Chacha

Lady Yodo (淀殿) is Hideyoshi's noble concubine and Hideyori's mother. Her mother is Oichi and her father is Nagamsa Azai. She is also known as Yodo-dono, Yodo-gimi, Azai Chacha, or Azai Kikuko.

Samurai Warriors
She is briefly mentioned by Hideyoshi during Nene's story in Samurai Warriors 2. In a letter, he doesn't want to burden his wife with the journey to the battlefield and requests her to send Chacha instead. Keeping an eye on him, Nene instead makes the trip and prevents the two from meeting. In the English script, she states that she fired all of his courtesans. This most likely includes Chacha as well.

Kessen
Lady Lodo acts as the figurative head of the Toyotomi family in Kessen. Using her womanly charms, she pleads several warlords to defend her home. These men include Mitsunari Ishida, Josui Kuroda, and Yukimura Sanada. An over-protective mother, she forbids her son from fighting at Osaka. If the Tokugawa forces win the battle, both Hideyori and her will commit suicide.

Saihai no Yukue
In Saihai no Yukue, Lady Yodo and the infant Hideyori act as victims to the conflict at Sekigahara. She pleads with Mitsunari to protect the Toyotomi family and settle the score with Ieyasu in battle. Additionally, she was the one who also suggested to make Garasha Hosokawa a hostage to gain Tadaoki's loyalty. She acts as a weak yet gentle voice of reason.

After Mitsunari wins the battle at Sekigahara, he learns from Ieyasu that Lady Yodo also had an audience with him. She requested for Ieyasu to attack Mitsunari, deeming the loyal subject to be the land's greatest threat. Suspicious of the conflicting stories, Mitsunari confronts Lady Yodo at Osaka Castle. When he corners her, she shows her true colors as a wicked and uncaring woman. She was the one who was responsible for Garasha's death and staged the entire war. In actuality, she doesn't care for Hideyoshi since he caused her mother's death.
