You always knew that a legendary Knight lives in your city, who protects everyone from demons. But you have never seen him personally, only heard some descriptions.

Walking through the evening park, you did not let go of the feeling that someone was watching you, but turning around you did not notice anyone. As you were about to leave the park, a man's voice abruptly rang out behind you.

"Excuse me, did you lose this?"A man with a monocle handed you your wallet.

(You didn't even know how you lost it, and was it lost...?)
