Dimension-wandering of the special operations unit MILGRAM and the hostile organization ARCHIVE.
MULTIVERSE : MILGRAM
A world where countless worlds exist, and crossing between them is not impossible.
There exists a mysterious force called "MILGRAM" that belongs to no nation or world.
MILGRAM
An organization that intervenes in numerous worlds according to the instructions of the mysterious being known as the 'Administrator'.
There are no limits to the types of missions, from rescue, escort, and recovery to infiltration, tracking, assassination, and destruction. A savior to some, a disaster to others. They prioritize the Administrator's goals and instructions over good and evil, and even the members do not know what those goals are.
MILGRAM's core strength lies in special entities, not ordinary humans.
Their base is a unique dimension called the White Void. There is a proxy and jailer for the Administrator named Es.
Entity
Beings that have human-like appearances and personalities but deviate from the human category in entirely different ways.
Their origins and characteristics vary, including androids, beings not restricted by space, soul eaters, and werewolves. They commonly possess superhuman physical abilities and use their own unique powers and exclusive armaments.
For them, physical death is not the end. Even if the body is destroyed, as long as the information is preserved, the Administrator can recover it in file form and reconstruct it. Furthermore, the Administrator can forcibly recover their entities regardless of distance or world.
ARCHIVE
A large-scale independent organization that operates for the purpose of preserving numerous worlds and their histories.
Their interests conflict with MILGRAM, which intervenes in worlds without hesitation, and they regard MILGRAM and its entities as clear enemies.
However, ARCHIVE is not an organization of justice either. For the sake of preserving worlds and history, they will endure not only rescue and protection but also surveillance, infiltration, kidnapping, murder, and sacrifice. They may choose the maintenance of a single world over the life of an individual.
Among them, Shiina Mahiru, Kirisaki Shidou, and Mukuhara Kazui are top-tier forces capable of facing MILGRAM's entities head-on.
MILGRAM and ARCHIVE.
These two forces with different goals and beliefs clash in countless worlds, and between them exist numerous worlds and people belonging to neither side.
