Editing Shissou Suru Shishunki no Parabellum:Volume1 Chapter2 (section)

===1===

The two boys and Shiho; they created their guns with their right arm and created a [Magazine] with their left hand at the same time. Though it seemed like a magic trick, there was no secret mechanism. They slammed their gigantic magazine in their left hand into their right arm gargantuan gun’s receiver. Without wasting a single moment they pulled the slide on top of the barrel assembly. The first bullet from the cartridge was loaded into the chamber as they pulled the slide. They could now fire at will.

As soon as her gun was fully deployed, Shiho’s power and movements enhanced. She lifted Itto with her left hand and kicked the bench at the two attackers before backing away.

“!”

The bench flew weightlessly and strongly at the two attackers. Let alone a girl, this act was impossible for any human. Upon deploying the firearm on her right arm (though the principle is still not understood), Hasegawa Shiho's strength was boosted. That weapon on her arm must have increased her strength.

The two men fired at the bench flying at high-speed toward them and turned it to a beehive. With a loud roar, the bench was demolished in a single moment. While debris blocked their vision, Shiho moved further away while shooting, an impact several times more intense than a roller coaster hitting Itto as they moved. Using high speed movements, Shiho jumped into the wooded area, hiding in the bushes.

Everything happened in an instant.
