Seven Seas Licenses Sleeping Dead Boys' Love Manga Omnibus

(January 14, 2026) — Seven Seas Entertainment is thrilled to announce the license acquisition of the Boys Love manga Sleeping Dead by NEMUI ASADA. Frankenstein's Monster meets Boys' Love! An unfortunate incident leaves one man caught between dead and alive—and stuck with the man who made him that way. The dark BL manga makes its way to English print in a single omnibus edition!

Sada is an earnest high school teacher admired by students and colleagues alike, a man who always goes above and beyond both inside and outside of the classroom. One night while walking through the city, he stumbles upon a student being violently attacked in an alley. As he tries to call for help, Sada finds himself on the end of the attacker's blade, bleeding to death on the ground. When he wakes up on a slab in an unknown laboratory, he comes face-to-face with his savior, a scientist named Mamiya. But Sada quickly realizes that in cheating death, he has become something...inhuman. What's more, he's now fully dependent on Mamiya to survive. What awaits him in this new life of death and deadly secrets?

Sleeping Dead (Omnibus) will be printed for the first time in the English language in December 2026 for $29.99 USA / $39.99 CAN, with the series available in a single omnibus edition. An ebook edition will also be available on digital platforms.
