Core Features of the Mules Slayer Addon (26.x, 1.21) – MCPE/Bedrock Demon Slayer Mod
When we first loaded into a world with the Mules Slayer Addon (26.x, 1.21) – MCPE/Bedrock Demon Slayer Mod, the first thing we noticed was how much it changes the identity of your character. Unlike standard survival where everyone starts the same, this mod introduces a heritage system. You aren’t just a “Steve” or “Alex” anymore; you are a member of a specific lineage with innate powers.
The addon features 15 distinct families. Upon your first join, the game randomly assigns you to one. This isn’t just for show—each family comes with specific perks that can drastically change your early-game survival. For instance, some families might grant a massive 100% damage boost, while others focus on critical hit chance or health regeneration. If you enjoy this type of power-scaling, you might also want to check out the Jujutsu Kaisen Addon 26.x 1.21 for MCPE Anime Powers Domain Combat for a different flavor of anime combat.
Beyond heritage, the combat itself is overhauled. You aren’t just clicking as fast as you can. The addon introduces a 5-hit combo system for swords, making fights feel more like an action game. Whether you are hunting demons in the dark or dueling friends, the mechanical depth here is impressive for a Bedrock mod.
The Family System and Genus Bonuses
The “Genus” or family system is the backbone of your character’s progression. We’ve found that the randomness adds a fun “gacha” element to starting a new world. Here are some of the standout families you might roll:
- Kamado Family: Offers a boost to critical damage, reflecting the protagonist’s resilience.
- Tsugikuni Family: Widely considered the “jackpot” roll, providing a staggering +100% damage bonus.
- Rengoku Family: Focuses on aggressive buffs suitable for those who want to master Flame Breathing.
- Tokyo/Other Families: Provide various utility bonuses like speed or resistance.
If you aren’t happy with the family the universe gave you, don’t worry! We found that you can reset your family using Heavenly DNA, which is obtained by crafting or using a Nether Star. For those who prefer a more direct approach (and have cheats enabled), you can use the scoreboard command: /scoreboard players set @s family [0-14]. This allows you to manually pick the lineage that fits your desired playstyle.
Nichirin Swords and Combat Mechanics
You can’t call yourself a Demon Slayer without a Nichirin Sword. In the Mules Slayer Addon (26.x, 1.21) – MCPE/Bedrock Demon Slayer Mod, these aren’t just retextured iron swords. They are specialized tools required to actually kill the demons that haunt your nights.
To get your hands on one, you’ll need to craft Scarlet Ingots. This is done by combining iron, redstone, and glowstone. Once you have your blade, the fun begins. The swords feature a unique 5-hit combo system that triggers dynamic animations.
One of our favorite features is the Haganazuka NPC. By interacting with this swordsmith, you can customize the color and style of your blade. If you hold the sword and sneak, you can often toggle between different visual styles or elemental effects. Demons in this mod have a hefty 200 HP and a natural resistance to standard weaponry; if you aren’t using a Nichirin blade, you’re going to have a very bad time.
Mastering Breathing Styles and Progression
Breathing Styles are the heart of the anime, and they are executed beautifully here. You don’t just start knowing how to use Water Breathing. You have to earn it. There are over 6 breathing styles currently available, including Water, Flame, Wind, Thunder, Mist, and Insect. Each style feels distinct, with its own set of “Forms” that act as special abilities.
If you’re looking for more RPG-style progression in your Minecraft world, the Solo Leveling Map Addon 1.21 1.20 for MCPE RPG Anime Mod offers a similar sense of growth and power fantasy.
| Breathing Style | Key Feature | Best For |
|---|---|---|
| Water Breathing | Includes the 11th Form: Dead Calm | Defensive play and crowd control |
| Flame Breathing | High burst damage (9th Form) | Fast, aggressive eliminations |
| Thunder Breathing | Extreme mobility and speed | Quick strikes and dodging |
| Wind Breathing | Wide area-of-effect attacks | Fighting multiple demons at once |
Unlocking Skills in the Mules Slayer Addon (26.x, 1.21) – MCPE/Bedrock Demon Slayer Mod
Progression in the Mules Slayer Addon (26.x, 1.21) – MCPE/Bedrock Demon Slayer Mod is tied to your experience. To unlock a breathing style and its subsequent forms, you need 15 Skill Points.
How do you get these points? You convert your earned XP into Skill Points using specialized “Breathing Books.” This creates a satisfying gameplay loop: hunt mobs, gather XP, convert it, and unlock a more powerful move. Higher forms, like the Water 11th Form or Flame 9th Form, require you to master the basics first. We recommend focusing on one style at a time until you’ve unlocked the ultimate forms, as they provide the best utility against high-level bosses.
Demon Transformations and Blood Demon Arts
For those who want to walk a darker path, the addon allows you to become a Demon yourself. This changes the gameplay entirely. As a demon, you gain a massive 200 HP pool and access to Blood Demon Arts—supernatural abilities that rival breathing styles.
However, being a demon comes with a catch: Daylight Weakness. Just like in the anime, if you step into the sun without protection, you will begin to burn. This forces a nocturnal playstyle that is both challenging and rewarding. You can use commands to trigger the demon transformation, allowing you to test out characters like Akaza or Rui.

Step-by-Step Installation Guide for Minecraft 1.21
Installing the Mules Slayer Addon (26.x, 1.21) – MCPE/Bedrock Demon Slayer Mod is straightforward, but you must be careful with your world settings. Because this mod uses custom scripts and complex entities, standard world generation in Minecraft Bedrock Edition isn’t enough.
Follow these steps to install:
- Download the Files: Grab the Behavior Pack (BP) and Resource Pack (RP) from our links.
- Import to Minecraft: Open the
.mcpackfiles. Minecraft should launch and say “Import Started.” - Create a New World: We always recommend a fresh world to avoid conflicts.
- Enable Experimental Settings: This is the most important part. You must toggle on:
- Holiday Creator Features
- Upcoming Creator Features
- Beta APIs (Script API)
- Molang Features
- Apply Packs: Go to the “Resource Packs” and “Behavior Packs” tabs in your world settings and activate the Mules Slayer packs.
- Play: Once the world loads, you should see a message about your assigned family!

Troubleshooting the Mules Slayer Addon (26.x, 1.21) – MCPE/Bedrock Demon Slayer Mod
If the mod isn’t working—for example, if the swords don’t have textures or the breathing styles don’t appear—the issue is almost always the Experimental Toggles. Double-check that “Beta APIs” is turned on, as this addon relies heavily on the Script API to handle the 5-hit combos and XP conversion.
Performance can also be an issue on older mobile devices. Since the addon adds many high-quality animations and custom entities, we suggest increasing your memory allocation in the Minecraft settings if you experience lag.

Frequently Asked Questions about Mules Slayer
How do I change my family in the addon?
You can change your family by using Heavenly DNA (crafted with a Nether Star) or by using the command /scoreboard players set @s family [number]. There are 15 families (0 through 14) to choose from.
Can I use Breathing Styles as a Demon?
Generally, no. The addon separates Slayers and Demons. Slayers use Breathing Styles, while Demons utilize Blood Demon Arts. Choosing one path usually locks the other to maintain the roleplay balance of the anime.
Why aren’t my Nichirin swords doing damage to mobs?
Nichirin swords are specially designed to fight Demons. While they work on vanilla mobs, their primary “bonus” is being the only weapon capable of permanently killing the 200 HP Demons. If they aren’t working at all, ensure your Behavior Pack is active and Experimental Settings are enabled.
