The comics are in the style of traditional 4koma and feature non-canon encounters between characters from both universes. Initially, the humor is derived primarily from .hack//Games, but as the series progresses, it delves into exploring how Kite and his companions could be integrated into the storyline of .hack//G.U. The majority of the humor comes from Kites altered character traits or the over-the-top personalities of other characters, particularly Atoli.
.hack//4-koma was published in English by Tokyopop on May 30, 2010.
