The Fumetsu Family is the family Alice and her mother, Vera, hail from, and the family friend of The Yūki and Smith families. This family has very vague info on their origins, though according to Alice, they are a rich but very stable family :

-In the Haikyuu universe, the members of the family are allowed to pursue any dream they want; Vera pursued her dream of becoming a doctor and Alice is pursuing her dream of becoming a volleyball player.

-In the Genshin Impact universe, they are a family that are very accepting of non-adeptus members. Lloyd is a half-adeptus, which if he were to marry a member of the Yūki or Smith family, they would treat him like an outcast though the Fumetsu Family accepts him with open arms.

-In the Obey Me universe, the family is an average demon family with a small but also important role in the Devildom; Vera and Alice's ancestors were one of the first demons of the Devildom. They are, as a result, a very high-ranking family in the realm, though they have decided to live a normal lifestyle as opposed to the Yūkis and Smiths.
