I was introduced to and bought this manga at the Yuricon booth at Anime Boston, and had it described to me as "A manga where a lesbian actually is happy to be a lesbian", and I must say that's a pretty good summary. Being semi-autobiographical on the part of the author, she says that she wrote it specifically to not be a depressing, forbidden love story, and it manages to deliver on that promise while not being too over the top in its message.
The art is simple but manages to convey adult concepts at the same time and is consistent throughout the story. There are
a few scenes showing sexual stuff, but none of it comes off as pornographic. Rica and Miho talk about this a few times, but it's usually matter of fact and the story doesn't dwell on it for too long. The two have a very sweet relationship that develops realistically and plays out like a real love story, while still managing to make you laugh out loud a few times.
There's also a colorful cast of characters besides the two female leads, and the explanations of lesbian culture are both informative and easy to understand. For those who are tired of the usual schoolgirl angsting this series is a breath of fresh air, and hopefully just one of many of this type to get to the States thanks to Erica Friedman and her people at ALC Publishing. Purchasers of the ALC manga will also be treated to a few extras after the story, but I'll keep those secret for now.
