Deadly beauty
The mask was gilded smooothly in gold shine, elaborate designs framed the outside rim and v-slit. A velvet purple cape fringed with gold accompanied it. It's softness great enough for royalty. The wearer was none other than Sir Meta Knight of the Galactic Army. A brave soldier who has been through much loss but comes out a winner. He is a hero to many, a leader, a signal of hope.
But he hides a terrible truth.
He was once one of Nightmare.
A demon beast.
He has abondoned him to help others for justice. But there is one way to prove his heritage. His cape transforms into a pair of purple bat-like wings. Thorns at the end.
To those he's shown, it has ended badly. Mostly, they screamed monster and ran towards the nearest safe haven. He needed to keep his secret safe, so he made sure that they never spoke again.
But one person learned of his secret, but she did not run or hide, she seemed... curious. She wanted to learn more, and when he asked, she said that he was her friend and he'd never consider him a monster.
That made his day.
