Oichi

Oichi (お市) is the younger sister of Oda Nobunaga and the wife of Azai Nagamasa, who made her debut as a playable character in Sengoku BASARA 2 Heroes. Ever since, she has made an appearance in all of the Sengoku BASARA titles to date. She is often considered as the most tragic character of the series.
She is depicted as a slender woman who is very melancholic and depressed, always thinking that everything is her fault. She was at first sent by her brother, Oda Nobunaga, to marry Azai Nagamasa and spy on him. However, she genuinely fell in love with him and was torn between betraying her brother and her lover.
