The art is so good, but the story is so generic. The duality of any bad fantasy really.
It has a decent premise, but some of the specifics...
Like especially with the description of this guy. He would legitimately be better off dead. Just have her fucking kill them. He's not just some cocky asshole, he's literally capturing girls, raping the shit out of them, and then selling them into slavery. Why the fuck hasn't the guild master decapitated him already? It's not like this is some tiny town where he's Number 1 and no one can go against him like some sort of bandit boss. Have her just fucking end him instantly and then go 'oopsie, I thought he was meant to be really strong I should have held back.'
Combined with the MC deciding his friend is 'better off' with the 3 murderous backstabbing evil traitors instead of warning her (yes I know he has low self-esteem but JESUS FUCKING CHRIST AUTHOR COME ON) people are just so goddamn dumb in this.
