If you don't mind ocs, I've got a couple! I'm not as confident with my canon characters right now but if you give me a bit of time I could pull one or two out of my muselist.

Mostly I have one shounen protag heroine and a (very very) old and patient man (not human)! Maybe we could have one of my dudes and one of your dudes work together in a jamjar setting (go on a mission together)?
