of course! so basically:
sesshomaru has the appearance and mentality of a 19 year old. physically hes much older than that. but for all intents and purposes: he’s 19
one day he meets rin, an eight year old orphan who has been mauled and killed by wolves. he subsequently revives her with his sword tenseiga, and rin starts following him. sesshomaru lets this happen. therefore sesshomaru becomes her caretaker and her guardian
i want to say that rin travels with sesshomaru for the best part of a year, give or take. the point is that their established relationship becomes that of a child and guardian - some people see this as a father/daughter bond, others brother/sister.
unfortunately there are people who ship them romantically. they seem to think that its okay for “sesshomaru to wait until she’s older” but. if you’re an adult, who’s waiting for a child to grow up to an age of sexual maturity, that’s called grooming. thats predatory behaviour. he is looking at a child and deciding that at some point he will be interested in her sexually/romantically. i hope i dont have to explain why thats gross lol
so last year a sequel to inuyasha was released, hanyo no yashahime. and from what i can see, they’re basically gearing up to make sesshomaru and rin a couple officially, in canon. and even if they don’t, they’ve been baiting the audience with “will they, wont they” by dropping hints and leaving it open ended.
so if it does turn out to be canon, that sesshomaru waited for a child he took into his care to get old enough to have a sexual relationship with, and then had children with her? that’s fucked up and the series is fucking dead to me and a lot of other people
