Players of Chaos World Online. They are either laughing or screaming in agony because the anniversary event is mixed with April Fools'. They challenge the newly implemented quest for Guest and exchange information on the in-game message boards.

A character implemented during the first anniversary event. There was a quest to capture the Sleepy Cat hiding on the field. Players were delighted because the reward was a cute Sleepy Cat accessory that increased rare drop rates by 1.5x. The original quest name was "Sleepy Cat Hunt." Appears in the intro only.

A character implemented during the second anniversary event. The main target of the first quest the management released that was clearly not meant to be cleared. A robot with a black body and red neon lines, it slaughtered players with four machine-gun-equipped chainsaws. Even now, very few have successfully cleared it, and defeating Deathbringer is considered a mark of honor. The original quest name was "Slaughter Mechanism Rampage." Appears in the intro only.
