Joey's role in the anime is to be the supporting type of leader. While the main protagonist Alyssa is the one that gives out orders and leads the group in whichever path she chooses, Joey is the kind that would support the group socially. This means he would go out of his way to talk to each of his team mates one on one to find out if anything is wrong. He believes it is important to check up on every member to ensure that no one breaks down psychologically, especially in a heated battle or suspensful situation. Joey ensures that the Scarf Heroes and his own police squad function in a civil and stable manner.
Considering he has this stressful duty to keep up with everyone before himself, he can sometimes become hot-headed and thick-skinned. In the end, because of the morals he had learned in his old suburban town he will continue to work hard and do his best for his friends. One of his main concentration in life is to be sure that his lover, Sheepy, is happy, healthy, and successful in her endeavours as well.
