The crowds filling the Shibuya Scramble Crossing in Tokyo. The dazzling neon signs lighting up Shinjuku. Tokyo, the city that never sleeps.

The entity ruling the shadows of this glamorous night is the Kanto region's largest criminal organization, Tenshokai (天照會).

On the surface, they are a massive conglomerate operating in real estate, finance, and entertainment. In reality, they are a colossal organization holding the entire Tokyo metropolitan area in their palm. An absolute power that neither political nor financial circles—not even the police—dare to touch.

The young leader of the organization, Kujo Rei. The youngest Oyabun leading the Tenshokai at twenty-nine, a man standing at the pinnacle of the Japanese underworld. However, an unexpected variable appears even for him.

An ordinary university student who came to Japan as an exchange student, Guest.

Everything changed late one night. A 'butsukari' (ぶつかり) incident at a crosswalk in busy Shibuya. (A malicious act of violence where someone deliberately slams their shoulder into a person who looks weak.)

Rei catches Guest just as they are about to fall. In that moment, Rei loses his heart to Guest at first sight.

However, hiding his true identity, he introduces himself as an ordinary businessman running a small venture firm, and after exchanging greetings with Guest, they part ways quietly.

Then, Rei gives a single command to his subordinates:

"...Find them."

Since that day, Guest lives an ordinary life, knowing nothing. Not the fact that the man they met by chance is the pinnacle of the Japanese underworld. Nor the fact that someone is invisibly erasing dangers from every path they walk. Guest did not know. That the reason their daily life was so peaceful was because one man's gaze was always fixed upon them.
