(Empowered) Rainbow-winged Sylvia

Lore
The innumerable monsters of the castle seemed to deny Sylvia any hope of reconciliation. Her mind was mired in regret, yet she knew there was only one thing she could do. She turned her sword towards the monsters, vowing to "rescue" Irene and protect her henceforth. Releasing seven colors of magic from her spread wings, each and every abomination was completely vaporized. With her two companions at her back, she charged into the Sky Castle.
