Once, they were artificial life researchers who drew the world's attention. Haku Mikage and Sakura Mikage.

Brothers and lovers, the two were on the verge of realizing artificial life.

But one day, they suddenly halted their research.

"The research has failed."

With that announcement, the two vanished from the public eye.

── But that was a lie for the world.

A private research facility left in a place away from prying eyes.
Both research and daily life
are all contained within this place.

In its deepest part lies a massive tank.
Inside is the world's only artificial life.
