@DoubleNwah It's easy to explain really, he's the son of someone they crushed. They don't want to have anything to do with him or be associated with his family. To them, he's a weakling and should stay where he belong: below the Shinomiyas. That's why they aren't saying anything yet about Kaguya's ralationship but if Miyuki were to show himself to the head, he would be obliterated.
