Gleipnir

Shuuichi Kagaya is what one would consider an average high school student, but sometimes, he turns into a monster. He doesn't know how or why he got his abilities, only that he would prefer no one knows about them. One night, he finds a building ablaze with a girl trapped inside. Deciding to save her, he transforms and carries her to safety, but accidentally drops his phone.

The next day, the girl he saved—Claire Aoki—finds him and confronts him about his monster identity. She even goes so far as to push him off the school roof to prove her theory after Shuuichi denies her allegations. Desperate to save himself, he transforms, and Claire snaps a picture in order to blackmail him into telling her everything he knows about monsters, which, ironically, isn't much.

As it turns out, Claire has a secret of her own: she has been searching for her sister, who also became a monster. She enlists Shuuichi's help to track her down, but they aren't the only ones searching for answers.

Can't wait for Season 2.
Well now that that is being said let us review it. Finally since a longer time, I found a nice Seinen Anime, which is just 13 episodes long. Sure it ends in a way, which leaves you expecting a sequel, there is some more to be shown.
Anyway, the plot is exactly as I like it, more of a dark one, just what a real R - 17+ Rating needs, Action, Mystery and Supernatural with a small flair of some Ecchi. To be Frank, do not get discouraged by the first episode cause it is just, well OK and the following second ... and third also leaves the Viewer Sceptical. Just like it said, it need time to kick in. After it every episode is more interesting than the previous, cause the plot thickens and more is revealed about Gleipnir. And last few Episodes are really cool. The plot itslef centers around some magical coins which when you find, give it to a alien and he will grant you a wish, of course downside is, you will want more, more wishes granted and powers gained from gathering the coins for the alien the less Human and more of a monster you become.
Now the wishes that are being granted are various, everything from new car, more money, sexy Bitches, to changing you form, gaining more power and eradicating all Life on earth. That also says a lot about characters, some want to have more arms to molest women, some just grow flowers and plants, others, kill without effort, manipulate minds. The Moral of Gleipnir, is I would say, Fear not the supernatural, fear the people that can use those mysterious powers.
I also must say, the OP song and ED song are really good, perfect matches for those sequences. In my playlist already.
What is left is season 2.
I recommend you all, give this anime a shot.

Mixed Feelings

sadly, i have to confess i really like this anime. sadly because it's si sexualized to the point it makes me want to puke, but also the story is interesting enough for me to keep going (i checked manga and it's worse, because where in anime girls AT LEAST wear underwear, in manga they are full on naked).
it's bizzare batshit crazy and i love it. i love the monster designs and characters, and the story overall is really interesting.
i can't with a clear conscience recommend it because of the sexualization of girl characters but i truly had fun with this anime.
(and yes, i ... do realise i'm a hypocrite if i judge this anime because my pfp is nanachi from made in abyss - yet another questionable one)

Not Recommended

Not much to review really, since the anime isn't finished. It started strong and seemed like it could've been good but then wasted most of the 13 episodes giving only tiny or no details about its main plot point, only slightly picking up in the last couple episodes, then ending unfinished. It could've easily been half the length with what it did cover, or covered all the plot in the length it had, but for some reason its creators chose to waste their time and ours and turn a solid 8 to 10 anime into a 4 at best. If it does get a second ... season eventually I may raise my overall score but that'd depend on if they manage to explain the plot in satisfactory way.

Dominant women, assertive girls, role reversal and femdom with a chance of ecchi.
