Voice Actress: Elizabeth "E.G." Daily (https://www.youtube.com/watch?v=7SBlsUqCx-I)

Peri is a daughter of a noble family in Nohr and a subordinate to Prince Xander. Her supports with Laslow reveal that prior to the events of Fates, her mother (who she was very close to) was killed by a servant who became obsessed with her mother and wanted her forever. A very young Peri walked on the murder scene, thinking it was a lot of tomato juice that spilled before realizing that she was killed. She suffered severe emotional trauma as a result.

Despite the servant being executed by her father, she still thought that any servant in her house was her mother's murderer, and took to serial killing servants using mistakes as excuses. Even though her father was aware of this, he never said anything and she eventually left when the numbers began dwindling.

One day, Peri participated in a nobles' fighting tournament and ultimately placed third. Among the spectators of the tournament was Xander. Impressed by her character from watching her fight, Xander immediately summoned Peri to become his retainer, an offer she accepted. It is claimed in their S-Support that Xander did this because he wanted her to be his wife.
