七つの大罪 ウラ話大放談〈全公開〉

A single, oversized issue from 2020 by Kōdansha, 七つの大罪 ウラ話大放談〈全公開〉 is a behind-the-scenes companion to the The Seven Deadly Sins manga. It collects creator interviews, discarded story concepts, and production secrets, offering dedicated readers an unvarnished look at the series' development. As a standalone volume, it's a candid, archival peek behind the curtain rather than a narrative installment.
