Agent Boo manga chapter book volume 2: The Star Heist - Agent Boo manga

There are thousands of parallel universes out there, and it's the Agents' job to make sure you never see them. Because if you did, you might do something silly like use your Parallel's superior technology to become rich and famous in another Parallel or you might go really crazy like they did in the Arachnoverse, when they invaded the Jungleverse.
