Wings of Glass 玻璃の羽

Mayfly, a girl with glass wings, is kidnapped by Ferace, a giant demon. Ferace rips off the wings that define her, but loses Mayfly to a cave. She is weak and scared. Dangers lie before and ahead of her. Be careful, stealthy, and smart to survive. She'll need to find her wings to get home. A big Thank You to DRWolf for voicing the main antagonist, and Naoya Sakamata for the Japanese Localization!
