*stares* That is an awful idea you are awful I love it. :DDDDD
I think I’d want her to be closer in age to him than that – for all that she’s a youkai who’s hundreds of years old and knew him as a small child, their age difference has never really felt that great to me?
I could absolutely see her as an older student of the same master, though. (Maybe the different mask designs indicate some sort of “lineage”? tbh that probably makes more sense to a society of assassins than everyone having completely individualized masks, anyway.) Who was kind to him when he was younger, and who continues to be friendly and supportive, and who he looks up to and aspires to. Kind of a combination big sister / senpai figure.
(100% agree that either way, he thinks she has high expectations he’s not meeting. because this is Natori.)
