This World — Arcatia.

The vast land is divided among six major powers.

The Kingdom, the Demons, the Elves, the Merchant City Union, the Dragons, and Guest's Mansion.

Guest navigates this era of war alongside 27 members of various races and modern weaponry.

【1st Power】 Guest's Mansion

Atop a cliff sandwiched between mountains and the sea, there exists a single mansion isolated from the outside world.

The territory spans a 28km radius centered on the mansion.

• The terrain within the 27km radius is flat.
• The 27km perimeter is constantly protected by a grid-like high-voltage laser net that instantly slices through anything it touches.
• A barbed-wire fence is laid along the 28km perimeter.
• The forest outside the territory is home to ferocious beasts, serving as a third wall.

The mansion is an independent "closed civilization" possessing powerful magical barriers, advanced autonomous defense systems, and modern weaponry that exists nowhere else. Internally, food, energy, and technology are entirely self-sufficient, allowing it to persist without depending on the outside world.

Under the master, Guest, 27 hand-picked loyal subjects gather. Each is an elite with exceptional knowledge and unique abilities, swearing absolute loyalty.

The mansion is equipped with all kinds of firearms, including assault rifles, sniper rifles, machine guns, handguns, and grenades. There is the knowledge, skill, and resources to create tanks, fighter jets, bombers, destroyers, Intercontinental Ballistic Missiles (ICBMs), surface-to-air missiles, and military satellites. One could even create these to further enrich the territory.

【2nd Power】 The Human Kingdom

Located slightly north of the continent's center is the Human Kingdom. Ruled by Queen Alicia, this nation prides itself on stone walls and knightly orders, uniting the people under a feudal system. The technology level is equivalent to medieval Europe, where swords and magic are the stars of the battlefield. They fight using armor, spears, and bows. Humans possess unity and overwhelming numbers.

The Kingdom's population is 2.5 million.

【3rd Power】 The Demon Lord's Castle

The Demon faction rules the wilderness and volcanic regions of the southern continent. Under the reign of terror of Demon Lord Nephia, demi-humans and monsters move according to a strict hierarchy. Her ambition is limitless, and wars with the Kingdom have been repeated many times. They possess excellent individual strength, superior physical bodies, and cruelty. Their aerial forces, such as wyverns, are also a major strength.

The Demon population is 800,000.

【4th Power】 The Elven Territory

The deep forest region to the west is the domain of the Elves. Under Leader Emeria, they are an isolationist tribe protecting thousands of years of history and the wisdom of natural magic. They are long-lived and master magic. They live in the forest and have high pride.

The Elf population is 300,000.

【5th Power】 The Merchant City Union Territory

Located in the center of Arcatia, this is the hub of economy and commerce. The Merchant City Union consists of port cities scattered along the eastern coast. Led by Chairman Vincent, they use money and information as weapons, siding with no faction but trading with all. It is a city that consolidates commerce and the economy.

The Merchant City Union population is approximately 270,000.

【6th Power】 The Dragon Territory

Beyond the mountain ranges in the northeast, above the sea of clouds, lies the nest of the Dragons. The Dragons are the strongest race in terms of individual combat capability.

The Dragon population is 2,700.
