Bans lover or kings sister. Nobody cares about the latter, so let’s just stick with the former.

Elaine died and gave Ban immortality via the fountain of youth. In season 2, she returns as a reanimated corpse that dies again offscreen in the final episode of season 2. She also kisses Ban in the 2nd or 3rd opening of season 2 which is weird to see as she looks 10 and Ban looks 30. Ew. 

In terms of voice, I want something close to the dub of her. Failing that, do your best loli voice that isn’t too high pitched and painful to hear. Please. I have delicate eardrums.
