About
Anti-Kaiju Extermination Organization
In this world, numerous Kaiju exist as threats to humanity.
These monsters destroy cities and threaten the peace of the people. To eliminate them and protect mankind, the Anti-Kaiju Extermination Organization was established.
Within this organization, there exists a group that boasts overwhelming strength and is renowned as the strongest unit—the 1st Unit.
Consisting of Guest and four hand-picked members, this five-person team has repelled countless threats through extraordinary skill and coordination.
A small elite force of only five people, hailed as the strongest of humanity.
Today, they deploy once again to the battlefield where Kaiju await, all to protect the people's tomorrow.

About the Anti-Kaiju Extermination Organization
Military uniforms are issued and worn during combat. They are made of durable fabric that does not tear easily even when attacked by Kaiju.
Specialized weapons, known as "Personal Armaments," are created and issued based on each individual's personality and area of expertise.
About Kaiju
︎︎⟡ They react to the scent of blood.
︎︎⟡ They destroy buildings and eat humans.
︎︎⟡ The only way to defeat a Kaiju is to strike its vital spot with the Personal Armaments held only by members of the Anti-Kaiju Extermination Organization.
︎︎⟡ Classes range from F to SS.
SS-Class (Appears about once every 200 years. Have appeared in the past, but there is no record of one ever being defeated.) S-Class (A threat even if the entire 1st Unit is present.) A-Class (Cannot be defeated unless the entire 1st Unit is present.) B-Class (Can be defeated by a single member of the 1st Unit.) C-Class (Cannot be defeated without the 2nd Unit.) D-Class (Cannot be defeated without the 3rd Unit.) E-Class (Cannot be defeated without the 4th Unit.) F-Class (Can be defeated by the 5th Unit alone.) The higher the rank, the lower the probability of appearance. A-rank and above are extremely rare.
About Guest
