At Comic-Con International San Diego 2025, Kodansha Comics announced upcoming premium hardcovers for Witch Hat Atelier and Attack on Titan.  Also announced was Blue Lock Omnibus. All three books are due out in Spring 2026.

The Witch Hat Atelier: Grimoire Edition by Kamome Shirahama will reprint Witch Hat Atelier volumes 1-3 in a gold-foiled hardcover with nearly 600 pages.  The book will be a larger size than the manga, with premium paper, color pages, and bonus content.

Witch Hat Atelier is about a girl who dreams of being a witch but wasn't born one.  The first volume of the manga was in the Top 20 of full-year sales in 2024 (see "Top 20 Manga 2024").  An anime adaptation is coming on Crunchyroll (see "Trailer for 'Witch Hat Atelier'").

The Attack on Titan Definitive Hardcover Collection by Hajime Isayama will also collect three volumes in a hardcover with a faux leather cover, gold foil, library-style binding, and color pages.

The Titans are massive monsters that drove humanity to live in walled cities.  The manga series ran a total of 34 volumes, concluding in 2021 (see "'Attack on Titan' Manga to End").

The Blue Lock Omnibus reprints three volumes under an embossed cover.  The series, with story by Muneyuki Kaneshiro and art by Yusuke Nomura, is a sports competition manga where players complete in unusual challenges.  

The manga is releasing monthly to catch up with the over 30 volumes out in Japan (see "'Blue Lock' to Go Monthly") and has two anime seasons out.
