Black Spiral-Type Positron Rifle

Weapons used by Black Spiral and the Daughters of Eve, these positron rifles - often just referred to as BSPRs - were initially designed at the Scorpio Secret Research Base but were never really mass-produced for use by the Star Army of Yamatai due to the inherent hazards in using a particle projection weapons in any atmospheric environment (often spelling destruction of the weapon and damage to the pilot). Ketsurui Fleet Yards turned to the use of the new KFY-M2-W2901 aetheric saber-rifle instead.

However, most of the Mishhuvurthyar-inspired positron rifles remained in the hands of Black Spiral: several hundreds of test models. The weapons proved to be a considerable asset to most of the rogue operations they participated in, boasting enough power to easily shear through durandium plating and being capable of breaching even the powerful forearm shielding of the Ke-M2-2D "Mindy II" Power Armor or larger vessels as long as it kept being used for space battles only. The two organizations still using it switch from it to the Type 29 saber-rifle depending on the situation, with the BSPR being favored for taking down most better shielded targets.

Externally, the weapon looks like a reinforced, black-colored Ke-M2-W2705 Accelerated Plasma Rifle labeled Ke-M2-W2809. It actually looks sturdy enough to be used as a club.
