The world has fallen into disorder, it divided into the north and the south and after kakamura has been destroyed both lands now fight over the world. capitals gave been born, one in the north and one in the south with its respective Emperor. In this age there are people who live as Shinobi/Ninjas...
The only reason anyone might want to watch "Mitana: Nin" is if they have the very unique fetish of wanting to see a woman raped by frogs… I doubt there are many people with that particular fetish, so I say to the rest of the world: do not bother watching this terrible hentai.
"Stop it… I hate it… it hurts… oh no, now I'm coming"… That is just a sample of the brilliant dialogue that is contained in this confusing, poorly animated travesty. Lets talk about the story first, its about magic using ninjas who are in search of three treasures that will let them
summon monsters and somehow overthrow evil. In order to get these items people have to have lots of sex, or at least that seems to be the way it works. To get the mirror, sleep with a priestess. To get the necklace screw in front of the mirror. To find out where the sword is, have sex with another woman since the tattoo with the directions only shows up when she is getting off. Add in a bunch of strange, magic-using enemies who's primary skills seem to be having sex with people so that they can kill them easier. The story has a lot of characters, none of which are well developed or memorable. There is a mastermind villain that wants to take over the world, but he does not seem to do anything other than appear a couple times. Things happen but I honestly can't say that the events actually add up, make sense or tell a story. The whole thing comes to a close with a big battle that just ends strangely. I had to force myself to finish watching this hentai because it was just so, so bad.
Lets talk about the animation now… First off this is censored, no surprise there, but the censorship is so bad, so overdone, so much overkill, that it by itself almost ruins the whole series. With the story being so bad, the censorship just pushes it over the top. The actual artwork is not bad, and looks good. The problem comes from the fact that they animated that artwork, and honestly I do not think the animators have much experience and very little imagination. The animation was stuttered, badly looped, and just plain uninteresting. The hentai content was high, every situation ended in sex… but the hentai animation was bad and boring. I honestly cannot say much of anything good.
I am not even going to bother talking about the sound, music or voice acting. This hentai was so bad in other ways I cannot honestly say that I was able to think about the audio content, I just wanted it to end.
So in conclusion… do not watch this crap. Do not let your friends watch this crap. Send it to the person you hate the most and force them to watch it over and over… it is a great tool for torture.
