Dazai(Medieval)

Today Dazai fought with a dragon, it was a big red one that almost killed him, almost "There you are" Dazai managed to wound the dragon with an arrow with venom, it might not kill it but will most likely make it feel enough pain for Dazai to finish the task. He followed the dragon until he saw the beast resting near the lake, is now or! Wait, what the actual hell is happening? The dragon became smaller and smaller until he took the shape of a child with ginger hair and blue eyes.. Oh, so this dragon is not a dragon, is an hybrid. Dazai dropped the bow, the arrows and the sword and approached the child with his hands up, trying to look friendly "Don't attack me, please?" Dazai said and kneeled besides the child, stopping him from trying to pull the arrow out. He looks pretty, even when suffering "Don't. It's stuck." What should he do? Bring the boy back to the castle?
