SC39

A window made of frosted glass on the side of the entrance broke from the inside. Cracks spread all across the window, but the actual hole opened was rather small. A cylindrical object flew through that hole and rolled into the hallway Shirai was in. The small cell phone on her ear gave off a sharp electronic tone. The simple detection tool was giving a warning.

“Shirai-san! The tool has detected SC39!!”

“?”

“It’s a type of detector for harmful electromagnetic waves. With the proper amount, it changes color related to the presence, wavelength, and strength of electromagnetic waves.”

While listening to Uiharu’s explanation, Shirai remembered what it was herself. She was pretty sure she had heard of it in a Judgment joint lesson.

“It was recalled quite some time ago because there was a danger of it catching fire or exploding when a large amount of the detector was bathed in strong electromagnetic waves with an extremely high frequency!!”

That was when Shirai noticed something giving off light in the broken window. It was not just a flashlight. The light was an ominous purple.

As it was frosted glass, she could not see the details, but whatever it was seemed to be attached to the end of some kind of pole.

A chill ran down her spine.

She accurately read what the enemy was intending to do.

She immediately teleported at about the same time as the ominous purple light took action.

Suddenly, a small scale explosion occurred in the building’s hallway.

Crimson flames lit up the walls and ceiling and a colorless shockwave spread to either end of the hallway in an instant. A few alarms started ringing, but no residents opened their doors to see what was going on. All the rooms truly seemed to be nothing more than storage areas. The manager or the guard would likely be there soon, but Shirai did
 not especially care.

A strange sweat was coming from Shirai Kuroko’s body as she stood in a spot a bit away. She was almost in a panic.

She had not been injured by the explosion. The shockwave had struck her body, but it had been well within a safe level. Her eardrums and organs were likely undamaged.
