Rise of the Common Devil [DXD FanFic]

Finding himself, as a servant in a manor, wasn't how Ryuu was expecting to spend his twilight years. But as one would expect from a former mercenary he adapted quickly to his new surroundings. It wasn't until he found out the name of the family he now serves, that he understood just how unusual his situation really is. ------------------------------------- A/N: I claim nothing aside from my OC(MC).
