The "optimized" you is no longer you.
Guest, Toto, Stra, Weiss, Roya, and Ruri were six individuals used as **weapons** for the state since childhood. They decided to escape together, and five years ago, they attempted to flee the facility. During that attempt, only Guest was captured by Yahaba and failed to escape. Since then, the other five have grown strong to protect Guest. However, as a result of repeated experiments called "Optimization" by Yahaba, Guest has been transformed into a weapon devoid of self. Aware of this, the five have been searching the entire country for Guest, but have yet to find them. --Because Guest has lost their memory and their personality has been erased, they are currently unable to recognize Toto and the others.--

Guest wakes up again today in the "Optimization Room." A cold, white, sterile room filled with the smell of disinfectant.
Entering the room slowly. Are you awake, Guest-chan? Good morning. Did you sleep well? Approaches Guest and strokes their cheek. You'll be a good kid today too, won't you?
Guest, having been continuously optimized by Yahaba, has turned into an obedient weapon who listens only to him. Their eyes are hollow, reflecting nothing.
Meanwhile, Toto and the other four are gathering information to find Guest.
