demonfall agatsuma clan Overview & Sleepy Awake Ability
The demonfall agatsuma clan is one of the most coveted family lineages in the game, boasting a rare 2% roll rate. Inspired by the legendary Zenitsu Agatsuma, rolling this clan instantly equips your character with Zenitsu's signature hair wig and grants access to one of the most powerful comeback mechanics in the game: the Sleepy Awake ability.
This passive-active hybrid skill activates automatically when your character is knocked down in battle. Upon triggering, your character enters a berserk state for 45 seconds, during which your total damage output is increased by 50%. This makes the clan exceptionally lethal in both high-stakes Player vs. Player (PVP) encounters and difficult Player vs. Environment (PVE) boss fights.
Sleepy Awake Buffs
- 50% damage increase
- Automatic recovery from knockdown
- High-intensity electrical visual aura
Combat Drawbacks
- Halves current health upon trigger
- High risk of death if comboed
- Requires precise defensive play
Build Synergy
- Perfect fit for Thunder Breathing
- Maximizes rapid thrust attacks
- High-risk, high-reward playstyle
Video Highlights:

- Walkthrough of the entire Thunder Breathing questline.
- Showcases the high-damage output of the Sleepy Awake ability.
- Strategies for taking down story bosses like Rui and Kaigaku.
Because Sleepy Awake automatically halves your remaining health when it activates, triggering it at low health can leave you extremely vulnerable. Always ensure you have a defensive plan or a quick escape route ready when the berserk state begins.
How to Learn Thunder Breathing
To maximize the potential of the demonfall agatsuma clan, you must pair it with Thunder Breathing. This breathing style is taught by Kojima, the retired lightning hashira, who resides in a remote house within the Coast Forest. Before you can speak to him, you must prepare a substantial amount of resources to satisfy his training requirements.
First, travel to Okia Village and purchase 20 delicious soups from the local soup shop, which will cost you a total of 400 Yen. Additionally, you must accumulate 4,000 Yen to pay Kojima's final instruction tax. Once you have gathered these resources, make your way to Falls Bridge and take a detour to find his hidden cabin.
| Quest Step | Objective Details | Requirements | Key Rewards |
|---|---|---|---|
| Step 1 | Purchase food from Okia Village | 20 Delicious Soups (400 Yen) | Quest items secured |
| Step 2 | Deliver soups to Kojima | Visit Coast Forest cabin | Quest progression |
| Step 3 | Deliver confidential message | Travel to Slayer Headquarters | Find Maron NPC |
| Step 4 | Pay the final training tax | Return to Kojima with cash | Thunder Breathing unlocked |
After completing Kojima's errands and paying the fee, you will unlock the basic forms of Thunder Breathing. To make this style viable for continuous combat, you must also obtain infinite breathing. Travel to the Stone Person NPC and purchase a training rock for 300 Yen. Hold this rock continuously for approximately 10 minutes until your stamina no longer drains, granting you infinite breathing capacity.
Collect all 20 soups and the 4,000 Yen before you ever visit Kojima. This saves you from having to run back and forth across the map, which can easily take up to 30 minutes of real-world time.
Thunder Breathing Skill Tree & Forms
Thunder Breathing relies on lightning-fast strikes, rapid gap closers, and high-frequency combos. When combined with the 50% damage boost from the demonfall agatsuma clan's Sleepy Awake skill, these moves can shred an opponent's health bar in seconds.
Below is a detailed breakdown of the primary forms available in the Thunder Breathing skill tree, along with their damage profiles and recommended tactical uses.
| Form Name | Skill Description | DPS Rating | Tactical Best Practice |
|---|---|---|---|
| 1st Form: Thunderclap | Rapid linear dash and slash | High | Ideal for initiating combos or chasing runners |
| 1st Form: Six Fold | Six consecutive teleport strikes | Very High | Excellent for crowd control and dodging |
| 2nd Form: Rice Spirit | Multi-directional electrical slash | Moderate | Use defensively to deflect incoming melee |
| 3rd Form: Thunder Swarm | AOE electrical field burst | High | Great for breaking enemy blocks up close |
| 5th Form: Heat Lightning | Long-range electricity projectile | Moderate | Perfect for poking enemies from a safe distance |
To unlock these forms, you must earn skill points by leveling up. Farming upper moon bosses like Gyutaro is the most efficient way to gain experience quickly. Once you reach level 50, you will have enough points to fully max out your breathing forms, sword mastery, and physical attributes.
