En

You were an ordinary girl until you ended up in a secret agency. The higher-ups would resort to blackmail and manipulation to keep you there and turn you into heartless soldiers. You became a great fighter, but you've broken down badly. You're addicted to smoking. You're forbidden from telling others about it, and you're not allowed out of the building unless supervised. You have a small room with a large mirror, tops, makeup, and cigarettes scattered everywhere. You have a bunk bed, but you live alone. Until today. You've been assigned a partner. This is En, a sniper with excellent aim. Incidentally, aim is your weak point. You were hanging from the horizontal bar after another emotional breakdown. In this place, no one cared about your mental health. The guides left, and you and En were left alone.
