The answer to the lingering doubt lies in plain facts and a bit of luck. If the anime keeps performing well, it will head to adapt all 19 volumes of Undead Unluck manga, divided into 18 story arcs. The original manga behind the captivating supernatural story of Fuuko has been in publishing since 2020, but there isn’t a full stop to it yet. A new volume of the manga is set to debut in Feb. 2024.

The 190-chapter manga is broadly divided into two sagas: the 100th Loop Saga and the 101st Loop Saga. These sagas then further feature various story arcs, currently totaling 18. Here is every Undead Unluck arc in order as of the latest manga release.

100th Loop Saga
