A pretty weak volume as far as things goes, this outing of Outbreak Company finally sees the author bring out the "Akiba visit" trope after 8 volumes of building up the otaku culture. The gist of the volume revolves around Shinichi getting some bad news about his family and rushes back home, so the rest of the cast join him along for the visit and make a side-trip to the holy land of otakudom, Akihabara. Unfortunately, they bite off more than they can chew and suddenly they are forced in to a major international crisis.
While this sounds like a pretty promising setup, it's kinda ruined by the hackneyed way it's set up to happen. A lot of plot holes and disregard of previous plot devices went in to this visit to Earth, so the major conflict of the volume feels like "well he had that coming!".
The majority of cliches about international espionage rings and politics suddenly get introduced as well, leaving a rather jarring feeling to things happening and most of it also felt rather contrived and preying on standard stereotypes, leading to a lack of excitement for me in terms of enjoying the plot.
This arc also gets spread over two volumes as well, ending on a pretty straightforward cliffhanger contributing to my lack of satisfaction. It really does feel like the author seems to be slowly running out of ideas to extend his original vision of the series, starting to indulge in rather standard trope plotlines which unfortunately aren't executed very well. I feel it's a sad waste of the setting.
