Since 2019, few anime series have made a global impact like Demon Slayer – Kimetsu no Yaiba. With stunning animation and a heartfelt story about siblings Tanjiro and Nezuko, it became a phenomenon. However, as the series approaches its conclusion, fans have no reason to be sad because another promising series is on the horizon, hailed as the rightful successor to Kimetsu no Yaiba.
Specifically, Fullmetal Alchemist creator Hiromu Arakawa is teaming up once again with studio Bones to adapt her new manga, Daemons of the Shadow Realm, into an anime. This series will stream exclusively on Crunchyroll.
Fullmetal Alchemist Creator Returns with a New Anime

Hiromu Arakawa is a major name in manga, best known for the masterpiece Fullmetal Alchemist (2001-2010), which Bones adapted into two highly successful anime series. She later created Silver Spoon and now Daemons of the Shadow Realm, a manga currently spanning 10 volumes.
Daemons of the Shadow Realm follows twins Yuru and Asa, whose names mean “day” and “night.” Forced to live apart because their birth is seen as an ill omen, Yuru discovers the Daemons, paired souls bound to humans, and sets out to find Asa while learning to control these Daemons to change their fate.
The series was announced at Anime Expo 2025. Although no official release date has been set, the collaboration between these industry giants has already sparked excitement in the community.
Daemons of the Shadow Realm Poised to Fill the Void Left by Demon Slayer

The similarities between Daemons of the Shadow Realm and Demon Slayer are striking. Both focus on sibling bonds and battles against demonic forces. The challenging journey of twins Yuru and Asa, along with a prophecy about an apocalyptic event, promises drama and emotional depth.
As Demon Slayer concludes, it will leave a significant gap for fans. However, the timely arrival of Daemons of the Shadow Realm could fill that space. With an engaging premise and the backing of legendary names like Hiromu Arakawa and studio Bones, this anime has strong potential to become the next major shonen hit.
