Anime fluff/smut shots (practice book)

this book is to help me practice for actual books I want to make in the future, however, I am not currently confident enough in myself to make such works and is publishing/writing this as a trial run.

you can suggest characters within these animes for smut/fluff shots
Demon Slayer
My Hero Acidamia
Attack On Titan
Fairy Tail
and Seven Deadly Sins
