GGO (Gun Gale Online)

Kikuoka has recruited Kirito to investigate GGO, and so he logs in. To lure Death Gun into targeting him, he hopes to enter Bullet of Bullets (BoB), a tournament to decide the most powerful gunman in GGO. But as a first-timer, he doesn't know his way around this game, and soon loses his way, when he catches sight of Sinon and approaches her.
