The Serpent Mage (Fairy Tail Fanfic)

Have you heard of Celestial Wizards? Yes! Have you heard of dragon slayers? Of course! But have you heard of serpent slayers? No? Why not? Well, that's probably due to the fact there barely are any. You see, the powerful serpents of old are very cautious of who they choose to teach. Sometimes they don't even take on a student. There are 5 we know of. Hikari, the light serpent. Dakun, the dark serpent. Mizuki, the water serpent. Kasani, the fire serpent. Finally, Dokoni, the poison serpent. This story is about a certain girl who was taught Poison Serpent Slayer magic.
