All Bosses in Onimusha: Way of the Sword (Counts, List & Prep)
How many bosses are in Onimusha: Way of the Sword: 13 unique bosses, 18 Boss Rematch entries, and roughly 36 fight encounters — every named boss so far, with links to full fight guides.
Short answer: how many bosses are there?
Three numbers get quoted for Onimusha: Way of the Sword, and all of them are correct — they just count different things:
~13 unique bosses
18 entries in the Boss Rematch menu
~36 boss fight encounters across a full playthrough (repeat appearances included)A story-focused run sits around 20–25 hours, so you will meet several of these fights more than once. [MULTI-PLAYER] Counts cross-checked across post-launch guides (Timesaver, IGN, Rock Paper Shotgun) — see the evidence note at the bottom.

[WALKTHROUGH-LISTED] = named in the IGN walkthrough checklist, which is still being filled in (“more coming soon”), so treat the tail of this list as in progress rather than exhaustive. The remaining fight or two before the count reaches 13 has not been reliably named yet — we will add it once it can be cited.
If you came here looking for Yoshitsune or Benkei strategy: those pages get published when the fights can be described move-by-move without guessing. The two fights we can already break down properly are below.
Sasaki Ganryu — the duel that teaches the game
The Kiyomizu-dera duel is where regular-enemy habits stop working. It tests clean reads, parry discipline, and not overcommitting after one hit. You fight him again much later in “To Live is to Suffer”, so the lesson compounds.
Prep: land reliable defensive answers first. Full notes: Sasaki Ganryu boss guide
Daidara — the fight that races you for souls
A large club-and-charge fight where the boss can absorb the same soul drops you are hunting. If it feeds, it powers up — the follow-up is to punish the enlarged stomach when a real opening appears.
Prep: spacing and resource discipline beat greedy absorbs. Full notes: Daidara boss guide — and read how souls work before this fight, because it turns absorption into a tug-of-war.
Preparing for the rest of the roster
Most of the mid-game bosses lean on systems you have already met:
- Skills carry fights, not stats. Power Stones and Oni Stones unlock skills, Red Souls enhance them — see the stones & skills guide. You cannot max the Oni skill tree in one playthrough, so pick deliberately.
- Scouting attempts are not failed attempts. First clears are for learning what the boss is testing — patience, spacing, or a system check.
- Do not confuse a stylish Issen with the correct answer. A clean parry string usually beats one risky timing read.
- After a bad hit, reset. Panic strings lose more fights than the first mistake does.
Boss Rematch, in one paragraph
Post-launch guides describe a Boss Rematch menu with 18 entries — repeat story appearances plus rematches of the same boss. It exists for practice and score-chasing on fights you have already cleared. Exact unlock rules and difficulty modifiers are still being verified.
Evidence & update notes
- Boss counts (13 unique / 18 rematch / 36 encounters): [MULTI-PLAYER] — Timesaver.gg post-launch breakdown, consistent with IGN’s in-progress checklist.
- Named list: [MULTI-PLAYER] IGN walkthrough + our own fight guides; Shuten Doji via official trailers [OFFICIAL]; Yoshitsune currently [SINGLE-SOURCE] to Timesaver’s guide.
- The demo’s hidden Byakue Special Challenge (unlocked by landing 10 Issen counters in the demo build) is documented separately from the story roster; how it maps to the release version is still [UNVERIFIED].
