What's not to like? A transexual looking reincarnation of a legendary Go player teaching a kid how to play Go and paved out a career for him.
Good art, good story, and the ending was just absolutely nice! Also I love how they teach you a little bit of Go at the end of every episode. The anime almost made me wanted to start playing Go, ALMOST.
The only turn offs were the Go salons, I mean wtf? I sure as hell haven't seen a street full of Go salons like what they showed in the anime. Only thing I saw in real life that's even close to that is a casino.
P.S. Keep in mind as you watch the anime that switching hands DOES NOT make you play better, the artist should get shot for that; setting that aside, the anime is great.
