So I have been wondering, I can understand that the readers can see people enter the zone through the white lines that come out of their eyes, but how exactly is there any indication for the players? As soon as one person enters the zone, everyone thinks, yep, that guy has entered the zone. I can understand the generation of miracles as well as kagami and the serien coach know when people in the zone, but what methods do other people use to know?
This recent chapter makes me think was akashi the one who triggered everyone to become 'the generation of miracles (the sudden increase of abilities within the second->third year i think, not quite sure when their abilities started to bloom) like how his 'special generation of miracles ability' allows everyone else on his team to enter the zone.
