Lights flicker and flutes whistle!

This rarely happens to the people of Dark City, because the flute means martial law!

Ever since the Dark City was founded, the martial law has averaged out, not even once a year! uuuuuuuuuuu

This means that something big is going to happen tonight! uuuuuuuuuuu

When the shrill flute sounded, the neon lights in the neighborhood began to go out one after another! uuuuuuuuuuuu

Many businesses are closed, and the mercenaries who have nowhere to go can only leave the pleasure-seeking places immediately and return to their homes honestly.

The Dark City has very strict rules. They can't even roam the streets during martial law!...
