What characters would you like to see in a yandere story?

I'm going to write a story full of yandere!character x reader oneshots, and you, my lovely followers, are allowed to request characters and scenarios for it. Actually, I IMPLORE you to request.
Rules: NO lemons or limes. I'm not comfortable with writing these and Qfeast would probably take the story down if I did so.
DON'T ask for a character that I'm a. already doing or b. not in the slightest knowledge of them. Yes, I'll try to research them, but this will take lots of time and slow down the writing process.
PLEASE be kind when requesting, as in don't be all "HEY U I WANT BLABLABLAH NOW WHERE IS UT?!?!" Please just ask if I'll do a character and I'll tell you if I'll do them.
TRY to give a scenario for me to write with. For example, a good one would be something like 'Yandere-chan lost Senpai and Reder-chan comforts her" and I could write from that.

That is all, enjoy requesting!
