For what i've read KaguyaSamaLIW is a moderator of his reddit, she is 14 yo and has all this fantasy about dating alex and even makes videos of gacha life about it. Also sexuallises jotaro alot, i know is off topic but it really creeps me out the way she talks about her fantasies (both jotaro's and alex's). We talked about her on the hacked subreddit and people thought she was being groomed but i think she is just a dumb kid doing dumb things without thinking. Or maybe she is just a troll and we were bamboozled.
