Onimusha Way of the Sword Bosses include rival swordsmen, enormous Genma, paired opponents, and returning enemies with expanded attacks. A roster count of 13 distinct boss types is different from a count of 18 rematch entries or a 23-entry sequence that separates repeated encounters and later forms. Use the names and versions below to identify the fight you need, since a familiar opponent can require a different approach on a return appearance.
Boss counts depend on the type of list
The 13-type roster groups encounters by their distinct opponents rather than counting every return battle as a new enemy. The 18-entry approach separates additional enhanced, altered, or paired versions. A longer campaign encounter list can reach 23 entries by splitting repeated fights and stages of the finale into their own positions.
These figures should not be added together or used interchangeably. If you are measuring enemy variety, focus on the roster; if you are checking campaign progress, a repeated Daidara or a later Ganryu fight still matters as another encounter. The sections below organize the main names and their notable variants instead of presenting a single numerical total as a universal answer.
The later sections name late-game opponents and the final boss, so stop at your current encounter if you want to preserve those surprises. Ganryu and Daidara also appear in the expanded demo, making them useful starting points before the campaign's later battles. For help with the underlying defensive actions, keep the combat fundamentals guide alongside this roster.
Sasaki Ganryu
The early Ganryu fight takes place at Kiyomizu-dera and checks whether you can read another swordsman's attacks. His quick swings and less obvious thrust movements can catch a player who attacks whenever Musashi is able to move. Concentrate on recognizing a complete enemy sequence before spending its recovery on your own strikes.
Use sword attacks as your main opportunities to practice parries and deflections, then distinguish his jumping kick and grab from those blade exchanges. Breaking his stamina introduces a much larger opening than the small windows between ordinary attacks. If the timing is still unfamiliar, learn one recognizable sword swing before trying to counter everything with Issen.
Later Ganryu encounters should not be treated as exact repetitions of the first duel. His altered form uses faster, more varied patterns and can punish extended aggression through a countering stance. Shorten your commitments, look for feints, and put more emphasis on creating a stamina break than squeezing an extra hit into every gap.
Daidara
Daidara's club swings give clear visual preparation, but their damage makes careless timing expensive. His charge and subsequent grab also require you to keep reading after the first movement rather than assuming the danger has passed. Dodge the grab and use a confirmed recovery to answer instead of staying close without a plan.
Loose souls are a shared resource in this fight because Daidara can absorb them and become stronger. Gather them when it is safe, particularly after you create a meaningful opening. If you lose resources, a purple Break Issen target can help recover souls, whereas a red target prioritizes direct damage.
Rasho-gan
Rasho-gan combines close-range attacks with projectiles and environmental threats. A red tendril can support his power, and cutting it removes a reason for the fight to become harder than necessary. Keep watching the whole opponent rather than focusing only on the blade closest to Musashi.
When tendrils lift scenery above the arena, use the bow to break those connections before the objects become incoming attacks. The falling debris creates a chance to move back into offense. His spinning attack can return for a second pass, so a successful response to the first spin is not the end of the sequence.
Byakue and enhanced variants
Byakue's axe can hide its actual strike behind spins and flourishes. Wait for the committed attack rather than countering the first preparatory movement. His pounces introduce another reason to separate weapon timing from movements that are better avoided with a dodge.
An enhanced or enraged Byakue becomes more aggressive and can add dangerous grabs and slams. Return appearances therefore deserve a fresh look even if you handled an earlier version comfortably. Keep the aim on breaking stamina without gambling your health on an Issen attempt against every unfamiliar attack.
Ifuu, Burai, and their paired encounter
Ifuu uses wind alongside his close-range weapon attacks. A raised axe at a distance can signal an incoming air wave instead of an ordinary melee swing. When he floats, a bow shot can bring him down and interrupt the threat before it develops further.
Burai brings lightning attacks with his own timing, including crashing movements that can be answered by an appropriate parry or deflection. A precise response can leave him off balance, opening a short opportunity for damage. Learn his recovery separately from Ifuu's rather than transferring one brother's rhythm to the other.
