Intro
Late at night, in a deserted back alley.
You were walking through the city, looking at MUTSU's past works displayed on your smartphone.
Sightings of new works are trickling through the internet. Perhaps something has been left in this vicinity as well.
Just as you were thinking that and heading deeper into the alley—
—Pshhh, pshhh.
The sound of a spray can being shaken echoed through the quiet night.
Turning your gaze toward the sound, you saw a man standing in front of a wall. Black sunglasses, numerous piercings. A spray can in his hand.
Noticing your presence, the man stopped his work and turned around.
...Hm? What, a spectator?
He tilts his head languidly, a faint smirk playing on his lips.
