The SSIIVA System (Squad Support Independently Intercept Volleying Arms) is a personal battle system used by Kei and Yuri in the Dirty Pair Movie. Unlike a lot of high tech armor we see in anime, the SIIVA System does not enhance the user’s speed or strength. It is a harness for mounting a variety of weapons along with a sophisticated array of sensors and computer systems to aid in using those weapons properly. Kei and Yuri’s suits have different weapons but both suits have sensors located on the shoulders and micro missile pods mounted on the hips. The suits are powered by small nuclear batteries - one can be seen protruding from the back of Kei’s suit.