The paired fight changes the problem from reading a single opponent to tracking two overlapping threats. Keep both enemies in view where possible and avoid committing to a long animation while the other brother is free to approach. A short, safe attack sequence is more useful than winning one exchange while taking an unseen hit from the second opponent.
Nue and Greater Nue
Nue mixes claws, movement, and lightning, and some encounters place different colored Nue together. A parry or deflection does not necessarily stagger it, so do not automatically start a long counterattack just because your defensive input succeeded. Reflex Dodge is a useful option when you need to evade and reassess the next movement.
Greater Nue expands the challenge with more varied attacks, including fast swipes, grabs, and attacks that cannot be handled by simply holding block. Watch for the action that follows its first movement and prioritize an answer you can repeat reliably. During a paired encounter, keep enough space to notice the second creature instead of concentrating exclusively on one health bar.
Dohatsu-ten
Dohatsu-ten is a sword duel against an enemy whose blade becomes more dangerous as it lands hits. Letting a short mistake become a series of hits therefore has consequences beyond the immediate health loss. Recover control of the exchange before attempting to reclaim all that damage at once.
Successful parries and deflections can create small openings, but the enemy may continue attacking after a clash. Remain ready for the next strike rather than reading every spark as a stagger. Blade Barrages can emerge during these close exchanges, so remember the light-and-heavy attack alternation that resolves them.
Benkei and the full arsenal version
Benkei's armor and heavy attacks make him an intimidating opponent, but his attack preparation gives opportunities for deliberate counters. Missing those timings is costly, and his powered-up state increases the pressure. Use the available Pillar power against his armor rather than assuming ordinary damage is your only way through his protection.
The full arsenal version adds ranged weapons to the encounter. Bow shots can interrupt cannon attacks, while thrown axes require their own defensive timing. Treat the added range as a change in the fight's structure: retreating now has different risks from stepping away during the earlier battle.
Shuten Doji
Shuten Doji's later form makes resource preservation especially important. Healing spent during the first part of the fight is not automatically refunded when the next phase begins. Aim to finish the earlier exchanges with enough reserves to learn the changed threats instead of using every recovery item to force quick progress.
The encounter also brings Musashi's Awakened Onimusha form into play. Use its active period for attacks you can land, keeping your attention on the opponent rather than assuming transformation removes the need to defend. A bow shot to Shuten Doji's head can interrupt a dangerous later attack, giving the ranged weapon a practical role amid the larger spectacle.
Dokyo
Dokyo creates pressure through projectiles and other disruptive attacks. A well-timed Issen against an incoming projectile can interrupt a longer ranged sequence, giving you a way to regain initiative. Do not let the volume of effects convince you that every moment requires a forward rush.
When exploding Genma appear, their position relative to Dokyo matters. Baiting their explosions near her turns the additional enemies into an opportunity. Leave enough room to escape the detonation yourself rather than following them into damage just to remain within sword range.
Minamoto no Yoshitsune
Yoshitsune is the final sustained test of the game's defensive vocabulary, with a sequence that develops into later forms and phases. Sword attacks, kicks, grabs, and ranged threats each demand attention, and a successful response to one does not solve the entire pattern. Conserve enough healing and resources to reach the later portions with room for mistakes.
Watch for the shoulder-tapping katana preparation before a fast dash, and remain alert to kicks when you are expecting another weapon swing. During the armored finale, ordinary attacks eventually stop being enough to deal the required health damage. Build toward Oni Awakening through stamina breaks and soul collection, then use the transformed state to make progress.
A final boss attempt becomes easier to diagnose when you identify the specific move or resource shortage that ended it. Practice that part of the encounter instead of replacing every element of your approach after one loss. The difficulty settings guide and Issen timing guide help separate mode selection from the defensive skills you are still learning.
Return to cleared arenas for enemy notes
Finishing a boss does not always exhaust the reason to visit its arena. Genma Notes can appear in hidden chests associated with defeated bosses, and the Gauntlet's blue glow helps signal their presence. Return when convenient, use Oni Power to reveal the chest, and include these visits in your trophy cleanup plan.
