This is a short story about Danbo. Danbo is perceived as a group of boxes that looks like a robot. Danbo originates from the manga (Japanese graphic novel) "Yotsuba&!" Its first appearance was in chapter 28. The name "Danbo" itself comes from the term 段ボール (or 'danBOORU') which translates as corrugated cardboard.

So, given he's a cardboard box robot with 'Amazon.co.jp' written all over it, I thought it'll be perfect to advertise Amazon. My bigger version of Danbo was needed for this little story. 

Sidenote: Amazon.co.jp is Amazon.com but for Japan.
