Sister of Oda Nobunaga and wife of Azai Nagamasa. Oichi was originally sent into the marriage as a spy for her brother, but she actually fell in love with Azai—a conflict that would haunt her throughout her life. She's known for her melancholic, guilt-ridden personality; fans often note how she blames herself for everything, no matter the circumstances.
Despite her delicate appearance, she has a darker side that emerges when pushed too far. Her weapon of choice is a double-bladed naginata that she can split apart and chain together, though in Sengoku BASARA 3 and the anime adaptation, she fights using shadowy dark energy instead.
