-Story-
WHEN HUMANKIND ADVANCED INTO SPACE, THEY ENCOUNTERED AN ARMY OF WEAPONS SIMILAR TO THOSE OF EARTH'S CREATURES.
PUSHED BY ENEMY WITH STRONG DEFENSIVE WALLS, HUMANKIND WAS FORCED TO RETREAT.

HUMANKIND NAMED THEM "IMITATORS" AND CONDUCTED RECONNAISSANCE IN VARIOUS DIRECTIONS.
AS A RESULT OF THE RECONNAISSANCE, IT WAS FOUND THAT THEY EXISTED EVERYWHERE.
HOWEVER, THE PURPOSE OF THE "IMITATORS" WAS UNKNOWN, AND THERE WAS NO TELLING WHEN THEIR INVASION OF THE EARTH WOULD BEGIN.

AFTER MUCH RESEARCH, HUMANKIND DISCOVERED THAT THE USE OF FRAGMENTS OF ENEMY WAS EFFECTIVE.
THE PIECES OF ENEMY WERE NAMED "KIRIMI" AND A SPECIAL BULLET CALLED "SUSHI" WAS DEVELOPED THAT USED "KIRIMI".

TO PREPARE FOR A FULL-SCALE INVASION BY THE "IMITATORS" HUMANKIND BEGAN RECRUITING MERCENARIES AND COLLECTING "KIRIMI".
THE CHARACTERISTICS OF "SUSHI" VARY GREATLY DEPENDING ON THE "KIRIMI" USED, AND MERCENARIES ARE REQUIRED TO USE DIFFERENT "SUSHI" DEPENDING ON THE SITUATION.
