God

The sky turned red. The city started eating itself. Akino Nana, a first-year university student, was nobody — until the world ended around her. Warriors are falling from the sky.Each one summoned from a different world.Each one carrying losses too heavy to name. A god called them here.But no one knows why. Behind the chaos lies a shadow organizationpulling the strings of the world's rulers.And behind them, something far worse. Eight strangers. Eight worlds.One war that was designed before any of them arrived. This is God's Invitation.And none of them remember accepting it.
