Exstetra

Suddenly fused with a different world, Tokyo has been transformed. This world called Amazia is a world determined for ruin. Caught up in this vast change, the main character descends onto Ameijia. Ameijia's dwellers say he is Prisma, the only one who can save the world from destruction. Will you be able to stop the two worlds from fusing, return the world to its original state, and save all the people who have assimilated into “nothingness” from the great change?
