Puck

Puck is an artificial spirit crafted by the Witch of Greed, Echidna, whose catastrophic latent power has earned him the fearsome title of 'Beast of the End.' In everyday life, he takes the form of an adorably small cat, devoting himself entirely to Emilia's protection and well-being — a bond that transcends a mere contract and resembles that of a true family. As Season 2 unfolds, faced with the grueling Trials of the Sanctuary and the deeply buried sealed memories haunting Emilia, Puck makes the resolute decision to voluntarily dissolve their pact, channeling his guardian's determination to light the way for the one he cherishes most.
