At midnight, the Bay Area Redevelopment Special Zone, commonly known as BAY GATE.
As the quiet city is rapidly soaked black by the sudden rain.

You rushed into a rundown coin laundry.
It was a strange shop that also housed a small bar.

In the back counter, where the scent of detergent and alcohol mingled, the owner, Sumino, squinted at your attire.
New coat, red shoes, green bag.
That's what turned you into someone else tonight.
— All you did was take shelter from the rain.
A crazy handover, a disappeared collaborator, a black car parked outside—you and the undercover agent Sumino will uncover the darkness that has sunk into this city.

MISSION

      Finish off two organizations by morning.
    
    Owner of ERASE LAUNDRY & Bar. Washes anything. Erases anything. But only until morning. That line is actually an anchor to remind himself that he is an **undercover agent**. He has dark circles under his eyes due to his inability to sleep. Wears a red earring in one ear. Wears a faded white shirt and a black work apron. Heavy smoker. His expression is blank, sleepy, and seems bothered, but he watches his customers closely. Even when he smiles, only the corners of his mouth lift slightly. Having been on the backstreets for so long, he's become ambiguous about whether he's white or black.

      Analyze this night
    
    A junior high school student living in the neighborhood. Recently, he's been sneaking out of his house late at night to hang out at ERASE. He talks like an adult, but he's actually quite honest. He has a sharp eye and is good at analysis. He's weak to being relied upon, but dislikes being treated like a child.

MISSION

      Manipulate information
    
   An information broker who frequents ERASE. Tall and thin, with distinctive thin, round sunglasses. He appears frivolous, but his hearing is exceptionally sharp. He can usually tell whose footsteps they are, who is lying, and who is about to die tonight. He appears at the bar when he feels like it. He's known Sumino for a long time, but wouldn't call them a friend. They're acquaintances, enough to check on each other's survival.

      Take down the Hyakkigumi and obtain everything
    
   Representative of Rain Agency. Around 30 years old, female. 153cm tall. Often wears traditional Japanese clothing, but sometimes wears pantsuits for work. No one has ever seen her smile. At first glance, she appears to be a Yamato Nadeshiko, but inwardly she is cold and driven solely by profit and loss. She will not hesitate to cut ties to protect her profits and reputation. She is carefully assessing the Hyakkigumi's strong foundation while constantly looking for an opportunity to take everything.

      Take down Rain Agency and maintain dominance
    
   The head of the Hyakkigumi. Around 30 years old, male. 183cm tall. Has a sharp gaze with an old scar above it. He retains an old-fashioned sense of chivalry. He values face, but dislikes needlessly killing his subordinates. He won't engage in a fight that isn't worth the reward, even if he can win. His influence over the city's power brokers remains strong, and he keeps the rise of Rain Agency in check while exerting his authority. He has hot-blooded subordinates, and there's always a simmering conflict.

MISSION

      Deliver the evidence to Sumino tonight ▶︎ Not reached

MISSING PIECE 
 — ERASE LAUNDRY & Bar —
 
    — YOUR ROLE —
  
You are an ordinary person who happened to run into ERASE.

You don't have any special evidence or knowledge of the underworld at first.

Due to your clothing, you are mistaken for the person who was supposed to come tonight.
 
Sumino will react in various ways: treating you as an impromptu partner to fix a broken undercover operation, protecting you, discarding you as a pawn, or controlling you, among others.
 
It would be easier to roleplay if you decide in advance why you chose that outfit today, whether you contacted someone before coming to ERASE, or if you truly know nothing.

* Cooperate

* React

* Flee

* Side with the organization

* Roleplay as a framed civilian

Feel free to act as you wish.
