I think Taiyo Matsumoto is my favorite manga writer/artist. So far the story is nothing really special– at its core, it's pretty predictable, but I enjoy Matsumoto's pacing and drifts into more abstract sequences. Before this, I had only read Tekkon Kinkreet, but now I see that he has a thing for duo characters that offset one another. It's clear that Smile and Peko are Black and White (the two protagonists from Tekkon Kinkreet, although less developed. It's a fun read so far. I'd give the story 3 stars, but the art pushes it to 4, as Matsumoto conveys so much with his wobbly lines and loose expressions/postures. He has beautiful depictions of the ping pong matches that I don't think many other artists could pull off. This series isn't of the caliber that some of his other works are, but it's still a great read.
