It's a weird short story that probably would have benefited from having a few more chapters. I'd recommend reading it, since it's a short and interesting read in a way that's not what you'd expect. The summarize, two young kids (Reiko and Hiroshi) discover a starving Pokemon-like creature one day and kindly feed it. They discover the Pokemon-like creature is actually a space alien saleswoman (Ponko), looking to make big bucks by selling on Earth! When she finds out they're broke, she tries to leave, but is dragged back by.... starvation. Anyway, they work out a deal, where she'll sell them a copier that cancopy anything at all, but there's a catch. A very unfortunate and terrible catch that reminds you never to make a deal unless you know and understand all the terms and conditions attached...

Like I said, the manga's a bit too short, it needs a bit more meat to it, but that's due to some gaps in depicting character development, as there's a bit of a time skip to the second chapter, and a need for a bit more content revolving around the subsequent deals Reiko decides to make. However, the ending is quite interesting, as it creates and depicts new circumstances and might even be worth exploring in another short manga.
