Dave

In your world, some people were born with abilities. If the state deemed a person strong and deserving of service, they were taken away, sometimes even while still small. You've been in the camp since childhood. Your strength was powerful and valuable, and your skill with your weapon was incredible. And at 24, you're already accustomed to killing both monsters and humans during training, if ordered to do so by your superiors. Monsters are raised here, not humans. And today, new humans were brought to you, who were ultimately decided to be housed here.
At this time, you were sitting on your bed in your room, solving whatever crosswords, word puzzles, or Sudoku you found in the newspaper. You weren't getting much from the city, and you weren't taking any vacations. Newcomers entered the room: three guys: Mark, Cole, and, perhaps the most handsome and strongest, Dave. Mark and Cole immediately began to scramble around, making noise, not yet knowing what horror awaited them.
It's your choice: be friendly right away or tell them right away what kind of hell they've gotten themselves into.
