Our notes on Kimetsu no Yaiba (Demon-Slayer)

What sets it apart

This is a Demon Slayer themed pack, centered on a Demon Slayer content mod. The project page says it adds demon slayers and the demons that hunt them, new dimensions, weapons, clothing, armor and food. It also mentions structures from the series and new combat and battle animations, including demon arts.

The latest mod list has 47 entries in all, so about 46 sit around that mod. Tinkers’ Construct, Alex’s Mobs, Aquaculture 2, Waystones, Traveler’s Backpack and YDM’s Weapon Master add general content. A Demon Slayer GUI pack and FancyMenu handle the interface. Performance mods include Embeddium, ModernFix, FerriteCore, Entity Culling and Oculus for shaders.

Both this pack and Isle of Berk (Claws of Berk) are published under the same Modrinth account (Kesselot). They share one Discord invite and one Ko-fi link.

Who it suits

Fans of the anime who want a combat adventure with some general content mixed in. Adventure, combat and kitchen-sink are its tags.

Before you install

Builds exist for Forge on 1.20.1 and 1.16.5. The latest version, 2.1.5, was published on November 6, 2026, on 1.20.1.

The page says the pack is based on the Demon Slayer anime and manga. Neither listing states any affiliation with or license from the rights holders, so nothing here should be read as official.

Playing with friends

Modrinth lists the pack as required on both client and server. The Modrinth page has no server setup steps and lists no server pack. The CurseForge listing does show server pack files, for 1.20.1 (2.1.5) and for 1.16.5 (1.0.7). The mod list includes “My Server Is Compatible” and ServerCore, which hint at server use.

The page carries a hosting promotion link and a Discord server. Questions about server files can go there.
