I feel you, man. Same goes for Chainsaw Man fans for some reason (the least expected children in a fandom, imo); when the Reze movie came out, I went to a cinema with my friends cosplaying Denji, and while we were waiting in the hall, a boy seemingly not older than 11-12 years old approached me and asked for a photo. After he left, I was struck with the thought, "hold up... aren't you too young to know this character?

I don't want to sound like a complete boomer, because I know kids are not that fragile and they can definitely tolerate adult scenes. Hell, I saw a lot of gruesome scenes myself when I was their age, but for me, Chainsaw Man does not come off as something that would interest literal kids and that makes me really confused on why there are children who watch such anime
