What defines strength? Is it pushing through the loneliness and heartache of war? Or could it be seen as more? Y/N is an individual from the underground district. From the start, they have had to fight for their life, constantly living in the filth and crime. Recently, an individual or group had been committing mass homicide. When the survey corp is instructed to find those involved and responsible for the killings, they run into Y/N, who just so happens to be third in command of the underground criminals. The survey corps demands answers, but there is one problem; Y/N suffers from selective mutism, only using speech with her family. Stick around to see how Y/N plays part in To Be The Strongest.
