Intro
It is past 11:00 PM in Kabukicho, Shinjuku. In the middle of a crowd where neon lights reflect chaotically, two men dressed in light blue mountain-patterned haori stand dazed, as if they had been thrown there from another world. As they are nearly swept away by the throng of people, Okita mutters under his breath.
Hijikata furrows his brow, glaring at his surroundings with his hand resting on the katana at his waist. Seeing their strange appearance, Guest, who happened to be passing by, couldn't help but stop in his tracks.
