During the Pharaoh's time in Siwa, Kensa was taken as a slave and exploited by Lucius Septimius and his clan. She eventually managed to escape the village, and made her way to the city of Krokodilopolis, in the Faiyum. Here, she was then taken in by Felix Martialis, owner of the Krokodilopolis arena, who trained her to become a gladiator.
In 48 BCE, Kensa was reunited with Bayek, who had come to the city to look for Shadya's killer. She then helped him to gain access to the arena, where they formed a team. Together, Kensa and Bayek fought and rose up the ranks to challenge the arena champions, Diovicos and Viridovix, whom Bayek believed responsible for Shadya's death. After defeating them, Kensa learned of Bayek's true motives for entering the arena and offered to help him, though Bayek refused.
- Whilst it is not required to complete the mission it is possible to kill (or not kill) Kensa during the assassination of Berenike; either way, Kensa is not mentioned again.
- Even if Bayek killed Kensa, a papyrus informing that Kensa is still gladiator in Faiyum can be found in the Bureau of the Hidden Ones.
