This is the prologue book for Key's new work "anemoi," distributed at the Visual Arts (Key) booth during Comic Market 107 in the winter of 2025. Key's booklets are usually B5 size, but this time it was a larger A4 size. It's a 24-page, all-color book. It was protected with a clear book cover immediately after acquisition. This booklet is highly recommended to have before the release of Anemoi. It will be shipped with measures to prevent water damage and bending. I plan to list other Key-related goods as well.
