This is Norin, a type of Deer Spirit creature, who is owned by Aira. Norin is a Class 3 creature, and his most used move is Yanera Force. He is also a well used creature, as a ride for Aira when needed.
The creature was humanoid, but it's body seemed to be made of woven wood. It's eyes were two glowing holes, and it's hair was a thick, elegant carpet of moss. It's hands were branches, leaves included, and it's feet were roots that twisted and dragged the thing along as smoothly as if it were walking.
