Day 341 - 12:26 PM - Kachidoki Docks, Kachidoki, Reclaimed City, Ruins of Tokyo
Mark was pretty bothered about the unusual state of the Demons. Not to mention that sixteen-eyed silhouette he had seen after closely assessing the emotional state of the invading enemies.
There was something in the background that was beyond the knowledge of Mark. Even the Priestess and the Empress might not know about this either. If they did, or at least suspected to, they would have shared it in order to add it to their plans and schemes for this scenario.
But, no. The two leaders of the most powerful groups in current Japan clearly had no idea.
If Mark did not notice something was wrong, they would have been left out in the dark until it was too late.
