"Hey Anon, it's your brain here, I just had this cool idea for a picture! Come out and we can-"
"I HATE INPAINTING I HATE INPAINTING I HATE INPAINTING"

I'm not going to go over the process in all its minutia for every inpaint instance, so generally
1. I used fill at .99 (for whole picture) or .75 (for only masked), 'whole picture' imposes more limitations while 'only masked' is generally more detailed (good for smaller inpaints) but will greatly alter background and surrounding; both have uses
2. When I get a decent inpaint of what I'm aiming for I went over it with original/whole picture at .5 to fill in missing details 
3. Repeated the above at .1 to .3 depending on size/distance to round it out and blend it in
Sometimes steps 2 and/or 3 weren't necessary. Despite sounding straightforward each step required lots of rerolling and sometimes specific adjustments, and one or two zoom+enhances. Adetailer is mandatory for the smaller inpaints, I'm sure there's a way to do the same thing manually but I don't know it, that shit is magic as far as I'm concerned. The rest you can find in the metadata.

Went over onigiri at original low denoise (step not saved) and inpaint Neko 1 https://files.catbox.moe/papp59.png

Inpaint Neko 2 https://files.catbox.moe/yh3gqm.png

Manually draw lines back in https://files.catbox.moe/rnc7ir.png

Inpaint original low denoise to blend https://files.catbox.moe/9x8xyq.png

Inpaint Neko 3 (plus messed with hands but will fix those later) https://files.catbox.moe/wctvtd.png

Neko 4 https://files.catbox.moe/rp90lo.png

Touch up 4 (adetailer) and Neko 5 https://files.catbox.moe/eh78q5.png

Neko 6 https://files.catbox.moe/vegc0i.png

Neko 7 https://files.catbox.moe/jd5h0t.png

Enhance https://files.catbox.moe/taoeh6.png

Repeat for smoother background https://files.catbox.moe/66z836.png

Manually cut around Neko 6 because the background changed too much (ideally I'd just have a background that can blend, but by the time I realised my mistakes I was in too deep) https://files.catbox.moe/wimrgz.png

Use original low denoise to inpaint around Neko 6 outline to blend into background more https://files.catbox.moe/dx3fye.png

Touch up details (statue hands, Neko 2 foot) https://files.catbox.moe/w3y814.png

Layer everything together, lower opacity on background Nekos for ghost effect, blend where necessary (statue sleeve, white border from resizing), refer to finished product.
