Dark clouds gathered over Mount Fuji and expanded at a terrifying speed. Before long, the sky within a 100-mile radius of that place was covered by thunderclouds, but they were still spreading.
150... 200... 300... 400... 800... 900...
The dark clouds stopped expanding at a radius of 999 miles and covered most of the sky in the Tokyo area. After that, hundreds of lightning bolts fell simultaneously, making Mt. Fuji tremble. The phenomenon alerted everyone in Tokyo, including the three official organizations.
They thought a space collapse with the highest threat level would appear in Tokyo. That made the higher-ups in the official organization worry. Thus, the Holy Union and the other two official organizations quickly dispatched their best Realizers to the epicenter of the phenomenon, Mount Fuji.
