Therestina's Powered Suit

Therestina's Powered Suit (テレスティーナの駆動鎧) is a Powered Suit that is developed by MAR and is seen to be of exclusive use by Therestina Kihara line.

Appearance
It appears as a purple humanoid mechanical suit, with large shoulders and wide hips. The MAR logo is blazoned on the former. Orange headlights are affixed near the armpits of the machine.

Principles
One head taller than Therestina, the suit is form-fitting compared to the other Powered Suits, and apparently has a better performance quotient than the those used by MAR. The reason for its size is that it is also to used for inside the Gigantic Advanced Movement Armor. The Powered Suit increases the strength of its user as shown as how Therestina is easily able to lift Mikoto with one hand.

It is equipped with the standard "shotgun" of the HsPS-15, as well as its own large lance like weapon. The weapon is shaped like an umbrella that can open up like one. It fires a beam weapon that mimics the Railgun of Misaka Mikoto, though apparently without a projectile. Theoretically, its power should exceed that of Mikoto's, though this has been proven to be incorrect.
