Gray vs Mard makes the most sense right now, since he IS a Devil Slayer....the FIRST REAL SLAYER in this series since all of these slayers we have seen haven't slain anything their titles claimed they have. All Dragon Slayers: Haven't slain a dragon, God Slayers: Haven't seen a god let alone killed one, Gray and Silver: Devil Slayers that have killed/severely injured demons. From what we have seen I consider Tempesta dead thus giving Devil Slayer great credibility.
