"Who are they blaming?"
"Nobody."
Several days after the incident in rural Nihon, news of the multiple holes opening up have scattered throughout the entire world like wildfire — they could not really hide it even if they wished to, and why would they?
Rhys and the others were able to successfully flee the country with no problems at all and travel to Russea. It couldn't even be called difficult as the entire country was in a state of panic, and not to mention calamity — literally.
Nihon declared a state of calamity and have evacuated all of their population as far away as possible from the Holes; right now, more than half of the people in the country are on the edge of the island.
Conscription was also extended to all Explorers, no exemptions — be they women or people of a certain age.
