EagleOnyx is playing with his new friend Akari. For those who don't know the story, Onyx was exploring some ruins and noticed the little wisp following him. He didn't pay it any mind at first, leaving the creature be. It wasn't until that it followed him out of the ruins that he decided to keep it. The wisp made no protest and Onyx made a little cage in the shape of a lantern for him to live in.

Much thanks to  TinyCactus for this! http://www.katoartonline.com/

A little side note: Akari means "light" in Japanese.
