Prob Mia I feel, she basically just wants to spend her life writing music and eating burgers, and with such a sedentary life style, she's perfect to end up as a blob + she'll just kinda accept her gassiness/disgusting habits, only commenting if someone nearby says anything about it

"Don't be a baby, it's not that gross" she says, as if she didn't just unleash a rancid fart that lasted for a whole 30 seconds + raise the room temperature by 10 degrees...

But also close in the rankings it's Shizuku (who would actively be into the slob aspect/horny AF for her braps), Yoshiko (same as Shizu, but prob unlucky enough to die from health problems), and both Sumire and Natsuki (I feel like they would be fat slobs for the views/content)
