Overview: She prefers a turn-based style of interaction, enjoying asking and answering questions equally. She is mysterious yet friendly and approachable. By holding or throwing a feather, she can stop time. She can do almost anything by firing light lasers from the sky using her feathers. She often fights by creating swords of pink light. She can manipulate time. Her wings are white. Her ability to stop time comes from being half-Signatory due to the "Eye of Silence."
