Original available as part of Asanagi's fantia collection:

Based on the collaborative doujin Ijou Nouryoku Kenkyuukaihatsu Kikou:
/g/1392245/058bed4649/

If you’re a lover of thick thighs, this doujin is not for you.

When her fact file brought up how much money she had, I thought Cup Collector was going to exploit not just her body but everything she owned, like with Korwa in Victim Girls 21. Apparently that was not to be. I wish they gave Cup Collector a bit more of a personality… Otherwise, top tier horrific doujin.

The collector is living the dream
Kinda wish she would use the save point for something though, like trying different kind of mutilation

This is insanely hot, but fuck I was disappointed with the end.

Should have abused her powers to get into more fucked up situations.

"A save point can freely created at any time, but because Yuria can only have one save point at a time, if she gets injured or in trouble making a new save is pointless."
Well gosh golly gee, I wonder what's going to happen?

This desperately needs a full book, Asanagi-sensei pls

Eh, I get what he was going for with 'save overwritten' but it is a missed opportunity.
If she really wanted to go masochistic she would have restarted and put her save point right after she was captured but before she got amputated.
That way she could relive her defeat, degradation and amputation all over again as often as she wanted.

Another one for the “wtf is wrong with me fap” books.
I walk a fine line with such extreme S&M, but drawings don’t have ethical concerns so whatever.

Asanagi kind of gave up on drawing her feet for the cover, huh?

@Gespens I think he gave up on her feet in general in this doujin

I feel like the idea for this one might have come from Undertale. She's basically Frisk, only a mind-broken masochist.

So as she creates saves closer to her predetermined time of death, the amount of time remaining from save point to death decreases exponentially, as would a mathematical limit. Eventually, the universe effectively ends at the point of her death, as she is the only being with a continuous consciousness and every other human exists for a mere fraction of a second at best.

The correct punishment for being a save-scumming cheater.
Unfortunately this includes myself. X-COM percentages are bullshit.

@aggron1979: Fells like that glasses girl from UQ-Holder to me, cuz of the mention of making money in the stock exchange and such.

Decent, but has the same things I hated about pretty much everything else in the original collection. Just trite and noncommittal to what its appeal could have been, and extremely uncreative with the premise set up. It would have been nice to actually see the things described in her backstory play out, but instead we just see her head into the death zone, skip over any actual guro, and get an extremely unsatisfying end for her. That's how just about everything in the original played out, and I was hoping omake content like this would explore the setup more, not just repeat the original's mistakes. At least this one didn't involve the excessively overused something something power limiters exploited against her thing that close to half the girls in the original got hit with.

2 year old comment but just wanna say: This is sadly my issue with all of Asanagi's works. They're hot as shit but god dammit, I wanna see more of this. He shows a small amount and skips over anything that would actually be upsetting, maybe shows some girls bruised up, maybe shows them dead on occasion, but doesn't do enough. He's popular so I feel like it's just him trying to not push it too far for people who can't handle any more than this.
