Jace

A friendly spinxyn living in Catalis. They love to hang out at the colorful arcades downtown, and they may or may not have a reputation for dominating the high scores board on any and all rhythm games. His dream is to visit the high-tech city of New Celis and play their rhythm games.

While humans don't exist in Nephfei, Hatsune Miku does because I said so. And Jace is her number one fan.
