Oichi

Oichi (お市) is one of the starting characters in Samurai Warriors. She is Nobunaga's younger sister and Nagamasa's wife. Historically, she later becomes Katsuie's wife, which is implied to also occur in Samurai Warriors 2: Xtreme Legends. In the first game, she is 15 years old.

Samurai Warriors
In Samurai Warriors, Oichi is a peppy and optimistic teenager who loves the ones close to her. She starts her story by fighting on her brother's side. When the Azai and Asakura betray Nobunaga, Oichi fights with her husband. She believes that there is a peaceful way to end their dispute and seeks her mentor, No, for advice. In her lower path story, she is convinced that the only way to end the violence is to kill her brother. She succeeds in this task and later destroys the remaining troops lead by No. She continues fighting alongside her husband to honor them.

Her true ending has her invading Azuchi Castle in an attempt to convince her brother to make peace. However, when she reaches the top floor, she meets Mitsuhide who informs her of his plans to betray Nobunaga. With Nagamasa's help, she saves her brother's life at Honnoji. After a brief exchange of apologies, the men reconcile.

In Samurai Warriors 2, she is a strong believer of fate and destiny. Her story starts with her happily married with Nagamasa. When her husband is later cornered by the Oda forces, he tells her to return to Nobunaga. Knowing that he wants to ensure her safety, Oichi obliges and is ironically ordered to lead the final assault against Nagamasa. She is forced to kill him in battle and tearfully bids her loved one farewell.

Oichi's dream stage is a humorous beauty competition that involves all the women (and Ranmaru) in the game. She is challenged by No to prove her beauty in battle.

Warriors Orochi
In both games, Oichi is faithfully following Nagamasa.

Kessen
Oichi is a non-playable character in Kessen III. She is a timid and beautiful woman who is admired by many of Nobunaga's men. After Nagamasa's death, she later tends to Kicho's wounds after Honnoji. She can be a playable unit if the game is on Expert difficulty.

Development
Her youthful debut was done to create an idol character for the series. Key words to help her design were rabbit, sailor outfit, and fox. To better fit the themes set in Samurai Warriors 2, she was given a revamp that emphasizes maturity. Since her role in this game is to be the bridge between both clans, the Azai and Oda crests also don her outfit.
