Akihabara isn't just the setting here, it's a character that actually loves you back, a place that exists specifically for people who don't fit anywhere else. The show gets that comfort in obsession, that real thing where your weirdest interest becomes your whole identity and that's genuinely okay. The combat itself is ridiculous (stripping demons naked is the solution), but that's not the joke, the joke is that in Akiba, ridiculous is the only language that makes sense.

Otaku siblings Tamotsu and Niwaka Denkigai are out shopping in Akihabara when the district is swarmed by the Bugged Ones, vampire-like monsters dressed in cosplay who take control of anyone they bite. When one of them corners Tamotsu, he is saved by Matome Mayonaka, a mysterious girl who fights with a baseball bat. After he is mortally hurt shielding her, Matome brings him back as a powerful Bugged One like herself. Together with the energetic cosplayer Arisa Ahokainen, they form The Electric Mayonnaise and defend Akiba by tearing the clothes off the Bugged Ones and leaving them exposed to sunlight. The result is a supernatural action comedy with plenty of ecchi fanservice, set in a neighborhood that welcomes every kind of fan.
