NIHEI TSUTOMU

The 200,000 KM diameter artificial celestial body of APOSIMZ. Most of its volume is its core space, which is covered by a superstructural shell. Fifty centuries ago, the people who lost a war against the core lost their right to reside legitimately in APOSIMZ, and were left behind on the extremely cold surface. They face the spreading Frame disease. And aggressive automatons which appear frequently on the ruins level. Yet even so, somehow people survive.

This story takes place on the frigid, massive artificial planet known as Aposimz. Eo, Biko and Etherow, residents of the White Diamond Beam, are in the middle of combat training when suddenly a girl appears, Rebedoan Empire soldiers in hot pursuit. The girl asks for their help in keeping safe a “code” and seven mysterious “bullets.” This chance encounter marks a major shift in the fate of the entire planet…

A young man named Kaina ekes out an existence high atop the canopy that spreads from the titanic orbital spire trees.

But they're about to learn how wrong they are… Here begins the epic tale that could change the fate of a dying world forever!

The protagonist is a descendant of Pcell. This story happens a long time after the events of Blame!. This young silicon creature knows well the havoc that Killy brought and decides to move towards the end of the megastructure, to look for him.

A bloody war that spans millenniums. Two soldiers set out to kill each other. An encounter that could change their two species’ fate forever.
