" This would make my mother proud "

This is Mizunos " final demon form " thinge. Her mother is a full demon, her father is a normal human. Mizuno achieved full control of her power as an adult. She's using it for fights - even thoug she's not fighting that much anymore as a proud mother of ( not retarded, disabled demon ) kidos. They're only half dogs but that's normal for Inuzukas (=^-ω-^=)
