Most of people look at this as just weird ecchi/hentai manga which it is but unlike other ecchi mangas this one have pretty good backstory backing it up. If you're more of serious family friendly person do not read this manga. This manga is for people that doesn't really care about ecchi stuff and really do enjoy weird stories. This is probably one of my favorite underground titles I read as story like this can't be found anywhere else but it is really enjoyable. After 100 chapters it's hard to not connect to this characters. They aren't really special and at same time aren't badbut after spending time with them during reading you can really enjoy them. Art for random manga like this is amazing as artist really put much effort into it. If you need something unique that you won't see anywhere else just to enjoy a good story mixed with ecchi scenes this is defenetly best pick for you
