Erii Uesugi

The Clan Chief of Uesugi, one of Hydra's three inner clans, the younger sister of Chisei Gen. Just like a charming princess from the 18th century, she is slim and has an exquisite and elegant face, and is pure, naive, and lacks common sense like a cute cat that is defenseless for males. She loves warmth, freedom, this world, and the boy that filled up her whole world.
