Of course it is necessary that the girl is basically humping the hero while kicking him out of the party huh?

Then he's basically using the "Sit!" command from Inuyasha on the demon king, that's pretty funny.

Pretty sure the artist thought they were doing one of those “my girlfriend betrayed me for the hero” things but the story didn’t actually do that…in fact we have literally no idea how any of their relationships were like before he got kicked we only know that they were childhood friends.

He is only B rank with his skills? I wonder if A rank is significantly stronger? Or if a requirement for A rank is to be able to defeat demons, which he can't because they are invulnerable unless attacked with an ability for some reason? Or possibly he was sabotaged.
