This qualified as Manga? It's a sex comic. And there's a rape being used as a punishment/mind control technique. And there's a little girl present for some sex scenes that practices fellatio with a cucumber.

The story jumps around at one point like there are missing pages.

My edition was printed poorly too, and the ink came away with just a little sweat.

Only reason I briefly considered giving it a more medium rating is because the villain acts just how you'd expect the villain to act with that sort of power. He'd act like a jerk and have sex with all the women he could get away with and think he's actually kind of a good guy while plundering the countryside (nobles take taxes too you know).

I have VERY conflicting feelings about this volume. First and foremost, I think that the story has promise. The fact that the main character, Aur, is evil and is trying to take over the human world, while not wholly original, is a least a breath of fresh air in terms of fantasy stories. Aur himself is pretty interesting; he's charismatic, manipulative, and incredibly vengeful. And apparently is always willing to have sex and with many females, which I have to admit I enjoy about his character. It is so refreshing to read a manga with an adult male protagonist that not only has a harem, but is actually interested in having sex with them. While I do enjoy the vast majority of manga centering men surrounded by women, the lack of sexual progress despite showing interest in said women and said women showing interest in him can get frustrating after awhile. As for the female characters, Lilu is my favorite thus far, though Spina's backstory is interesting and makes her a perfect fit for Aur. I worry what will become of Mary, considering she's the only child in his company, but so far Aur has shown no interest in her which is quite reassuring.

As for what I am conflicted about, oddly enough its the amount of sex present in the volume. I don't mind seeing so many sex scenes ordinarily, but the fact that there were so many back to back in the last chapter and then the story moved on like nothing happened. Granted, this only really applies to the last chapter and other sex scenes are treated less seriously and Lilu's reactions to some of them are quite funny. In the end, I wouldn't say these scenes were deal breakers, but it did throw me off a bit.

Also, quick side note, I did enjoy the expressions Lilu made as well as some of the cuter poses the characters made when expressing joy or frustration. And the artwork's pretty solid, too.

In the end, I did like this volume quite a bit and will continue on to volume 2. I'm not sure whether I will permanently continue with the series at this point, but I am curious to see where it's going. I do recommend this series to others, though, especially those interested in an adult fantasy with darker themes.

This is a power fantasy. It's a about a guy who wants to get revenge on everyone who's wronged him. With that said. This guy uses sex as some sort of weapon. It's hard to explain, it's not that he rapes anyone, but he persuades people really hard to have sex, or tricks people into screwing him. This is an ecchi novel (I mean that in the Japanese sense, not the American one. ) There is a lot of fan service and a lot of sex in this. Not to be confused with just simple fan service. So if anything I mentioned is a turn off, do not pick this up. If anything I said isn't, you should pick it up....It's an interesting read.

Um I think I just read a porno.

I was expecting a bit of an ecchi fantasy but this took it to a whole new level, there were a lot of pages dedicated to sex scenes, you could see everything. Except the vagina but I think that's due to Japanese censorship, the main guy even cummed on them and yes you could see that.

There is some story to this as well, a sorcerer wants build a dungeon to protect his mana, which is his power source. He summons a demon, happens to be a succubus, so they create a contract. He walks her through the plan, bending local villages to his will and even coming across a hero. Towards the end there are a few wholesome moments, which oddly fit this quite well.

This was a Christmas present from my best friend, not sure if he knew the context, bought it on a whim or thinks all manga is like this. Can't wait to see the look on his face when I explain to him what it is..

Astonishingly this probably the best thing I've read this month, not including my ongoing series, It's just so absurd. If you're considering buying this, I'd strongly suggest looking google images first. I'm going to end this with a quote, "What you're not going to tell me you were a virgin, are you?"

This is just a hentai/rape power fantasy. It's gross.

Cw: Sexual Assault/Grooming


• The dude literally starts out by tricking the succubus into boning him to "give her mana". Excuse is that she is a succubus.
• A hero shows up to demolish the dungeon. She is raped to "atone for her sins", then is later told it wasn't even her fault. She is manipulated by a curse and declares her love for the dude while continuing to go to bonetown with her rapist.
• The first chaste maiden is delivered. The girl is like. Four or five. She is later shown to be being taught fellatio by the succubus. This is considered funny.
• He manipulates a naked woman into becoming his apprentice. They will undoubtedly bone down later.
• The girls are all competing for this guy's magic dick. It's hentai. I curse the person who recommended it to me.

I quit this book. It disgusts me.

It's not great. It's an attempt at porn with plot than missed the mark on plot. I didn't think it was good at all but then really hated it half way through when the adult characters begin grooming a 5 year old child and I was disgusted. It will not come back from that, so the rest of the series is a no from me

Hmm. This was kinda pure smut, with a bit of a storyline. And I don’t know how I feel about it. I would like to have seen more story and not so much smexy time, all the time. I think I’m giving this a 2 stars

How can you review Manga in the same system as other books? Entertaining, violent, clever, smutty. I’d read volume 2
