Inspired by the hit Ubisoft franchise Watch Dogs The Tokyo Metropolitan Government decided to introduce J-ctOS, an urban infrastructure management system developed by Blume Japan. People's lives have changed completely due to the convenience of improved infrastructure, and the ease of interconnectivity. Everything is fine, as long as they don't think too hard about what lurks in the shadows behind closed doors at the Blume corporation. "It's a great-looking manga with detailed backgrounds that bring the futuristic setting to life. It's like a fun action flick, albeit one you've probably seen before: scrappy underdogs taking on the world when it didn't seem like they had a chance." -- Lauren Ortini, Anime News Network.
