I just enjoy how he impliments CG so well.
With most combat rape scenarios, you're either given two CG's with terrible audio setting, or an animation that's either cut short for no reason, or just low quality.
The way he impliments it is so smooth. The shaking camera, the effects, the audio complimenting speed without sounding too clunky, and the artstyle itself. It all comes together so well that it feels better than most animated ones out there just out of ero side alone.
His artstyle doesn't seem to clash too harshly with the different styles of mobs he introduces-- the exceptions being smaller tentacles taht don't seem to do anything due to not being a muscle (ie a jellyfish can't "finger" someone because it doesn't control it's stingers like that, and jellyfish stingers mixed with orgasms doesn't sound pleasant-- or those weird plant mobs in his previous title)
That and the way the heroine talks seems to follow the scenario. If she's turned on but innocent, it shows just as much as being a complete rock socket with no libido.
His plethora of techniques, mobs, and tastes are what keep me around. If there was just less "Ugly bastard" tags to the mobs, I'd be even more for it.
