There's a character that shows off her cleavage to try to seduce the emperor.

Nothing too bad, occasional talk of seducing people and the characters go to a "brothel" nothing is shown, just clothed women being all over the male characters.

There's a few scenes where things are said or actions are taken out of context (the emperor touched the empresses chest and someone walked in/or comments about staying the night) overall just a bit of innuendos.
