Jarrod

Jarrod is the host of Dai Shi

Jarrod was to be one of the three guardians of the chest holding the evil known as Dai Shi. But, when he showed himself to be uncaring to others and selfish, he was expelled, and Casey was given his place. However, when the enraged Jarrod attacked Master Mao with his Black Lion Animal Spirit, the chest was opened and Dai Shi was released. As he was making his way through the forest, Dai Shi caught up with him and possessed him. Currently, Dai Shi is using his body and his animal spirit as well.
