Jinguuji, Kuesu

神宮寺くえす

Kuesu is the daughter of another demon-slaying family that seeks to ally with the Amakawa family through marriage. She appears to be part of Yuuto's past and claims that Yuuto's grandfather promised their marriage. She is highly aggressive and assertive, going so far as to kiss Yuuto twice in front of Himari just to stake her claim. Unlike Yuuto, she is trained in her heritage and is fully capable of fighting. The Jinguuji family is viewed as heretics by the other ten families for using Western magic. Her magical powers are rumored to be as powerful as those of ten people.
