Kathryn Lapucelle

During the Arthur Tragedy, Kathryn Lapucelle was a Ten Knight of Eden, stationed in El Quixote to defend Kalar Forest and Kalar Village, with ten knights under her command. Despite her rank, the knights considered her to be inexperienced, and when they were attacked by overwhelming numbers of monsters, they put on a cruel act to get Kathryn to safety at any cost. By the time she managed to free herself, her detachment had been slaughtered, and she had inadvertently been named hero of the hour. After this misunderstanding and the death of Eden's ranking Zero Knights, Kathryn was promoted to Zero Knight, a title she resents. Ashamed and introverted, Kathryn managed to negotiate a position far from Eden,on the Lancelot-El Quixote border. There, she conducted research and created numerous inventions. Several years later, Kathryn's solitude was interrupted by her childhood friend, Riche Eden and Ramius Dreissen, as well as their husband, Aster. After helping them out during political crises caused by the Snake Crest in both Lancelot and El Quixote, Kathryn mistook Aster's aggressive flirting as a marriage proposal and confusedly accepted. The two of them sorted things out after a few comic mishaps, and got married consensually, after which Kathryn joined the others in their mission to destroy the Snake Crest.
