Mars Games has announced that Isekai: Slow Life is teaming up with Demon Slayer: Kimetsu no Yaiba for a limited-time mobile collaboration.
The Isekai Demon Hunter Arc event runs from September 1 through September 30, 2026, on iOS and Android.
Demon Slayer Characters Join the Village
The collaboration brings six Demon Slayer characters to Isekai: Slow Life.
Players can access Tanjiro Kamado, Nezuko Kamado, Zenitsu Agatsuma, Inosuke Hashibira, Giyu Tomioka, and Shinobu Kocho during the event.
That lineup includes Demon Slayer Corps members, Hashira, and Nezuko, giving players a mix of Water Breathing, Thunder Breathing, Beast Breathing, and Insect Hashira representation.
Match-3 Battles and Event Rewards
In the Isekai Demon Hunter Arc, players select stages, encounter demons, and fight through a Match-3 combat system.
Rewards from battles can upgrade characters and help players clear harder stages, building toward a final boss fight. Players can also level characters to earn exclusive art, dynamic avatars, free and paid emojis, artifacts, and more.
Event Timing
On existing servers, the collaboration will be available for 21 days.
New servers launched during the event period will keep access through September 30, 2026. Mars Games gave September 22 as an example, meaning players joining through a later server will still have until the end of the month to play.
