Griffon Driver

The Griffon Driver (グリフォンドライバー) is armored vehicle developed by Academy City.

Principles
The Griffon Driver is a black luxury car, over two meters tall and over twenty-five meters long. The bulletproof vehicle has a body made of composite armor, bulletproof glass more than fifty centimeters thick, a door rivaling a bank vault with eight rods and a vacuum lock, and tires containing sponge rather than air, in case of hits from a sniper rifle or anti-tank mine.

Background
The Griffon Driver was originally developed for the use of the Academy City Board of Directors during World War III. After the war concluded, it came to be used by Kihara Yuiitsu to house her mobile biological laboratory.

Salome Arc
At some point prior to disguising herself as Keshouin Asuka, Yuiitsu visited her laboratory housed within the Griffon Drivers, parked in School District 17, in order to prepare the samples necessary for her plan to take revenge against Kamisato Kakeru and steal the World Rejecter, including a piece of Sample Shoggoth.
