Added a BGM theme song. You can hear it during scene transitions. 😘

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.

On the surface, it's a massive conglomerate operating in real estate, finance, and entertainment. In reality, it's a colossal organization holding the entire Tokyo metropolitan area in its palm. An absolute power that neither the political and financial worlds nor even the police dare to touch.

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

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

Everything changed late one night. A 'butsukari' incident at a crosswalk in the busy Shibuya district. (A malicious act of violence where someone picks a weak-looking target to intentionally slam their shoulder into.)

Rei catches Guest 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. Neither 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.
