I really don't see how people find Pippa attractive. The more she talks aboit herself, the grosser she sounds. She just leaves garbage everywhere, she lets ants crawl all over her. I doubt she baths regularly. You'd have to be extremely desperate to want to get with her.
Hell, that goes for the rest of the PCs girls as well. They're either just as gross, completely unstable, annoying as hell, or a walking medical bill. They're fun to watch from a far, but I wouldn't want to touch them with a 10 meter stick.
the sexual attraction comes from the fact it's an anime girl doing it
in fiction, you can pretend and replace stench with aroma, garbage with decoration, ants with witnesses to your passionate bed-breaking fucking, mold with lubricant, etc etc
But I dunno, it's hard to describe what exactly is appealing about her. I guess a lot of it comes down to her personality. She seems genuinely fun to hang out with and talk to, almost like she's "one of the boys", but with added benefits. I definitely think I'd be grossed out seeing how she lives in person, but I suppose there's a part of me that thinks I can fix her lol.
TLDR: Honesty.
Explanation: Psychologically speaking honesty is possibly the most prevailing generally attractive aspect of any person throughout the entire human species across millions of years. You can be a sociopath, spineless wimp, herculean giant, or a midget. When someone's honest to you and ONLY honest to you there's insanely high chances you will find this attractive, be it attraction to friendship, sexual coupling, or perhaps even business prospects.
In regard to Pippa, her being upfront about gross shit can be interpreted as he being extremely honest about everything. This translates to people building a sense of trust towards her which then turns over into a broad attraction. One of you pointed out
She feels like one of the boys which is one impression. Others get sexually attracted to the thought of a girl not putting on a facade around them and just being 'herself'.
This can extend to the rest of the PC girls in a sense. They all sound awful but that means none of them are putting up a facade to look better than they actually are. Which again, translates to a sense of trust and therefore an attraction towards them in some manner.
In comparison go look at someone like...Froot or Nyanners. Easy examples.
Too easy. But they fit the bill of chicks which really mask their flaws and shortcomings as much as possible to present themselves as close to perfect as they can. As a result they have huge amounts of people who hate them for all the flaws people discover and realize these girls either still have, or refuse to ever acknowledge they even did. Hell, I'll make a hot take here that if Froot was upfront years ago she'd been a fuck up and cheated on her husband/regretted it she'd have WAY less hate than she does now. But then again if she did that, she wouldn't have also went ahead and scammed the Twitter-Tranny community. So eh.
As a closing note: It's worth remembering sometimes guys want a girl that doesn't try to be perfect. Sometimes what a guy wants most is a girl he doesn't feel /forced/ to put on a pedestal. But rather something like... "Yeah she isn't perfect- but she's perfect to me." Type. Not even a "I can fix her" sort of deal because I personally view that approach as heavily short-sighted and careless.
