To me, Serena is pure fap-fuel. She's a bad rival in the game, and her anime depiction is literally enough to put me to sleep, I've completely nodded off during some of her episodes. I think she's a boring, overly simple looking character. She'd make more sense as a Beauty class trainer rather than a fucking protagonist.
And that's what's made my evolving relationship with the character so much more appealing-- I literally view her as being beneath every single other character. She is LUCKY that I've found a use for her, fapping to her. The highest fucking thing she can achieve is getting me to go on my phone in the bathroom while my girlfriend thinks I'm shitting, and busting a fat nut into the toilet while looking at a doujin or artwork of her getting raped. She's banal, simple fap fuel, only existing to make (Me) cum. She isn't worth a single other thing and has no interesting features beyond that.
