It's said that people who can not see are called blind , but what if the sun disappeared? Would everyone be called blind? or lightless?

Bell mirai is a high school student, who's social abilities are as bad as 8 years old kid, our quite boy finds his peace playing games, unfortunately life has been the hardest game for him, so hard that he still doesn't know how to win in it, it's almost like he's in the "very hard" mood while the others are in the "easy mood".

Unable to progress in his life, a messenger was sent to him, an invite to SEP PUZZLE Game.

Strange yet weird message, will it teach bell how to win ?
