Hiromu Arakawa, the acclaimed creator of Fullmetal Alchemist and Silver Spoon, is officially returning to the anime spotlight. Her most recent manga, Daemons of the Shadow Realm (Japanese: Yomi no Tsugai), has been confirmed for an anime adaptation, set to premiere in 2026. The announcement was made at Anime Expo 2025 by Crunchyroll, which will also exclusively stream the series worldwide.
Given its themes, characters, and supernatural setting, Daemons of the Shadow Realm is already being hailed as a potential successor to Demon Slayer: Kimetsu no Yaiba.
From Manga to Anime Adaptation
Originally serialized in Monthly Shōnen Gangan in December 2021, Daemons of the Shadow Realm has been collected into 10 volumes as of mid-2025. The story follows twin siblings Yuru and Asa, who inherit the mysterious ability to control powerful supernatural beings known as Daemons. Torn apart at a young age, the siblings must navigate dangerous forces while struggling to reunite.

At Anime Expo 2025, Crunchyroll confirmed the anime adaptation with major details:
- Studio: Bones (known for Fullmetal Alchemist: Brotherhood, My Hero Academia)
- Director: Masahiro Ando
- Series Composition: Noboru Takagi
- Character Designer: Nobuhiro Arai
- Music: Kenichiro Suehiro
- Main Cast: Kenshō Ono (Yuru), Yume Miyamoto (Asa), Yuichi Nakamura (Dera), Misaki Kuno (Gabu-chan)
The anime is slated for release in 2026, though a specific date has not yet been announced.
Parallels with Fullmetal Alchemist
Arakawa’s fans will immediately recognize her signature storytelling style. Much like Fullmetal Alchemist, Daemons of the Shadow Realm revolves around the bond between siblings, who must face trials that test their trust, loyalty, and resilience.

However, there is a key difference: while Edward and Alphonse Elric from Fullmetal Alchemist relied entirely on one another, Yuru and Asa’s relationship is defined by separation, mistrust, and vastly different experiences. Yuru grows up in the safety of his village, while Asa develops an awareness of the outside world. Arakawa flips the sibling dynamic, presenting a new tension at the heart of the narrative.
Comparisons to Demon Slayer
Beyond its ties to Fullmetal Alchemist, Daemons of the Shadow Realm is drawing frequent comparisons to Demon Slayer.

- Sibling Bond: Both series place sibling relationships at the center, tested by supernatural evil.
- Dark Fantasy Setting: Demons, curses, and dangerous powers echo the thematic struggles in Kimetsu no Yaiba.
- Emotional Storytelling: Like Demon Slayer, Arakawa weaves personal sacrifice, moral conflict, and the battle between light and darkness into her narrative.
With Demon Slayer now entering its climactic conclusion, Daemons of the Shadow Realm is positioned to fill the void for fans craving another epic shōnen fantasy rooted in sibling bonds and high-stakes battles.
Why Fans Are Excited
The anticipation for Daemons of the Shadow Realm is amplified by several factors:
- Hiromu Arakawa’s Legacy: Having created one of the most beloved shōnen manga of all time, expectations for her new work are naturally high.
- Studio Bones: Known for its high-quality animation and faithful adaptations, Bones provides confidence in visual excellence.
- A Modern Take: While recalling themes of Fullmetal Alchemist, the story feels modern and darker, aligning well with current audience trends shaped by Demon Slayer and Jujutsu Kaisen.

With its compelling sibling dynamic, supernatural elements, and the creative genius of Hiromu Arakawa, Daemons of the Shadow Realm has all the ingredients to become the next major anime phenomenon. Though it is too early to call it the definitive successor to Demon Slayer, the potential is undeniable.
As the anime industry looks to its next flagship shōnen title, Daemons of the Shadow Realm may very well step into that role when it premieres in 2026.
