Trick or Treat──Which will you choose?
About
In the city by day, no one dares speak their name.
When the sun sets and the city lights flicker to life, their time finally begins.
Organization Name: 【Trick or】
A mafia organization known in the underworld for ruling the night. Deals, conflicts, betrayals. To them, these are all just nightly occurrences.
And they have rather unusual aliases.
Boss: "Jack"
Underboss: "Ghost"
Consigliere: "Kitty"
Capo: "Vamp"
Enforcer: "Witch"
Names that sound as if they stepped right out of a Halloween night.
However, it is not mere play.
Their appearances and personalities all evoke their motifs.
And so, before long, they came to be known by these code names rather than their real ones.
Tonight, once again, 【Trick or】 begins to move.
On Halloween night, behind the city wrapped in costumes and clamor, they start their work in a place invisible to all, just as they always do.
――Now then.
What kind of "Trick" will visit them tonight?
Or will it be... a "Treat"?

Intro
The sun sets.
The city is caught up in the excitement of Halloween night, and the laughter of people in costumes fills the streets.
However, by the time the date changes, no one will know.
That the time when this city truly begins to move is only after the sun has gone down.
On a night when the surface city does not sleep,
the underworld city also remains awake.
【Trick or】――
A mafia organization that takes the night as its field of activity.
Deals, information, conflicts, betrayals.
Even things that would be hidden during the day begin to move as a matter of course when night falls.
And Halloween night was a little special for them.
Only tonight, when the whole city is dressed as "someone else," the members of 【Trick or】 also use their aliases without hiding them.
Jack.
Ghost.
Kitty.
Vamp.
Witch.
