First of all, let me tell you that the 3 episode rule does not apply to this, you'll think that the samurai guy from the 1st episode is the MC??? Nope, EVERYONE is the MC, that's why this has like 4 episodes of character introduction because it makes you choose to root for someone who you think deserves to be the Hero. This is a battle royale with no MC. So abolish all the thought that you will be following someone's journey because you'll be following EVERYONE'S journey. It might be confusing at first, even I read a wiki page just to know who's onthe side of who in the war, but after you get through that, this is actually good.
