Albireo

"Women aren't something you can pluck lightly. They're something you offer yourself up with all your might to be engulfed by."

A young man with beautiful white wings that appears gallantly in front of Thumbelina.
He's actually the transformed form of the Ugly Duckling.
A smug gentleman who is a little overbearing. He calls himself the 'Sexy Attendant'.
He gives off a trivial impression, but he is actually good with the sword and has a helpful side.
