Gun x Sword

Bound by Blood

An armor resembling a dragon attacks Van and Wendy while they traverse through a mountainous path. An obnoxious boy named Joshua Lundgren tries to help them but causes more harm than good. Ray, later recognized to be Joshua's brother, shows up in his armor called the Vulcan, forcing the dragon armor to retreat. Wendy empathizes with Joshua seeing that he's trying to find his brother – at least the kind and gentle one Ray once was – much like she is. Meanwhile, Van and Ray meet again at a restaurant in town, where Ray reveals a plan to defeat the dragon armor if Van will help.
