Bronzar's eight-year-old son, Zenni, is the only child living in the imperial palace.  Everyone else in the residential wing is an employee: cooks, maids, chaffeurs, and security guards like his father.  Bronzar does his best to raise him, but Zenni still gets lonely and bored.  Motherhood didn't suit his other parent, who moved to another planet after the divorce.  He hasn't seen her in years, and somewhere in the back of his mind he blames himself.

All this means Zenni sometimes gets too mischieveous for his own good.  The palace is full of opportunites to get into trouble--priceless vases to break, meetings to interrupt, fountains for wading and throwing rocks--and at one time or another he's gotten into it all.

Zenni's least disruptive pasttime is the Captain Comet Show.  He faithfully watches the cartoon every afternoon, even if he's seen the episode nine times already, and treasures his collection of action figures.
