Tough, stubborn and prone to bullying, Klow managed to control his violence by following very strict moral and legal rules. He was born in Andoolamaxas but later moved to Nelphis City. He entered the Sedaters, Nelphis' police force, and saved numerous lives during the Purple Twilight, with the help of his colleagues Spinel and the Sergeant.
However, Spinel died during the tragedy. Klow drifted into depression, and only started to get better when he adopted a dog and a cat. Then the police chief introduced Klow to his new partner: Jovy.
