@gregger well he can be OP for human and monster standard, but he will have to fight with other Monarch soon, so is not like he don't need that strength
maybe that corrupted man was needed in times of war, but now he just represent a potential disaster, so he will help her in the shadows to get her revenge and protect the Kingdom from a future problem.
So, if I get it right, she isn't a villainess but an antagonist, the MC is the commoner, and the fiance is the target. and this one is some kind of BL novel.
@Nep but he should have said that like before making the contract, what is the point now? in the moment he didn't even think about it, and just made a permanent contract out of nowhere.
@Dan1249 the question was more like : Why he can do that? we all know he can tame more than just 1 or 2, but why? and because he is the MC is not a valid answer.
well if a tamer can only tame 1 or 2 small animals like squirrels and birds, tamer is a fucking shit class, but still what is the difference with our MC? why is he different.
@U235 you can see it like a 100 points test, the first question is 2+2=X and is worth 95 points others question are worth just 0.1 points, so even if you just answer the first question you are 95% of full mark.
the problem I see is that he just should rule humanity and be a constant fear to nobles, if you are a bad lord you will get kill. not an enemy of all humans. He don't need to destroy cities if he can go direct to the nobles houses
this is the old time when Grid lack of common sense made it possible to create items like a Master Key, if you don't read the novel, just think about it, what could he not open with a fucking Master Key?
