Here's a link to volume 1 on Amazon: http://www.amazon.co.jp/%E3%82%A2%E3%82%AB%E3%83%A1%E3%81%8C%E6%96%AC%E3%82%8B%EF%BC%81-1-%E3%82%AC%E3%83%B3%E3%82%AC%E3%83%B3%E3%82%B3%E3%83%9F%E3%83%83%E3%82%AF%E3%82%B9%EF%BC%AA%EF%BC%AF%EF%BC%AB%EF%BC%A5%EF%BC%B2-%E3%82%BF%E3%82%AB%E3%83%92%E3%83%AD/dp/4757529805

It's all in Japanese though.
