Phantom Bullet Arc
Kirito bought «Kagemitsu G4» because it is the only weapon he found that resembles a sword, since he was used to clashing with swords in Sword Art Online and ALfheim Online. Kirito is quite proficient with this saber, as he is able to slice up bullets flying at him. Despite being a lightsaber, it is unable to cut through all materials, as shown when pitted against the Starship Metal Estoc.
