Slugline: hack is just a very bad cough
.hack is one of those series that appears to be very popular despite all of my attempts to understand it. Considering that there is little attraction for me towards a humorous take on it. It seems that most of the volume requires previous knowledge of the .hack characters and story in order to get the jokes, though I suspect even if I did understand more of the references I would not find them very funny since the their setups are not very interesting. The volume is actually a compilation of four different creators take on .hack, though Koichi Sumimaru is responsible for most of the material. This is unfortunate, since that material is the least funny in the volume despite giving the title it's name. The 4koma, or four panel gag strips, starts the volume, making it a hard slog to wade through it and reach the other creators contributions. Most of the other creators' material can be understood on its own, without being already immersed in the .hack universe, but by the time you reach it any enjoyment that could be had has been leached away. Unless you are a hard-core .hack fan, especially of The World and The World R:2, there is nothing here worth your time.
.hack//4koma is also available from Right Stuf, Intl., an online retailer specializing in anime and manga.
