Ikusa Otome Valkyrie

Ride of the Valkyrie (Ikusa Otome Valkyrie) has a formula that has been played over and over again. It has been tried and tested to be... well, rather popular.
You take a strong beautiful heroine and break her down physically and mentally through various heinous acts of rape, bondage, gang bang, public humiliation, and other brutal sex acts until she loses it and becomes a sex addicting slave.
If you like that formula, then you'll like Ride of the Valkyrie. I personally don't like that formula, but honestly, Ride of the Valkyrie does it quite well. But be warned! It's not for the fainthearted.

Set in ... a fantasy world of orcs, gods, and goddesses, the story (no story really) begins by portraying the beautiful, strong, and pure heroine Valkyrie.
"Look at how strong and graceful she is wearing her white robes beneath that sexy viking styled armor. Look at her kill all those big fat ugly orcs in battle. Such skill, such grace, such power! Look at how pure she is, bathing under a waterfall in an enchanted forest. How beautiful. Wow!"
(an ominous laugh)
"Now look at her chained up, about to loose her virginity to a bunch of big, fat, hideous looking orcs. Aww..."
If you're looking for a light at the end of the tunnel, you're not going to find it here folks. Well... I guess her mind breaks and she begins to enjoy getting stuffed in all her orifices. She's joined by her twin tailed loli friend, Skuld, later on as well. But really. No. It is very dark themed.

I guess where Ride of the Valkyrie shines is in its art and animation. The character design is rather good looking. The animation is rather smooth and fluid with attention to detail like how the her breasts flop back and forth as orcs take turns violently thrusting their fat cocks in and out of her; uncensored, might I add.

Character is also pretty good. We get the heroine, Valkyrie, who is strong willed, but not arrogant. She's a bit of a tsundere. At some point, she begins to enjoy sex with orcs but she won't admit it. There's Freya, who betrayed everyone first, by losing herself to lust. She has a rather mature motherly aspect to her and encourages Valkyrie to enjoy herself. Then there's Skuld, the twin tailed loli type who's witty and arrogant and bit tsundere herself. All well portrayed by their prospective voice actresses.

Strictly from a hentai perspective, the fap value of Ikusa Otome Valkyrie is pretty high. But residual feelings of guilt will be a factor as you convince yourself "It's just fantasy. No kittens were killed in heaven."
There's plenty of different kinds of play, including rape, gang bang, chain bondage, public humiliation, piss/scat, tentacle sex by purple slug monsters and some rather novel transportable penises for some futanari sex scenes. Plenty of bodily fluids of every kind: virgin blood, blood, tears, saliva, gallons of semen, as well as vaginal fluids. There's lots of violence as limbs get lopped off, heads roll, female prisoners get rape as the male prisoners watch helplessly (NTR?). It's pretty extreme. There's no lovey feelings. Just sadness, misery, aggression, and sexual arousal that screams at your Id, while your Ego is crying, and your Super Ego has already left the building.
