George

"He's a tree-spirit, they watch over the forests."

-Belldandy, Scarred Survivors Chapter 56; Green Trail Arc

Sasquatch. Or a similar Cryptoid. In reality a type of tree-spirit. He showed up one day as Keiichi and Belldandy were out camping during a cross-country trip back to Virginia. He was drawn to Belldandy's singing, and caught the goddess off guard. Then Belldandy decided to introduce him to Keiichi.

It did not go well.

Currently on a merry adventure with our two heroes as we speak.
