The minotaur is Minokichi. His name used to be Gobukichi back when he was the dumb goblin shield bearer Rou was using as a lackey that became his best friend.
In all honesty, Rou is kinda sweet to his people for a sentient eating monster.
Also, the scene where he said "so we had some fun" my only thought was "You did, maybe".

She's in the very last panel of 14, but actually meets Rou in the 15th. She's actually what jump started Rou's harem, finally. The girls got jealous that he got his rocks off with the dryad, then started going after him seriously.

The Minotaur is one of the original 3 goblins this story started with. He just evolved into a minotaur, just like the female goblin evolved into a vampire.
@monkey123 Cait Sith are Celtic spirits and are a part of Scottish mythology. Just like Brownies, Maggy Moulach, or more recently the Loch Ness Monster. So yeah, they predate Fairy Tail by quite a bit. I'm pretty sure most people first learned of them from Final Fantasy though.
