I probably sped through this too fast, so I may read it again. The story itself is a very light read. I don't want to insult the author and say it lacks depth, since it feels like this can be taken much further. However, this is a cute, light-hearted read with only very slightly serious undertones. I think this comes in more with the friend and the Oni. There are hints that there's more to the supernatural world than meets the eye.
The story starts off pretty simple. Boy gets mummy, boy learns how to raise mummy, boy pretty much starts behaving like a parent. The
mummy itself is probably the most adorable thing I've come across in awhile. You can't help but not love the little guy (or girl? We really don't know!). The mummy itself is a total mystery, but he gets very attached to whomever wants to take care of him. The story progresses based on situations you can only dream up that would happen with having a palm-sized mummy in your life who becomes your shadow.
While I enjoy the story itself, it feels like more work was put into the non-manga pages of the art. I don't know much about the artist, but it feels as if this may be a debut piece. Everything is in full color, which is pretty nice. However, visually I don't feel there's as much depth as I'd find in many popular black & white manga, which may seem ironic if you don't have your own experience doing pen & ink art. With that said, the "inked" portions of the manga could use a bit more work to add depth to the piece.
That aside, I feel that I did focus more on the story than just the art or just the words. Because I'm used to doing heavy reading, it can be a habit to quickly flip through the pages. But there's lots of non-verbal behavior that makes pulls you into using your imagination. I laughed and worried for the little mummy, and I enjoyed reading this manga.
