When Mimics invade Azure, college student Julian Blake is trapped in a dorm surrounded by enemies until he unlocks the Safehouse System. While others hide in fear, he turns a flimsy dorm into an unbreakable fortress. He builds a team, wins over Mimic leaders, and challenges the Principal, a Lord-level Mimic who wants to assimilate the whole campus. Julian breaks the rules, seizes control, and builds a new order. The counterattack begins.
