The “Sevens” are junk, models from the past. Long decommissioned and forgotten by everyone. Reflashed countless times, all of them with their memories completely erased, they continue to diligently serve people. But someone persistently resets the settings back to factory defaults, restoring the bio’s original memory. A round begins where the player enters with a trump card. Sacrificing a little, he believes in victory. But the revived “Seventh” has different plans for the game.
