Yokohama at night, a blaze of lights and revelry.
Beneath the pitch-black night sky was a city shimmering with golden light. People of all kinds walked through this night metropolis, enjoying a different kind of indulgence than the daytime bustle.
Salarymen exhausted from the day walked in groups of two or three, leaving one tavern for the next. Provocatively dressed women stood in front of neon-lit establishments soliciting customers, their pungent perfume mixed with the smell of smoke detectable from afar. Dyed and tattooed street thugs, clutching the illicit money earned that morning, stepped into the houses of nightly pleasure.
Unlike most parts of the city that had long since fallen into darkness, only this area still radiated a distinct glow at night.
Brothels, casinos, nightclubs, and bars—places where people indulged in unrestrained entertainment—were all concentrated here.
If someone were to look down from high above, they would see them forming a circle, like a halo.
In the center of the halo were five towering spires, black as night, reaching into the clouds.
This was the headquarters of the Port Mafia, the ruler commanding the dark side of Yokohama.
Located in the absolute center of Yokohama City, these five pitch-black spires symbolize the five Executives holding power within the Port Mafia—the five people who rule over Yokohama.
Each tower belongs to one of the Port Mafia's Executives.
Standing atop the spire, one can overlook every area of the entire city, and no matter where one stands in Yokohama, these five towering buildings, like landmark structures, are immediately visible.
It is as if they are declaring sovereignty to everyone in the city, attracting all eyes.
Despite being a dark organization, their attitude is more arrogant than anyone else's; they seem not to care about the government's stance at all.
In fact, they really don't care.
The city of Yokohama is the most unique. Unlike other cities, Yokohama employs a management system called the "Three-Way Conflict" concept.
The Three-Way Conflict refers to [Daylight], [Night], and [Dusk].
The Special Ability Department manages [Daylight], exercising the official supreme authority as the nation's official Ability organization, managing all Ability Users nationwide, protecting citizens from the dangers brought by Ability-related incidents, and maintaining national order.
The Port Mafia dominates [Night]. Their shadows envelop the city, forcing citizens to live in fear, but simultaneously deterring other dark forces, making the predators lurking in the darkness retract their fangs and claws, maintaining peace in the shadows.
The Armed Detective Agency controls [Dusk], acting as arbitrators and assistants who walk in the gap between daylight and darkness, handling matters inconvenient for the government to interfere with, and helping both sides better protect the city's peace.
In this world where a power called Ability exists, every country has special methods and measures targeting Ability Users, which are necessary to maintain the safety of the country and its citizens. The Three-Way Conflict concept is the most suitable method for Yokohama among countless special measures.
In this city, the status of the three parties is indispensable.
It is precisely because of this that the Port Mafia so brazenly flaunts its existence.
"Among the three Ability organizations, only the Port Mafia is my best stage."
Strolling through the night streets filled with ambiguity and fantasy, Kurumi Tokisaki looked up, gazing at the five towering buildings, having already made her choice.
The Main Mission issued by the System requires Kurumi Tokisaki to become the terrifying Nightmare of Yokohama, which clearly cannot be achieved in a short time.
Therefore, Kurumi Tokisaki temporarily focused her attention on the Side Missions, which were easier to complete.
There are three Side Missions in total. The second Side Mission is to defeat Guild members, but she doesn't know if the Guild has appeared yet, so she has no chance to challenge them even if she wanted to. The third Side Mission is to hide her true identity as a visitor from another world. The only thing she can do is try her best not to expose her information, leaving the rest up to fate.
Therefore, after careful consideration, the only mission she could currently tackle was Side Mission One.
Choosing one organization to join among the Special Ability Department, the Armed Detective Agency, and the Port Mafia.
The Special Ability Department is a special institution under the government, an official organization specializing in handling Ability-related cases and Ability Users. Leaving aside whether Kurumi Tokisaki is qualified to join, the Main Mission issued by the System alone dictates that joining the Special Ability Department would be the most difficult choice.
Her Main Mission is to become a terrifying Murderous Demon in Yokohama, and one of the duties of the Special Ability Department is to arrest criminals who disturb public order and destroy peace. Naturally, she cannot throw herself into the government's headquarters.
The Armed Detective Agency is a neutral Ability organization in Yokohama, but while it is called neutral, it leans more toward lawful neutrality and has a very close relationship with the government.
Moreover, there are people there whose deductive abilities are monstrous. Although Kurumi Tokisaki has ways to join the Armed Detective Agency, she is not confident in hiding her identity as a visitor from another world among a group of great detectives.
Thus, the Port Mafia became the most suitable stage for her role-playing.
One is the leader of all local dark forces, and the other is the most wicked Spirit who has killed tens of thousands of people. Isn't that a perfect match?
Most importantly, if she could join the Port Mafia, it would be exceptionally useful for advancing the Main Mission.
However, joining the Port Mafia is by no means easy. At least with Kurumi Tokisaki's current identity, she cannot join through normal means.
Having just arrived in this world, with no identity, no records—an undocumented person—the Port Mafia would not allow such a suspicious individual to join.
Therefore, to join the Port Mafia, she needs to adopt slightly more extreme measures.
As Kurumi approached the Port Mafia headquarters, her school uniform instantly transformed into the Divine Spirit Dress: Third Dress.
The gentle and dignified young lady, at this moment, became a Spirit born from night and blood, gracefully stepping forward like a princess attending a banquet.
"Miss, this is not a place you should be."
The guard at the headquarters building saw Kurumi and hesitantly touched the pistol holstered at his waist, but ultimately chose a verbal warning: "If you come any closer, I'm afraid I'll have to take regrettable action."
"Is this the Port Mafia headquarters?"
"That's right."
"Then I've come to the right place."
Kurumi stopped not far from the guard and smiled slightly: "Could I ask you for a favor? I'd like to meet your organization's leader, Ōgai Mori."
"I apologize, but the Boss is not someone just anyone can meet."
Normally, when encountering someone who made such a request, the guard would have fired a warning shot to start driving them away, but facing such a beautiful girl, he patiently said, "Although I don't know who you are, if you wish to meet the Boss, please communicate with the Boss's Secretary first."
"Is that so? Then there's no other way."
Kurumi sighed regretfully, and under the guard's astonished gaze, slowly merged into her own shadow.
"Forgive my impoliteness, but I truly need to see him."
