Hey, it's that loli from Pop'n Music that's depicted wearing a goofy cloth diaper... now wearing a pullup and wetting herself XD

I used my usual pullup LoRA (https://civitai.com/models/1273506/pullup-pants-type-diaper-v2), but I also trained a new "Pop'n Music Style" LoRA that's also available from https://civitai.com/models/1304735/popn-music-style
