Natsu; Gajeel? Juvia?

Phantom Lord's Ace-in-the-Hole, Kurogane Gajeel* ended up joining Fairy Tail after Phantom was dismantled, and he's proved to be a loyal member of the guild up until this point. Gajeel is a Dragon Slayer like Natsu. Juvia, another S-Class mage, former member of the Phantom's acclaimed Element 4 also joined Fairy Tail after stalking Gray Fullbuster for a short time. As a Water Mage, Juvia is a polar opposite to Natsu with his Fire Dragon Slayer. Still, nothing has helped to fully iron out relationships between the former Phantoms and the Fairies.
