it was a pretty good chapter

it amazed me to see so many cursed seal prisoners

that also leads me into thinking, why didn't Oro give himself a cursed seal to make himself more powerful?

The mass of the cursed seal prisoners actually looked like a bunch of zombies or orcs from fiction films...sorta cheesy. I think the 1st level of cursed seal is actually pretty cool but the 2nd level of it makes it seem a bit unrealistic...(turning into monsters, etc.)
