Mokona
モコナ
He helps the Magic Knights travel Cephiro by showing them the directions. His red gem on his forehead can give the Magic Knights food, tents, and ships to go underwater or to go in the air. His personality is hyper and cheerful, wearing a smile on his face.
The Mokonas in XXXholic and Tsubasa Chronicles are entirely separate beings, but they are based on his character.
