File No. 062 Phaser フェイザー銃

A stun gun manufactured in 2100. Its power can be adjusted up to ten levels. Level one only inflicts sharp pain, but level can kill an elephant in one shot.

It uses a bio-authencation system that prevents anyone other than its registered user from being able to fire it.

The gun that Ei Sekigahara uses was given to him by the Tomi Kisaragi android, along with some medicine, when they escaped the underground Shikishima Tech Lab in 2104 after the Sentinel Infection Incident.
