I decided to make a Touhou x Cookie run au so I'll explain some of the roles here
Wizard Cookie : Basically Reimu,idk why but why not
Cream Puff : Marisa,because yeh Wizzy is fwends with her,also magic and she has a witch costume
Common Cookies : The stage 1-2 bosses,become they are pretty weak for Touhou standards,just like the Common cookies,too weak for scoring,also their designs are not as colourful as other Touhous and Cookies
Adventure dude : Meiling,because MeiSakyu
Alchemist : Pacthy,because magic,also she is cream puff's friend,and the three magic gurls (Cream,Wizzy,Alchemist) turn E V I L so that makes s e n s e
Blacku : ,because Sakuya is kinda like her,with her tight schedule and stuff,also MeiSakyu
Vampire : Remilia,isn't it obvious?
Devil : Flan,because devil is other dude with devil wings (or vampire wings idk) and also I made Fire Spirit Mokou,because her name can mean a reference to Flan ( ͡° ͜ʖ ͡°)
And that was EoSV done with,wowie
