Onimusha Way of the Sword Boss Guide

Boss fights in Onimusha: Way of the Sword are won by breaking posture, not just draining health. This guide covers all 18 main boss fights with per-attack answers (parry or dodge), the Break Issen timing, and what each boss rewards. It also covers the Boss Rematch mode and Carnage difficulty.

How Boss Fights Work

• Break posture first: parrying and deflecting drains the enemy stamina gauge faster than damage does. A broken posture opens the Break Issen finisher.
• White-glowing attacks cannot be Issen’d — parry or deflect them, or dodge.
• Bosses regenerate stamina at range — keep the pressure on.
• Blazing Gauge: landing attacks fills the gauge; spend it on Oni Armaments and Oni Awakening for burst phases.
• Grab attacks cannot be parried — watch the telegraph and dodge.

Sasaki Ganryu (Kiyomizu-dera)

The first major boss, also the demo’s finale. Ganryu fights with a long sword and is the game’s parry tutorial boss.

• Phase 1: parry his sword strings. His jump kick has too short a parry window — side-dodge it.
• Phase 2 (below ~50% HP): longer combos, more kicks, and a command grab telegraphed by a flashing left hand — dodge it.
• Cinematic blade clashes: alternate one-handed and two-handed attacks to win them.
• When his posture breaks, finish with Break Issen.

Daidara (The Stage Is Set at Kiyomizu)

• Absorb every floating soul immediately — souls you leave on the ground get eaten by Daidara and power him up (Blazing State).
• His slow mace swings are highly telegraphed: parry them and punish the recovery.
• His charge: dodge sideways, never backwards.
• Phase 2 hand-grab: deflect it, then counter-attack.

Rasho-gan (Careful What You Wish For)

• Open with Oni Vision: find the red tether lines and shoot them with the Oni Bow to weaken him.
• Parry his Malice projectiles.
• Phase 2: he throws trees — use a perfect dodge (Reflex) and stay mid-to-close range so his barrage whiffs.

Ifuu & Burai (Windswept Kennin-ji / Late-Game Duo)

• Ifuu (club): deflect his club swings to drain his stamina; dodge his wind spells and punish after every deflected blow.
• Late game, Ifuu and Burai fight together — separate them with movement and focus one down first.

Greater Nue (Oikeniwa Pond)

• Hold mid-range and deflect its lightning bolts back — a returned bolt stuns it.
• Bait the tail slam, then punish with two-handed heavies to sever the tail — this removes attacks and stuns it again.
• Phase 2 (high-voltage state): switch to the Earth-Shaker hammers to strip its stamina faster.

Shuten Doji (Mt. Oe — the Gourd Drainer)

• His gourd is the fight: every successful drink permanently powers him up. Interrupt it every time — shoot the gourd with the bow, or unload melee.
• Most of his attacks are dodge-bait, not parry-bait — stay mobile.
• Phase 2: he enters an Ultimate Mode; save your Blazing Gauge and Oni Awakening to answer it.

Dohatsu-ten (Recurring — The Roots of All Evil)

• Parry his standard sword attacks; his grabs cannot be parried — dodge them.
• When he raises his guard, break it with Triangle + Circle.
• His vocal callouts ("No escape", "Shatter"…) are attack tells — learn them.
• Each win drops Dohatsu-ten’s Bone ×2 — he is a repeatable upgrade farm.

Byakue, Benkei, Dokyo & the Final Boss

• Byakue: a giant axe-wielder with no dedicated arena; he grows more aggressive as the fight goes on — match his aggression with parries.
• Benkei: fought once mid-game and rematched late — treat him like Ganryu: parry strings, dodge grabs.
• Dokyo: a late-game encounter tied to the story’s curse — keep mid-range and punish spell wind-ups.
• Minamoto no Yoshitsune (final boss): the last fight of The Clash at Rendaino. Bring maxed gear and plenty of healing; expect multi-phase pressure and Issen-check attacks.

Boss Rematch Mode & Carnage Difficulty

After the story, a Boss Rematch mode lets you refight all 18 bosses on three difficulty tiers — it is the core of the hardest trophy in the game, Glutton for Punishment (see the Trophy Guide). Carnage, the highest difficulty, is unlocked in New Game+ and re-tunes every fight around defensive posture play, Break Issen, and the Blazing Gauge → Oni Armaments → Oni Awakening chain. The Carnage-completion reward weapon makes the rematch grind far easier — a strong argument for clearing Carnage first.
