Who is Kimo from Sacred Journey of the Peaceful Warrior and what is their importance?

Kimo is known as "Beer Belly" from the time of their first violent encounter in Kaunakakai until Dan and he make peace there a few days later, Kimo possesses the Spiritual Warrior's sense of not belonging to this world and having a special purpose. With no education or employment prospects, he and his brothers drink large amounts of beer and terrorize the town. Acting like a tough guy for his gang, Kimo grabs a flower out of Sachi's hair and taunts Dan to take it back from him. Dan pushes him and Kimo trips over a beer can. A storekeeper breaks it up, but Kimo vows, "Next time, bro', you dead meat."