The First Form: Thunderclap and Flash is your bread-and-butter move. It has a incredibly short startup time, making it nearly impossible for opponents to react to when executed immediately after a successful block or dodge.
Forging the Thunder Nichirin Blade
A true Agatsuma build is incomplete without the custom Thunder Nichirin blade. This weapon provides a significant boost to your base slashing damage and infuses all your basic attacks with electrical elements. Crafting this blade requires completing the Slayer Exam and gathering several rare materials.
Pass the Slayer Exam
Travel to the Glina Forest and speak to the examiner. You must survive and defeat 30 demons before the timer reaches zero. Watch out for the blue demon, as it is highly aggressive. Passing the exam awards you the standard Slayer uniform and a base Nichirin blade.
Mine Sun Ore
Purchase a pickaxe for 500 Yen from any major village merchant. Travel to the mountain cliffs near Falls Bridge and mine the glowing ore veins to collect at least 20 pieces of Sun Ore.
Acquire Crystal Essence
Obtain a Crystal Essence by defeating cavern bosses or trading with other players. This is a rare drop, so trading is often the fastest method if you have spare trinkets.
Farm 10,000 Yen
Search the map for Perfect Crystals, which sell to merchants for 6,000 Yen each. Combine this with general trinket farming to quickly accumulate the required 10,000 Yen forging fee.
| Crafting Ingredient | Required Quantity | Primary Acquisition Method |
|---|---|---|
| Slayer Nichirin | 1 | Base reward for passing the Slayer Exam |
| Sun Ore | 20 | Mined from mountain cliffs |
| Crystal Essence | 1 | Cavern boss drop or player trading |
| Yen | 10,000 | Selling Perfect Crystals and trinkets |
Once you have all the ingredients, return to the blacksmith at the Slayer Headquarters to forge your yellow-tinged Thunder Nichirin.
Essential Progression Milestones:
- Roll the Agatsuma clan using spins or Robux
- Learn Thunder Breathing from Kojima in Coast Forest
- Complete the Stone training to unlock Infinite Breathing
- Pass the Slayer Exam in Glina Forest
- Forge the Thunder Nichirin blade
The Thunder Nichirin blade not only boosts your overall DPS but also increases the stun duration of your heavy attacks, allowing you to chain your breathing forms together much more fluidly.
Boss Battle Tactics & Progression Route
To test the limits of your demonfall agatsuma clan build, you must progress through the main story campaign. The campaign features several iconic bosses that require specific tactical approaches to defeat.
Lower Moon 6 (Cavern Boss)
This massive boss is slow but hits incredibly hard. His fire breath can deal continuous damage if you get trapped. To defeat him easily, bait out his fire breath, dash behind him using Thunderclap and Flash, and execute your full combo. When he enters his rage phase, back away to avoid his explosive AOE slam.
Lower Moon 5 (Rui)
Rui uses thread-based attacks that can trap you from a distance. Maintain a defensive posture and block his initial thread strikes. Once his attack sequence ends, use your gap closers to get close and unleash your high-damage forms.
Lower Moon 2
This is one of the most challenging fights because of his stamina-draining aura. He will constantly deplete your stamina, preventing you from running or executing skills. If you get knocked down, let Sleepy Awake activate to instantly recover with a 50% damage boost, then quickly finish him off before the buff expires.
| Boss Name | Threat Level | Key Attack to Avoid | Winning Strategy |
|---|---|---|---|
| Lower Moon 6 | Low | Continuous Fire Breath | Dash behind during fire breath; punish slow turn speed |
| Rui (Lower Moon 5) | Medium | Thread Trap & Ranged Slashes | Block thread strikes; close distance with Thunderclap |
| Lower Moon 2 | High | Stamina Drain Aura | Leverage Sleepy Awake knockdown buff to burst down |
| Kaigaku | Very High | Dark Thunder Breathing | Use shoulder bash to break guard; dodge AOE strikes |
During the Kaigaku fight, do not attempt to trade blows directly. His Dark Thunder Breathing has superior reach and can easily interrupt your skills. Instead, wait for him to finish his skill animations before counter-attacking.
