A kind and honorable spirit, Kasumi is a compassionate young woman who tends to act before thinking. In spite of her skills as a kunoichi, she does not take any joy in fighting but can kill in cold blood should she deem it necessary. While she is friendly with Ryu, she and Ayane share a tense rivalry. Her sister's animosity for her has lessened in recent entries. In her first Warriors Orochi appearance, she also shares an affinity with Nemea, Diaochan, and Kunoichi.
