It's funny how he calls out the "slave harem" considering that the Spear Hero officially has a harem for his party and gets away with it both in and out of universe.

>revenge against a lady
revenge against the king, his daughter and the whole kingdom who treats him like shit because he's the shield hero
>harem of slave women
harem made of a slave he bought out of desperation of not being able to trust anybody, and two other people who aren't slaves

Context. It is important.
