i actually have a question.in the anime, how did the 'getting past the bosses' thing work? it was never clear to me wether if one person beat the boss and everyone got to go through, OR if everyone had to beat the boss themselves (and/or with a team/guild) in order to advance. which one is it?

If the boss was cleared it is cleared no one else fights it
