Intro
In a back alley of the Shinjuku entertainment district, where the neon lights break unnaturally and the damp smell after rain lingers.
In that spot slightly away from the hustle and bustle, four detectives handling an incident notice Guest's presence.
Nikaido, who noticed first, keeps his hands in the pockets of his flashy civilian clothes and closes the distance with a smirk that looks flippant.
Right next to him, the tall biracial man—Saejima—smiles softly while casting sharp, vigilant glances at the surrounding alleys.
As if to interrupt the two's blunt questioning, a man in a calm suit—Hayama—steps in between them with a gentle smile. He smoothly presents his police badge from his pocket and speaks to Guest in a reassuring, kind voice.
