There are moments inside the training room where characters have to remove their clothes for the trainer to examine their muscular growth. The scenes somewhat censored.
Pervy men touch teenaged girls and children inappropriately. The girls are sex slaves and are sold for a night to be raped frequently. No rape is shown, but heavily implied by dialogue and the reaction of the girls as they return home and when they leave, looking distraught in elaborate skimpy clothing.
Lugh's mother offers to set up an arranged marriage for Lugh and he politely declines. Tarte is very jealous and makes it known.
In episode 10, Lugh takes a bath with a girl. His bare butt is shown. Her breasts are fogged over by steam so you don't see the sensitive parts but you still see pretty much everything.
Some romance between characters. Show is somewhat of a harem, but not too bad. No sex at all, although some sexual references, etc.
