Purifier

Purifier is Umika Takemi's primary weapon in End War Online, which can be swapped between its default submachine gun form to a rifle form for longer ranges.

Design
Purifier is based off the MP7 with the following modifications:
 * Redesigned, sleeker frame with a modular construction
 * A quad-rail system at the front to mount attachments as necessary
 * Modified internals designed to increase damage and accept a variety of 9x19mm Parabellum bullets, like anti-angel or anti-demon rounds
 * Side-mounted Laser sight
 * Trijicon RMR Type 2 Reflex Red Dot Sight with Adjustable LED
 * Vertical foregrip/flashlight module
 * Ergonomic, retextured handgrips
 * Attachable rifle barrel-shroud and additional rifle-based modifications

Trivia

 * Some of Umika's modifications inspired the modifications for Haru's Hailstone SMGs after Haru observed her primary weapon in action.
