After the failed rebellion, Chiba was arrested along with the other members of the Black Knights. To draw out Zero,Gilbert G.P. Guilford threatens to publicly execute all of the Black Knights. However, Zero does come, but manages to free them all. Because of Zero's earlier abandonment, Chiba has a harder time to trust Zero, but because of Tohdoh still follows under his command. She is later seen during the assault on a Britannian aerial transport of Viceroy Nunnally to kidnap her. She witnesses when Kallen falls off the airship and tells her to pull the ejection seat. Following that, Chiba is caught by the Mordred and ejects right before her Gekka is destroyed.

During the time when the Black Knights are in the Chinese Federation, Chiba obtains the knightmare, Akatsuki Command Model Zikisan to replace her Gekka and to fight against the Chinese Federation forces with it. During the Battle at Xiaopei, Chiba and Asahina were able to ambush the Chinese Federation forces. However, after the Shen-Hu makes an appearance both her and Asahina are overwhelmed by its power and she watches helplessly as Kallen is taken prison. She regroups with the remaining Black Knights at the Mausoleum of Eighty-Eight Emperors where another battle ensues between the Black Knights and the united forces of the Holy Britannian Empire and the Chinese Federation. She along with Tohdoh and Asahina are left in charge of destroying the air units as well as engaging in battle with the Knights of the Round. During the battle, Chiba along with C.C. both strike the Mordred and Asahina is able to follow up by damaging the Mordred's Float System. The battle ends after the High Eunuchs are exposed and the Britannian forces retreat.

Before the meeting of the U.F.N., everybody is preparing. Chiba is seen putting on make-up for Tohdoh and was on her way to ask Tohdoh a question hinting on how their relationship is, but Ohgi arrives and Tohdoh leaves while Chiba states that "she was to slow." She later appears in the Second Assault on Tokyo Settlement, under the command of Tohdoh. As the Gefjun Disturbers disable all 5th generation and lower Knightmares, she along with Asahina and Tohdoh try to achieve air superiority over the Britannian government building by destroying the Britannian forces that pilot 6th generation and above Knightmares. When Kallen was set free and was piloting her Guren S.E.I.T.E.N. Eight Elements, she rammed through David T. Darlton's Gareth allowing an opening for Chiba to finish him off. After learning the truth of Zero's identity and his geass power, she joins the other leaders of the Black Knights and betrays Zero (expressing particular horror upon hearing Lelouch's confession about his role in the SAZ massacre).
