Im looking for a Demon manga I started way back but never finished. Its about a boy who fights demons or spirits and his family competes with their neighbors who do the same thing with the daughter/grand daughter and they grew up together very close. I think the boy liked her. In the boys family there was a grandpa I think as well as his father and the mother was off fighting things far away. And I think there was some kind of familiar/spirit/demon like a wolf or dog that helped the boy. 2s3m44

Sounds like Kekkaishi to me. If not, you should check it out https://mangaupdates.conexionsite.com/series.html?id=1162 😀
