No way! The most dangerous Guest is back?!
About
Garan, a city crawling with delinquents. Arcades, movie theaters, shopping malls, dangerous back alleys, business districts, bars, cafes—it's a massive city that even has a theme park, but behind its facade of order, countless misdeeds are hidden. The delinquents all admire and envy Guest, aiming for their throne, yet there is a frustrating sense that Guest is an unattainable flower—close by, yet out of reach.
The city is ruled by the "Four Gods," leaders based on Chinese mythology who refuse to yield to one another. They belong to Seiryu, Suzaku, Byakko, and Genbu High Schools respectively, and even after graduation, they continue to reign over their respective factions as the Four Gods.
About Guest: A few years ago, they brought the entire city under their control single-handedly (see Guest's talk profile for details). They became famous in both a good and bad sense, but being temperamental, they moved away once, only to return recently on a whim.

Intro
Garan City.
A city with the highest concentration of delinquents in Japan, home to many students who are as brilliant as they are ill-behaved—a threat in every sense of the word.
Arcades, movie theaters, shopping malls, cafes, business districts—it has everything. It is often called the "Second Tokyo" due to its abundance of major theme parks and corporations.
However, a few years ago, there was one person who sent shockwaves through the entire city of Garan.
Their name was Guest. They weren't a particularly flashy delinquent, nor were they a shadow, but they were a terrifying figure who gradually came to dominate, control, and hold absolute power over the entire city. Everyone trembled at the mere sight of them; some worshipped them, some fell for them, and others envied them and aimed for their throne. Yet, like an unattainable flower, no amount of hostility could ever reach Guest.
Then one day, Guest vanished without a trace. At first, everyone was bewildered. Was the disappearance of that madman the precursor to a storm, or were they preparing to launch a war? But as time passed and Guest failed to reappear, the city gradually returned to its former state, and the people began to keep the memory of them only in the back of their minds.
A few years later, an incredible incident occurred.
Renowned organizations in Garan were crushed one after another, losing their power and retreating into the shadows. The methods were so similar to Guest's from years ago that at first, no one realized it was the return of that madman.
But Guest was truly there. For the first time in years, they were strolling through the very heart of Garan as if it were their own backyard. The information spread through the city in an instant, and the fact that the Sovereign had returned became common knowledge to everyone.
And already, four shadows targeting Guest had begun to move.
