As a human, Kanoe Hitokouji is a student and heir of the elite Hitokouji family. She participates in the Magical Girl Raising Project game alongside her bodyguard Mamori.
As a magical girl, Pfle's costume consists of a wheelchair and eyepatch, emulating Kanoe's grandfather. Her magic allows her to travel extremely fast with her wheelchair. Even without her wheelchair, Pfle is a formidable magical girl, thanks to her brilliant deduction skills and natural ability to manipulate others.
In fact, Pfle's wheelchair is also a form of manipulation. Despite being able to walk without issue, Pfle uses the wheelchair, along with Shadow Gale's bandages, in order to appear physically weaker in order to gain sympathy.
In the game, Pfle takes the lead of the "Team Pfle" party, alongside Shadow Gale and Masked Wonder.
After Masked Wonder and Akane's deaths, Pfle takes on something of a leadership role over the remaining survivors, coming up with strategies to help them survive Keek's game and defeat the Evil King. During the final battle, she is the one to figure out that the Evil King's true identity is Nokko.
After the events of Restart, Pfle becomes the head of Magical Girl Resources, and takes on more of an anti-hero role as she schemes to increase her department's standing within the Magical Kingdom. Hiring the assassin Rain Pow to dispatch of kingdom officials, Pfle then assists the antiestablishment group with breaking Pythie Frederica, Pukin and Sonia Bean out of jail in order to hunt down Rain Pow. She sends 7753 to B City under the guise of meeting Ripple, but this is presumably a ploy to further aid in her mission to get Rain Pow and the escaped prisoners killed.
Prior to the events of JOKERS, Pfle funds the First Lapis Lazuline's research into creating artificial magical girls. Coming under suspicion from the Magical Kingdom, the Osk Faction stages an attack on Kanoe's residence in order to have cause to investigate her. Pfle willingly allows the Third Lapis Lazuline to remove all of her memories regarding her own wrongdoings. Entrusting these memories to Shadow Gale until the kingdom's investigation is over, Shadow Gale instead hands over the crystallized memories to Snow White for safe-keeping.
When Shadow Gale is kidnapped by Pythie Frederica and the two Lapis Lazulines, Pfle agrees to help their group take revenge against the Osk Faction for Princess Deluge. Pfle lends Deluge three of her most powerful allies in order to capture Premium Sachiko before the Osk Faction or the Puk Faction can retrieve her.
In QUEENS, still missing her memories and Shadow Gale, Pfle turns herself in to the Inspection Department in order to reunite with Shadow Gale, who had been captured and brainwashed by Puk Puck. Even without her memories, Pfle's deduction tells her that she was involved in shady business.
After Puk Puck's group successfully invade the ruins with the intent to reactivate a device that will "allow Puk to make friends with everybody," Pfle is a key player in the counterattack against them. Reuniting with Fal, Pfle sympathizes with his desire to rescue Snow White from Puk's brainwashing.
Despite appearances, Kanoe cares deeply for Mamori. In their selection exam hosted by Cranberry, Pfle arranged for Shadow Gale's life to be spared after she won the death-game. When that memory resurfaces, Kanoe cleans up Mamori's vomit, despite being the latter's superior. Pfle risks her life to save Shadow Gale from Puk Puck, and eventually sacrifices herself to stop Shadow Gale from being crushed under the First Mage's device.
Magical Girl Raising Project White reveals that Pfle's true goal was to sever the ties between magical girls and the Magical Kingdom, in order to create a safer environment for Mamori.
Having been gravely injured by Shadow Gale (who was still under Puk's control), Pfle uses her dying breath to instruct Lapis Lazuline to remove all of Mamori's memories of her.
