Prompt:

aris (winter) (blue archive), blue archive, winter clothes, brown hairband, earmuffs, official alternate hairstyle, single braid, blue scarf, plaid scarf, brown coat, fur-trimmed sleeves, brown mittens, white skirt, pleated skirt, black pantyhose, brown footwear, boots (Some tags can be removed if you don't want them appear)

Some Issues:

Sometimes it generates Kei (the pink eyes one). This can be reduced by adding <key> (blue archive) to negative prompt or adding aqua eyes to positive prompt.

A bow may appear on her braid for some checkpoints. This can be solved by adding hair tie to positive prompt.
