Onimusha: Way of the Sword Walkthrough — All 22 Main Missions

Short answer

Onimusha: Way of the Sword is built from 22 main missions, not numbered chapters. A story-focused run takes about 20–25 hours depending on difficulty; side content pushes a fuller playthrough toward 30+ hours. The final mission, The Clash at Rendaino, triggers a point of no return — finish your Kyoto business before you start it.

[MULTI-PLAYER] Length figures converge across G2A, TimeSaver, and Dot Esports post-launch coverage; mission list from Space4Games’ progress guide.

Boss placement follows walkthrough coverage: Ganryu at Mission 2, the Oni Refuge stretch around Mission 7, and the Ganryu rematch at Mission 16. The remaining bosses land inside these missions too — the full per-mission boss map is being filled in as fights are documented.

If you played the demo

The public demo covered the game’s opening stretch: the Kiyomizu-dera grounds and the Sasaki Ganryu stage duel. Nothing from the demo carries over — the release version starts fresh at Mission 1 — but the combat instincts do. If you cleared the demo, the first real wall is still Ganryu, and the parry discipline you built is the right tool for him.

Reading order for new players

1. Beginner guide — first-hours habits
2. Combat guide — parries, Issen timing
3. Stones & skills guide — what to unlock first, because you cannot max the tree in one run
4. Souls guide — the absorption habit that pays off from Mission 7 onward
5. This hub for mission order, then the bosses hub when a wall hits

Kyoto is a hub, not an open world

After the linear opening, Kyoto becomes a larger zone you revisit as abilities unlock. Civilian rescues, blocked corruption routes, and shrines are the reasons to come back between missions. If a path looks sealed, look for Oni Bow interactions or environmental tells before assuming you missed a key — and see the Kyoto exploration and upgrades guide for what is worth doing between missions.

If you are stuck

Symptom	First thing to try
Dying to regular enemies	Slow down; parry one telegraphed swing instead of trading hits
Ganryu feels unfair	Scout two attempts, then commit to deflect timing under pressure
Path looks sealed	Check for Oni Bow / environmental tells first
Boss deletes you in one string	Treat the first attempts as scouting; spend Red Souls on a defensive skill
Mid-game damage feels too low	You are probably skipping skill unlocks — see the stones & skills guide

Evidence & update notes

• 22-mission list and order: [MULTI-PLAYER] — Space4Games progress guide (22 missions), consistent with GMTreks’ 23-entry walkthrough (one extra entry likely a split/optional step; treating 22 as the main-story count pending cross-check).
• Mission names quoted as written at source.
• Length: [MULTI-PLAYER] G2A (~20h story), TimeSaver (20–25h), Dot Esports (~30h with optional content), GMTreks (up to 33h all-side-content).
• Point of no return at Mission 22: [SINGLE-SOURCE] Space4Games — flagged for re-verification.
