Don't get fooled by the name, he is a boy. He was like a father next to Gajeel. I love them both. Even if I enharted my Solid Iron Dragon slayer from my parents, it was only a small portion. Serenity helped me exploit it to its full power. Of course he left, like every other dragon, but I don't hold a grudge, he left me because he had to. I miss him so much!

"Serenity please come back. I miss you."
