mother) to make her his wife. Sound: I think the songs they used were very good; I even thought about having one of the songs as a ringtone for my mobile phone (I am still planning to but I'm just too lazy to do it)
