We really didn't need multiple chapters explaining how Mirio was actually strong.
They gave us enough hints throughout the story, including the part of Soil having to constantly fight all the monsters of the kingdom.
I just checked the previous version, and it does seem very out of place to suddenly have him fucking a random shopkeeper in front of her.
Should've probably kept her in there as the shopkeeper, though.
Also, it feels like it's missing a chapter between 5 and 6.
