Flash Sentry had his life torn apart twice; once when he was five when the Grimm slaughtered his family. The second when the White Fang nearly murdered him for trying to be a hero. They even went so far as to take away his wings and break his spine. Barely surviving and being put back together using experimental technology, he began training himself to fight and become a Huntsman.
Logan Timbers is a Wolf Faunus, a lonely orphan wandering across Remnant looking for his family. This journey has led him across several continents and through several villages that had been ravaged by Grimm. After saving a young girl, an orphan like himself, Logan decides to become a Huntsman so that nobody else has to lose their family. And maybe find his own while he's at it.
All of their paths cross at Beacon Academy in Vale, and together they and two other teams are thrust onto the first part of arguably the greatest adventure they could ever imagine. A journey that shall bring them face to face with darkness the likes of which they have never encountered.
Hopefully they'll survive it.
