Initial Awakening and the Path of the Slayer

The journey through the demonfall storyline begins with a harrowing cinematic experience where your family is attacked. This serves as the catalyst for your character's growth, whether you choose the path of a Human or eventually descend into becoming a Demon. For those pursuing the Slayer path, the initial encounter with the starter demon is your first test of combat proficiency.

Video Highlights:

  • Demonstrating the extreme speed and power of the Yoriichi Spec during early missions.
  • Navigating the initial family house and the first demon encounter.
  • Interacting with key NPCs like Miranda to reset or begin the journey.
  • Efficiently clearing the early dialogue sequences to reach the training phase.

After the tragedy, you must make your way to the nearest village. The soup shack interaction is a notable milestone, where you encounter the "Mean Lady" NPC. This sequence leads into the introduction of the Rengoku family dynamics, setting the stage for your eventual training and entrance into the Demon Slayer Corps.

If you are using a high-tier Spec like Yoriichi, your walk speed is significantly boosted. Use this to sprint past non-essential mobs in the early game to reach Urokodaki faster.

The Slayer Exam and Final Selection

To progress through the demonfall storyline, every aspiring Slayer must pass the Final Selection. This grueling exam takes place in a demon-infested forest where survival is the only goal. You are required to eliminate a specific number of demons to prove your worth to the Corps.

1

Locate Urokodaki

Find Akira Urokodaki to initiate the quest for the Final Selection. He will provide the necessary guidance and the iconic mask required for the exam.

2

Enter the Forest

Travel to the exam site. Once inside, you cannot leave until the objective is met or you are defeated.

3

Demon Cull

You must defeat 30 demons in total. This includes standard demons and the more dangerous Blue Demon, which possesses higher health and stronger attacks.

4

Completion

After securing 30 kills, return to the exit to receive your Demon Slayer uniform and your first official rank within the organization.

Demon TypeDifficultyStrategy
Standard DemonLowBasic M1 combos and heavy attacks
Blue DemonMediumUse breathing techniques to break guard
Group MobsHighAoE skills like Clear Blue Sky are essential
Exam Requirements

Do not attempt to exit the forest before reaching the 30-kill threshold. The game tracks your progress, and leaving early will result in a failed attempt, forcing you to restart the exam.

Confronting the Lower Moons

Once you have joined the Corps, the demonfall storyline shifts toward high-stakes missions assigned by Kagaya Ubuyashiki. These missions involve defending innocent civilians and hunting down the Twelve Kizuki. The difficulty spikes significantly as you encounter bosses with unique Blood Demon Arts.

Akuro (Lower Moon 6)

  • Location: Final Selection follow-up
  • Difficulty: Moderate
  • Key Tip: Focus on leg strikes to limit mobility

Rui (Lower Moon 5)

  • Location: Natagumo Mountain
  • Difficulty: High
  • Key Tip: Hug the left wall to skip to the boss room

Lower Moon 2

  • Location: Final Story Chapter
  • Difficulty: Extreme
  • Key Tip: Requires perfect parrying and stamina management

The fight against Akuro serves as your introduction to boss mechanics, requiring you to dodge telegraphed attacks and exploit openings. Rui, however, introduces long-range thread attacks that can trap and drain your health quickly. The Lower Moon 2 encounter is currently the pinnacle of the storyline progression, testing everything you have learned about your chosen Breathing Style.

Akuro~1,500 HPEXP, Yen, Slayer Rank Up
Rui~2,500 HPMassive EXP, Rare Materials
Lower Moon 2~4,000 HPTop-tier EXP, Story Completion
Combat Efficiency

Using Sun Breathing techniques like "Solar Heat Haze" or "Clear Blue Sky" provides the best damage-to-stamina ratio for boss fights. Always maintain at least 20% stamina to ensure you can dash away from ultimate attacks.

Village Defense and Corps Missions

Between major boss fights, the demonfall storyline requires you to complete various corps missions. These missions often involve traveling to villages under attack. Kagaya Ubuyashiki will summon you to the headquarters to provide briefings on these emergencies.

Mission Objectives:

  • Speak with Kagaya Ubuyashiki at the Corps HQ
  • Travel to the attacked village near the headquarters
  • Eliminate all invading demons (approx. 10-15)
  • Protect the remaining innocent villagers
  • Return to HQ for the next assignment

The Village Defense mission is a test of endurance. Demons will spawn in waves, and you must clear them efficiently to prevent the NPC "innocent" count from dropping too low. This mission is a prerequisite for unlocking the Rui boss fight and further progression into the late-game content.

Interior Sweep10 DemonsProtect the village center

NPC Interactions

When Kagaya calls you "My Child," it signifies your rising status within the Corps. These dialogue sequences are essential for unlocking the higher-difficulty mission tiers.

Advanced Progression and Specs

Reaching the end of the current demonfall storyline allows players to focus on refining their builds. For those lucky enough to obtain the Yoriichi Spec, the gameplay changes from a struggle for survival to a dominant power fantasy. The stats provided by this spec are unparalleled in the 2026 meta.

AttributeStandard SlayerYoriichi Spec
Max HP100 - 300550
Max Stamina100 - 200500
Walk SpeedBaseEnhanced (Sonic Speed)
Unique SkillNoneSun Breathing Mastery

To maintain this power, players must continuously farm the Lower Moon bosses for experience. Even after completing the main story, the "Lower Moon 2" fight remains the most efficient way to reach the level cap and prepare for future content updates involving the Upper Moons.

Farming Loop

Once the storyline is finished, the best loop for EXP is: Lower Moon 2 -> Rui -> Village Defense. This cycle maximizes your EXP per hour while keeping your Yen reserves high for rerolls.

Conclusion & FAQ

The demonfall storyline is a comprehensive journey that takes you from a novice survivor to a master swordsman. By following the structured path of the Slayer Exam, mastering the Village Defense missions, and systematically defeating the Lower Moons, you can achieve the highest ranks within the game.

Q: How many demons do I need to kill for the Final Selection?

You must defeat exactly 30 demons within the forest to pass the Slayer Exam and progress in the storyline.

Q: Where can I find the boss Rui?

Rui is located at Natagumo Mountain. You can skip most of the mountain path by hugging the left-hand wall to reach his boss arena directly.

Q: What is the final boss currently in the Demonfall storyline?

As of the latest 2026 updates, the final major encounter in the storyline is the fight against Lower Moon 2.

Final Note

Always ensure your game is saved by interacting with the designated NPCs after major boss fights. If the game fails to teleport you back to the HQ after Lower Moon 2, a quick rejoin usually fixes the progression flag.
