Nioh 3 Ryomen Sukuna Boss Guide: Conquer the Two-Faced Demon

Ryomen Sukuna stands as one of Nioh 3’s most distinctive boss encounters—a two-headed, four-armed yokai that prevents traditional backstabbing tactics with its unusual anatomy. Found during the “Fated Land” myth quest in Iinoya (Warring States, 1572 CE), this ghost of a betrayed Ii clan retainer tests your mastery of Burst Break counters and elemental strategy. Here’s your complete battle plan to defeat this legendary demon and claim victory alongside Ii Naotora.

Nioh 3 Boss Overview & Preparation

Understanding Ryomen Sukuna’s Two-Sided Nature

Sukuna’s form consists of two demons joined back-to-back—a red half wielding sword and axe with fire abilities, and a blue half carrying a bow with ice/water attacks. Both halves share one health bar but act independently, creating unpredictable attack patterns.

Critical Strategy: Focus on the blue (bow) side at the fight’s start. While it peppers you with ice arrows at range, the red side launches frustrating ground fire columns that are harder to predict. Draw the blue side’s aggro so Naotora occupies the more dangerous red half.

Elemental Preparation: Avoid equipping fire or ice damage weapons—Sukuna resists both elements. Instead, use physical damage or alternative elements like lightning.

Phase 1: Blue Side Priority & Arrow Patterns

Start by positioning yourself toward the blue side and baiting its ranged attacks.

Blue Side Tactics

Ice Arrow Attacks: Easily blocked or rolled through with proper timing. Watch Sukuna draw the bow back—when you see the pull animation, go defensive.

Spiral Arrow (Special): This variant features a spiral visual effect when drawn. It leaves Sukuna vulnerable after firing, creating your damage window. Attack immediately after the shot, never during the aim.

Mid-Range Positioning: Stay at medium distance. Too far triggers spell spam; too close activates the red side’s axe combos.

The goal is maintaining pressure on the blue side while Naotora diverts the red side’s attention. If you’re struggling with aggro management, consider summoning an additional companion through the game’s multiplayer systems to guarantee split attention.

The Burst Break Counter: Your Win Condition

Sukuna’s defining weakness is his telegraphed Burst Attack—a spinning tornado charge where he twirls toward you while rotating his weapons.

Burst Break Execution

1. Start in Samurai Style for optimal Burst Break positioning
2. Watch for the Red Aura surrounding Sukuna (Burst Attack indicator)
3. Time your R2 press just as the tornado attack connects
4. Land the counter to stun Sukuna for several seconds and drain massive Ki
5. Switch to Ninja Style immediately after the stun
6. Unleash fast weapons during the stun window to burn remaining stamina
7. Execute critical hit once Ki is depleted for massive damage

This single combo sequence can remove 20-30% of Sukuna’s health bar. Repeat this pattern throughout the fight—bait Burst Attack, counter, punish, reset.

Phase 2: Yokai Realm & Extended Combos

After dealing sufficient damage, Sukuna enters the Yokai Realm (his “Dark Realm”), beginning with an aggressive red-side combo.

Survival Strategy: Run immediately when he enters this phase. His Dark Realm moves feature longer attack chains with the red side, but the attacks themselves remain highly telegraphed and easy to dodge.

Living Artifact Timing: Save your Living Artifact and Soul Core abilities for after he exits the Yokai Realm. The Dark Realm moves are straightforward to avoid, so there’s no reason to force him out early.

Advanced Tactics: Parries & Positioning

The red side is highly susceptible to Deflect/Parry mechanics, making Sekiro-style parry builds extremely effective.

Red Side Parry Windows: His regular melee swings are slower than they appear, giving you generous parry timing. A parry-focused build can trivialize the red side entirely.

Side Attack Strategy: While you can’t hit Sukuna from behind (no back exists), his sides offer safer attack angles. The red side’s weapon arcs have smaller hitboxes from the sides versus frontal assault.

Sweet Spot Positioning: Maintain mid-range where the red side keeps swinging but you’re outside axe spin reach. This creates consistent Burst Attack bait opportunities.

Attack Pattern Breakdown

Red Side (Fire)

• Four-hit sword slash combo (guardable)
• Simultaneous sword and axe advance (heavy damage, dodge when stance changes)
• Ground fire column projectiles (medium range)
• Tornado Burst Attack (counter opportunity)

Blue Side (Ice)

• Standard ice arrows (blockable)
• Spiral arrow variant (leaves vulnerability)
• Wide-area ice magic (dodge opposite direction)
• Bow melee strikes at close range
