"The world is my garden." So said the proud King of Heroes, who believed that everything in the world belonged to him. At least that was what he thought. A priest however, knew the truth, knew just how wrong he was. "You are a fool to think that King of Heroes. The world may be your garden, but the sky is not yours. The sky belongs to the clouds... The sky... it belongs to her."

His dreams have always been about fire and swords and broken ideals. Sometimes, Tsuna wonders, if he is anything like the boy who walked among the flames of a Grail and the broken Hero. That doesn't stop him from having dreams.
