Vandal Hearts II - Tenjou no Mon Japan

Joshua's day started out simple enough. Climb up on a roof to catch a butterfly for Adele. Once he actually catches it, he promptly falls off the roof. That would be the beginning of the end. His stepsister Rosaly comes running over to say a stranger is being attacked in the field. With the help of his two friends Yuri and Clive, they save the stranger and bring him back to the village so the doctor can treat his wounds. Little do they know, this act of kindness will change their lives forever, for this is no ordinary stranger.
