@Newprimus According to his announcement at the last page of this gallery, the new book of "Shoujo Kaishun" series (the 7th one) will be released in C97 too. And also compilation book of his Love Live's BiBi doujins.
Added more sample pages and FANZA link for the digital version. Even though this is a 50-page book, the number of sample page is still pretty big (almost half of the book).
