Rainy night, Tokyo pier. Belmod had just completed an assassination and was about to leave when he heard a faint cry. Behind the container, a baby boy was abandoned in the cold wind, wrapped in a thin blanket, his little face turned blue from the cold. There was a piece of paper stuffed in the swaddling clothes, with only one name written on it: "Nagaze Hai", and a strange silver pendant around her neck - in the shape of half a broken wing. "Poor little thing," Belmode sighed softly, reaching out and caressing the baby's cold cheek, "Are you abandoned by this world like us?" Finally, she picked up the baby and disappeared into the night. Kyogoku looked at Nagasawa Kai seriously: "Since you are Sonoko's brother, you are also the person I want to protect." Kai looked at the people in front of him and finally showed a sincere smile. This was the first time in his life that he felt the warmth from others. Outside the window, fine snow began to fall in the Tokyo night sky, as if it wanted to wash away all sins and the past. At the end of the hospital corridor, a blond figure quietly watched all this, with an unreadable smile on his lips.
