Piper is the niece of General Ritsu Yamada and is also the cousin of Toshiko Yamada and she is a bad ass on the field but she has ADHD and anxiety and autism so sometimes she doesn't believe that she belongs on the field like her cousin or lead the Suberaith Squadron like her aunt but when Kyuserax attack a market place killing her parents, Piper join her aunt and cousin in the fight (thank to PopCross Studios for letting me write this story)
