A horrible porno and nothing else

How is this getting turned into an anime and that is also the sole reason i looked at the manga but i wish i didn´t. The setting is overused and creepy, the characters are just the worst and the art is bland and amateurish but if you want to read a series where the leading "lady" is raped by a half lesbian ghost every 10 pages while pissing herself once a chapter than this one is for you. If not don´t even start but manga by Dragon Age tend to be street trash in general so what did i expect. An explicit sex comedy about a ghost that is actually readable would be My Lovely Ghost KANA (7,5/10) and that Patrick Swayze movie is a decent watch too. Koi Kaze (8/10) further proves that a manga about incest can work just fine and Sensei o Mite Kudasai (7,5/10) would be an example that hentai doesn´t have to suck all the time or even be misogynistic. So stick to all of them and just walk way.
Update: The anime won the "audience price" for being one of the worst animes of 2014 by ANN so there is that too. This is shonen Borderline-H at it's worst.

This is pretty strange story to read if you're in it for the romance. The description here isn't that great since after the first few chapters, the story is revealed to be "have romantic feelings for your brother-in-law under orders from a ghost or DIE." If you can get past the fact that the sister is being forced into the situation; this is a great story. If you can't; turn around and walk away. The entire romance IS forced as the ghost frequently possesses the girl into acting out ecchi scenes and that somehow causes her love meter for her brother to increase.

When I read the description of this along with the 1st couple of chapters, I thought this would be good. However, it gets a duller after each chapter. It's one of those stories where the writer leads you on thinking something interesting is going to happen, but nothing ever actually happens. I think the manga has become flat out terrible and I can't understand how the heck it's getting an anime. If I were 12 or 13 I might like this better, but I'll never know.

Not sure what to think of this one. Not a big fan of incest, so normally I wouldn't be that interested, but there's a curious twist here so it isn't like other Onichan-obsession manga. I'll have to see more chapters before I add a rating, but it's ok so far.
