@vantasticmess and I had a Kuroshitsuji AU for SubKam that wasn’t really working well, so we recently decided to revamp it to the AU where Kamui is a bakeneko and makes a deal with post TB!Subaru where, if he doesn’t exorcise him Kamui will help Subaru “find the source of his suffering and end it”. To barely-just-got-his-cast-off Subaru, this sounds like a deal to help him find and kill Seishirou like he’d promised himself he would, but thank god for vague wording because it doesn’t really go like either of them expect it to.
Kamui is from the late Meiji/early Taishou period, and has been mostly in cat form for all that time, so he finds modern clothes needlessly difficult. He also hasn’t quite figured out how to lose the ears and tail in human form yet.
The first few days consist of him remaining in cat form and refusing to speak to Subaru when Subaru insists human souls are off the menu.
One of my fav Subkam headcanons is that Seals ship it. Subaru sits on Kamui’s bed, they’re holding hands and talking. Meanwhile Sorata and Yuzuriha are spying from window outside and being like YESSS!! my ship GOOO!
tbh my favorite horitsuba headcanon is that subaru and kamui are the president and vice president of the student council. watanuki is the treasurer and kazahaya and kobato are secretaries. no one accomplishes anything. fruits basket council hijinks ensue.
