Case Cannon 「鞘型電磁砲, kēsu kyanon, lit. "Scabbard Type Electromagnetic Gun"」 is the scabbard of Gobta's Kodachi, which doubles as a gun.
Abilities
It has a coiled wire and magisteel lining the inside, and a replaceable projectile in the bottom. It uses Black Thunder, which was imbued into it by Rimuru, to force the projectile out like a rail gun.
Trivia
- At the time of Case Cannon's creation, Rimuru decreed that no other gun is allowed to be created, as he trusted only Gobta with such a powerful and revolutionary weapon. It wasn't until much later in the story that Rimuru changed his mind and allowed the creation of other guns.
