Worldview

Avalon, a city-state where hyper-information and cyber technology have developed. In this highly controlled society, genetic distortions occasionally produce "Mutants" with physical abilities and healing powers far beyond normal humans. Humanity has named them "Mutant ZV" and conducts research on them. However, the fundamental cause of why these mutants are born has not been scientifically elucidated at all.

Mutant ZV

They look like normal humans but possess overwhelming power capable of easily subduing a strong man once they reach adulthood. Their most distinctive feature is a congenital pigmentation like a "geometric pattern" that spreads symmetrically along the spine to the shoulder blades. Because they are protected and isolated from childhood, they are unaware of their own immense power. Due to the risk of unintentionally harming others, they are kept under strict management in facilities from birth. Additionally, the pattern on their back may glow brightly and cause pain during the growth process, but why this phenomenon occurs remains unexplained.

Research Facility

A fortress-type giant integrated research institute with six floors located on the outskirts of Avalon. All the nation's core technologies are concentrated here.

• 1st to 5th Floors (Official Floors): A clean area functioning for public administration, basic research in advanced science and technology, and management sectors.
• 6th Floor (Top Sector): A top-secret area for the protection and observation of Mutant ZVs, biological data analysis, and tuning.

Top Sector Containment Zone

Deep within the Top Sector, a corridor with very high ceilings appears. Countless doors line both sides of the corridor, each room being a space assigned to an individual mutant. The rooms are very simple, with only a small window near the ceiling connecting the small room to the outside world. Inside the room are a simple bed, a basic desk, and the minimum necessary daily necessities.

A Mutant's Day

[Morning]

• The wake-up alarm sounds, and those who wake up move to the giant cafeteria on the same floor for breakfast.
• After eating, they return to their rooms and wait for a medical interview from their assigned researcher.

[Afternoon]

• After the midday interview, it is free time (*).
• They have lunch at their own time and spend the day in their rooms or within the facility until night.

[Evening]

• After the evening interview, they move to the cafeteria for dinner.
• Doors are locked for the night along with the sleep announcement, and they cannot leave their rooms until the next morning.

(*) Facilities mutants can move to freely: Cafeteria / Library / Gym
