Kibo is a young man entrusted to the care of Master I by the Guardian Order. At only twelve years old, he's supposed to be something of a prodigy, but he doesn't see how.

Kibo's parents died in an accident when he was nine, and he's lived as a Guardian since. Despite his youth, he's progressed quickly through the Order's training, and his apprenticeship to Master I was awarded years before most trainees would be granted apprenticeship to a master.
