Yuzuha Hitachiin is the mother of Hikaru and Kaoru Hitachiin. Yuzuha appears as a supporting character in the manga only, though the twins mention her in the anime. Yuzuha heads her own high-end fashion company, and her sons take after her. She loves her boys, but she tends to tease them by saying she can't tell them apart when she actually can. Her husband works at a software company and he took her family name when they married.
