Mooms is good for her craziness and I enjoy how it's been said that she's caused the black plague and various other disasters throughout history, but she practically clings to FauFau's massive tits while trying to invite Kronii to suckle from the other one. However, we also saw how dominant Kronii can be with FauFau in the Bread & Fred collab where Fauna can't keep up her onee-san role around Kronii's little bit of dominance. Christ, thinking back to that collab frustrates me for whatever happened with Kronii and Fauna after all of that intense flirting between them during that stream and the off-collab, but that's unrelated.
What is related is that Shiori is chaotic and unhinged enough to throw Kronii off-guard while being enough of a flirt to hit Kronii's weak points. There is no doubt left in anyone's mind that Kronii has a petplay fetish, and Haachama exposed that point dearly during the ramen-eating collab between them. And yet, only Shiori and maybe Gigi would go far enough with the petplay jokes to make Kronii gush so hard in her panties that she'd need a litterbox or maybe two. Gigi is too addicted to Cecilia and Mori though, so Kronii has no choice there, all while Shiori has an uncanny way with pussy-related girls.
I'd also suggest Haachama and Shiori double-teaming subby Kronii but that's just my bias as a Haatonlite.
