Where may I start? Ubunchu is a manga who was made to get the anime and manga fandom closer to the operating system Ubuntu (Linux). Therefore, the plot turns around topics like Linux, licenses and community.
This may sound boring, but in fact it's not. The comical perspective makes it easier to explain, for example, about licenses.
Visually is a bit dry, the characters' design is what we may expect in these type of stories developing in a school. What makes it special is that it's an Indie non-profit work.
The plot revolves around a club of ITs, therefore is expected to deal with things
related to computers. Some of the gags may be understood only by people working with Linux.
There's something missing with the characters, they need more weight on the plot, to be more intimate and not just OS users.
Ubunchu is a manga for the community, it gets better chapter by chapter. We must remember that it's an indie work. It is enjoyable but needs some more adjustments.
