Amy is the 16-year-old twin sister of Allen who shortly joins him on his adventure to protect the Solar Crystals. She is the Co-Guardian of Mayfield having earned her title by defeating countless monsters threatening the town. When it comes to physical strength, nobody in Mayfield even comes close to her, but unlike her brother she is not talented in magic.
Amy finds herself increasingly annoyed with her protective mother who does not believe a young girl should be putting herself through the kinds of danger Amy deals with everyday. Despite her father's protests, her mother has not budged her stance ever since Amy became a Guardian.
Amy and Allen have been very close since they born and continue to be. Individually they are a force to be reckoned with, but together they are nearly unstoppable. One thing that Amy longs for is to be able to travel the world. She has been stuck in Mayfield all her life, but the events that will soon occur may grant her desires.
