The clouds floating in the night sky promptly scattered and from far away were lightning. An enormous pillar of light descended from the heavens. However, the pillar was red. Like thousands of flaming arrows moving in close proximity, the pillar was spear striking one of the four Misawa Cram buildings.

The red lotus pierced roof to basement, crushing the tower to half of its original height like a squashed aluminum can. The glass shattered and interior decorations flew about in chaos.

However, there was more. The tower that was hit directly dragged the two neighboring towers by the overhead corridors, leaving the last unaffected tower like a tombstone.

The act of madness left Kamijou in bewilderment.

The buildings were twisted, cracks formed along the walls and people fell through the gaps like dust being patted from pants. Numerous pieces of falling debris utterly devastated the surroundings like a meteor shower. The only possible upside was the lack of people that the Opila rune had caused.

Dust was just part of it. The previously falling rubble began to float in midair and the crumbling walls flipped erect. The debris moved together like the pieces of a jigsaw puzzle and completely reformed the smooth towers that looked freshly renovated.

It was like watching a show in rewind. The collapsed towers were upright and the falling people were reabsorbed through the cracks. Most of the damage was repaired and soon, all four Misawa Cram towers were reformed as if nothing had happened. Even the neighboring buildings crushed by rubble reverted to what they were prior. One would have wonder if Kamijou’s memories were being manipulated.

With one sentence—just a single sentence—like “Revert back to normal” the entire building stood back up like a living creature
