Varney

A black dragon who, like Letty, long ago sought out Diaria for advice on a new home and became his first dragon travelling companion. Differently from Letty though, he's a flashy troublemaker who prefers to be referred as the Mighty Black Dragon, a legendary harbinger of destruction. Fun Fact: His choice of Voice Actor pokes fun at the way he speaks like a mobster/gangster since Kenjiro Tsuda's two previous roles were gangster characters themselves - in My Hero Academia (Overhaul) and Immortal Tatsu (The Way of the Household Husband). Varney Appears in episode 8 & 9. (Sources: Dragon Goes House-Hunting Wiki and Wikipedia)
