Tsubomi Web Comic 「つぼみのwebコミック」 page opened up to the public a few hours ago. It’s updated every month on the 2nd and 4th Wednesday. Illustration was done by Kurogane Ken.
Aside from the availability of these four selections, there are also cute messages from Kurogane Ken and Mizutani Fuka for their new, currently on-sale books, Hoshikawa Ginza District 4 Vol. 2 「星川銀座四丁目 ２」 and Lonely Wolf, Lonely Sheep 「ロンリーウルフ・ロンリーシープ」, respectively. These messages are web only ;), so…check it out (even if you can’t read Japanese)!
Check the books out too if you haven’t already. They’re nice yuri stories.
UPDATE: According to Kurogane Ken’s retweet of a tweet, it works for Android devices too. I can also confirm that it works on my Samsung Galaxy S2. The web page itself looks pretty good on my screen. Reader also looks and works good. The page turning for the reader is a diagonal motion from left to right.
