The Flash of The Gremory Clan

by NerdsAlterEgo

Rias had another forbidden piece besides Gasper, but she never used him due to fear of her brother Sizreach. She considered having him under an alias and a powerful illusion to make up for the lack of contact they had in the Brittanian military but by that time she had gotten Issei. However he is needed more and more as Issei is too nice to do what is necessary. Take a ride?

1. Chapter 1

"Standing by,"

Rias frowned as she heard the familiar mechanical voice of her forbidden piece's Sacred Gear, she would never get used to it as long as she lived. before she could say anything something blurred between her and Viser and started appearing and reappearing at various points a good distance from the stray. Its arms fell off before it even realized what was happening, Szreach had mentioned something about being able to move from a pawn to a King using the experimental piece she had used in this one's resurrection. Something spun and Rias realized the piece was beside her twirling around what she realized was a modified machine pistol, his chest armour now perched on the sides of his shoulders.

"Burst Mode,"

Before she could question him on what had happened or how he had arrived so fast he vanished again, so quick she barely noticed it. The roar of gunfire echoed across the desolate house and the suddenly headless body of the stray smashed into the ground, before the sound of his weapon had even ended. "3..2..1. Time out. Deformation," He was in front of her again, a bloody sword with a blade glowing crimson and the gun in his hand.

Issei chose that time to interrupt. "Just who was that guy Prez? He seems to be a perfect fusion of the pieces you described a while ago. Did you get him from some sort of lab or something?" Kiba gritted his teeth at this comment while the guy just turned around, revealing that his armour had vanished.

His eyes were blood red with three comma marks swirling around them. The clothes he was wearing were the standard Kuoh Academy uniform but on a military bent, with a black-scarlet trimmed leather jacket to accent it. The sword and guns were replaced by an over-sized katana that he handled just as well as a regular one.

"Anything else Corporal Lilith..no Rias..oh s..t Asuka?"

Rias looked at her smartphone and realized that a Grimm attack had occurred in the rural town of Noihara, near Kuoh. The message was immediately received and the mysterious piece vanished again, hopefully until she needed him again. The sounds of inhuman wails and shrieks, as well as the unwanted sound of police sirens closing in on the house, were enough to keep the busty redhead and her servants distracted as they quickly departed from the empty residence.

Issei however was mentally ecstatic as he was finally able to find something that would allow him to use his brain without having to fake perversion. "Just who are you Mr. Trump Card?" he said softly, although Koneko heard him clearly. "And what is your connection to Asuka-buchou? I promise I will find out..if only to relive the stress of pretense perversion,"
