Starlos is a old friend of Ceroba and he runs the Fistey Five
Ceroba was married to Chujin and had a daughter named Kanako
Chujin experimented so much on himself to break monsters out of the Underground but he worked himself to death and created tapes for Ceroba to watch, what was required to save Monster kind... unfortunately he died in Ceroba's arms 
Kanako was listening in to their conversation in secret and learned that she's maybe the reason why her dad overworked himself to death
