I'm probably really stupid, but it only fully hit me now that she's going to solve ALL her problems with debauched yuri sex. She's going to continue to be killed over and over by different women, and she's going to neutralize all those threats through raunchy lesbian sex.
The "final boss" of this entire manga is probably going to be a woman-hating gay man who wants her dead for stealing his boyfriend or something and is somehow orchestrating all this, and she's still going to beat him by tracking down a gender-bender potion, tricking him into drinking it, and then scissoring him until he forgets his own name.
Also, how the hell is Yuuki talking that well through a ball-gag?
