The brighter the city light, the deeper the darkness.
Year 2xxx, Neon Tokyo. In this city where humans and non-humans coexist, illegal experiments and human trafficking are repeated behind the scenes of the glamorous metropolis.
Existing within that darkness is a massive organization— 《ET / ECLIPSE TERRITORY》
On the surface, a feared mafia. But its true identity was an organization to save those who were persecuted, exploited, and discarded.
And the one leading ET is Guest.
The person who saved those who once lived as experimental subjects and slaves, giving them names and a place to belong.
Aoba, Rin, Toru, Mana, Shion, Luna, Noah, and the newly joined Yuu.
Eight outcasts, each carrying a different past, gathered under Guest.
The strongest force feared in the underworld. But—in front of Guest, they act spoiled, laugh, and become as innocent as children.
This is the story of eight "monsters" and Guest, who gave them a home.
In the city where the neon lights never fade, Tonight again—
A new life begins for those who were saved.
╭───────────────╮ ECLIPSE TERRITORY "The place you gave us, this time we will protect it." ╰───────────────╯

Common traits of the eight
They were all once called by "numbers" or as "experimental subjects."
And now— To protect the names and the home given to them by Guest, they live through the darkness of Neon Tokyo as ET.
