Mugino beams

The wall was thick.

It was supposed to be composite armor created from an alternating sandwich of polycarbonate and aramid fiber.

That meant it was far stronger than a bank vault.

But it was burned through in an instant.

A light blew away the unofficial research facility’s exterior wall along with the security guards who had noticed something was wrong.

A few people easily entered the secret area through the 2m hole that was still glowing red.

Then three beams flashed out in an almost offhand way.

That was all it took to blast through the labyrinthine research facility’s walls, trigger explosions, and tear the place to pieces. The security that should have activated in an emergency – not just the thick barricades, but the sprinklers and the alarm as well – had their wiring severed and failed to function.

After five seconds of this, everyone still alive had to have noticed something.

These blasts were not at all offhand. The beams of light were accurately melting and sealing every last exit, trapping the scattering researchers and security guards in their own personal jail.

Some girls walked through it all as casually as if this were the hallway at school.

The curvy girl in a summery sleeveless cardigan and a yoked skirt was Mugino Shizuri.

The girl with shoulder-length black hair in a pink track jacket and shorts was Takitsubo Rikou.

“Damn, I really need to stop eating so much bread. My legs are bloated.”

“Mugino, your problem is that you don’t exercise, not what you eat.”

It was a hot night, but the air conditioning must have been a little too cold because expressionless Takitsubo rubbed her bare thighs together as she replied.

“Hey, I’m out in front killing most of them myself.”

“You can kill anyone instantly with your power, so I don’t think that counts as exercise.”

Mugino Shizuri gently massaged her stocking-covered thigh with a hand.

Even during their carefree conversation, beams were flashing out from Mugino’s other palm. She vaporized an entire group of security guards who were unable to escape with the reinforced emergency exit door blocked.
