Character Outline
In practice, she is effectively a prisoner within her own palace, which she dislikes. She saves Li Xingke from execution after he was caught giving medicine to a prisoner, and in return he promised to take her outside the palace walls. In the second season, she befriends Kaguya Sumeragi during their talks concerning the future of Area 11.

Second Season
She was to be married to Odysseus eu Britannia in a political marriage in the second season, and invites Kaguya to the ceremonial dinner the day before, who brings Zero along with her. The ceremony is interrupted by Li Xingke who instigates a coup d'état. However, as Xingke was about to reach her, she was held hostage by Zero, who retreated to the Black Knights' transport. During this time, Kaguya attempts to comfort her. While attempting to escape to India, the convoy is interrupted by Xingke in the Shenhu, who successfully captures the Guren and forces the Black Knights to retreat, hiding out in the Emperor's Tomb.

During the assault by the Federation and Britannian forces, Tianzi climbs onto the top of the Ikaruga, pleading for the conflict to stop, only for the High Eunuchs to respond with a hail of gunfire with the intent to kill her. Xingke attempts to use the Shenhu as a shield to protect her, but Zero intervenes in the{{ Shinkirō, protecting them both and exposing the High Eunuchs disregard for their country. The Britannian forces retreat, and Xingke assassinates the remaining Eunuchs. Diethard Reid suggests marrying her off to a Japanese to secure an alliance, but this is eventually disregarded. Tianzi is placed back in control of the Federation, making them Lelouch's first allies in his global alliance. She later became the Chinese representative of the newly formed United Federation of Nations, and was captured by Suzaku and held hostage with the other delegates on the Avalon. She is eventually rescued by Sayoko. However, once Lelouch defeats Schniezel, she and Xingke are both captured again after he takes control of Damocles and are slated for execution two months later along with both Black Knights and U.F.N. members, though Lelouch's death at the hands of Suzaku (as Zero) prompts their rescue by Cornelia.

She is last seen in the epilogue in a pair of photos: one where she is attending Kaname Ohgi and Villetta Nu's wedding and another where she is posing with Gino Weinberg.
