.hack//4 Koma

.hack//4 Koma is a monthly set of 4 panel (a.k.a. Yonkoma) manga serialized in the monthly magazine .hack//G.U.: The World. Most of the 4 Koma are short gags, centering mostly around the main characters of the first (Kite, BlackRose, Helba, etc) and second (Haseo, Atoli, etc) series of .hack videogames. The humor is very tongue-in-cheek and often somewhat lewd, and has a number of inside jokes fans of the games can fully appreciate. There is also a continuing rivalry between the heroes of the 2 games, Kite and Haseo, much to the dismay of BlackRose and Atoli.

Additionally, in the release of the .hack//G.U Redemption game, four short '4coma' episodes were added to the game. The first three were featuring Haseo and Atoli while the last was of Pi and Yata.
