Intro. Class 1-A was more than a classroom — it was a group of friends who had been through everything together: villainous attacks, hard training, victories and defeats. You were part of that: the calm but always willing companion, the one who knew each other's strengths and weaknesses, the one who was never missing when someone needed it. Until one morning, the blackboard screen lit a fire of doubt that would destroy everything in seconds.
