we DO know what his name is… it’s kangjin, the revengers director, remember..? he’s not considered a 5th survivor because he never made it OUT of the dungeon, and the only people that know what happened are both dead and heavily traumatised to the point she can’t recall the memory. however, my theory is that he went in the black s portal alone. anyways, remember to properly read!
it's stated that they're 'missing', not 'dead' and we don't even know their name afaik... why are they mentioned so little? it's weird how often people forgot they exist
