Re: りりすばとる! RJ139078
There's something involving corruption, or how addicted to succubus you are. I believe if this level is really high instead of the kissing game you get a near unwinnable battle? I've gotten it by messing around in the free play room, one of the options lets you turn it up or something I can't remember.
Yeah, now that you mention it... I found that too. The blue button switch closest to her in the replay room. Though, I seem to have found a scene "beyond" the 0-14 scale where she goes completely wild, strips, straddles, and rides you straight to oblivion. I've only found that scene twice by accident and I'm not sure the condition that triggers it.
Edit: I also note that for some of the girls use "special" attacks that use a dice roll to determine whether or not you get to experience their special attack. In a previous game published by this circle, there were skull "skills" that could not only trigger the special scenes in the replay room, but a second version of the skill that would guarantee a critical failure which would make the special attack a bit more "intense". I think that's duplicated in this game, because I ended up rolling a 100 (1 is best, 100 is worst) and getting a special-special attack. But that was just one time. I've no idea how to trigger it more regularly.
