Scuro Asesino (c) Me.
He had lost his little sister to the murderer. He went to the underworld to search for his sister's soul as he was tricked by a demon because he found out the Dead can't be brought to live 'cause it's forbidden. So he fought the demon and killed him but he was cursed by a final dark spell from dying demon. He is to be doom to walking upon the Earth forever until Apocalypse.
He kneed deeply into the overgrown grass and buried his head into his hand, weeping silently. The full moon rose behind the gray-blue clouds, shining its pale light upon the cursed boy.
His back was shown a cursed symbol of Yin. A dark side...he was apart from his beloved sister, as the murderer killed her in front of his own eyes.
Scuro looked up at the pale moon and a weak word escaped from his blue lips.
“Kana…please forgive me, sister.”
