One of the world’s biggest manga is about to get the ultimate guidebook. The Berserk Official Guidebook is an indispensable owner’s manual to Kentaro Miura’s Berserk. The roadmap to the decades-old universe of Berserk, which includes never-before-seen artwork, will be available March 14. The 200-page paperback has an MSRP of $14.99.

Berserk has run for 25 years and 38 volumes, with Dark Horse moving 1.5 million English-language copies of the series. Dark Horse released the most recent volume in July (see “Dark Horse Goes 'Berserk'”), and the franchise is a top ten here in the U.S. (see “Top 10 Manga Franchises - Spring 2017”).
