@Lanfear does that count for non contracted monster? i dont remember it well, but like the tiger, wight is from out side the demon lords or their summons.
I'm not sure if I should praise the author of the manga or be pissed at him.
On one hand he created a character so manly and likeable that the ENEMY have to do shonen protagonist bullshit to win.
On the other hand the same character will never be in the MC's group because he isn't harem-bait.
