Starlos is a old friend of Ceroba and he runs the Fistey Five
Ceroba is 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... he is now in a death bed, Ceroba accompanying him
Kanako was listening in to their conversation in secret and learned that she's maybe the reason why her dad overworked himself to death
