Musashi's adventure in a corrupted Kyoto takes him through numerous battles, supernatural encounters, and important story moments. With 22 main missions and a large amount of optional content, it can be useful to have a complete list of objectives in one place.
This guide covers every main mission in Onimusha: Way of the Sword, as well as the game's side quests and additional activities. The missions are presented in their progression order, making the list useful both for players focused on the story and those working toward 100% completion.

There are 22 main missions in Onimusha: Way of the Sword. Together, they form the game's primary storyline and take Musashi across several major areas of Kyoto.
The campaign starts with the events at Rendaino and gradually introduces more dangerous locations and challenges. Since the main story follows a mostly linear progression, players generally won't have to worry about choosing the wrong mission order.
The complete main mission list is:
The final mission is The Clash at Rendaino. Starting this quest marks the game's point of no return, so it is best to deal with any unfinished optional activities beforehand.
Players pursuing a completionist run should use this mission as their final checkpoint. Finish remaining side quests, mysteries, and collectibles before proceeding with the ending.




The main storyline is not the only way to spend time in Onimusha: Way of the Sword. Kyoto contains numerous optional activities that allow Musashi to meet additional characters, investigate unusual situations, and earn rewards.
Among the available content are Mysteries of Kyoto, Chance Encounters, and other optional missions. New activities can appear as the story advances, which makes it worthwhile to check the map from time to time.
Optional quests also provide additional context for Kyoto and its inhabitants. Musashi can encounter people with their own problems and investigate unusual incidents rather than simply following the main storyline.
The side quest list includes:

A straightforward run through the main story should take roughly 20 hours. Players who spend more time exploring and completing optional objectives can expect an average playthrough of approximately 25 hours.
Those looking to complete everything will need considerably more time. Optional missions, collectibles, and post-game activities can all extend the overall playtime.
It is also worth returning to areas that you have already visited. Additional objectives can become available later in the story, giving you new reasons to explore previously completed locations. Hidden Lion Dogs can also be found during these return visits.
The Platinum trophy requires an even greater time investment. Some rewards and unlockables are tied to Carnage difficulty, so players aiming for full completion should be prepared for another challenge.
While the main campaign can be completed relatively quickly, the optional content provides plenty of reasons to continue exploring Kyoto.
What is the final mission in Onimusha: Way of the Sword?
The final major story mission is The Clash at Rendaino. It also serves as the point of no return, so completing unfinished optional content before starting it is recommended.
Is it possible to complete side missions before finishing the main story?
Yes. Most players interested in a completionist run should finish the available optional content before beginning The Clash at Rendaino.
Can you return to previously visited locations?
Yes. Earlier areas can be revisited later in the game. Doing so can reveal additional objectives and locations, including hidden Lion Dogs.
As a Reminder, Sony dropped Physint, but Hideo Kojima’s game wasn’t canceled and will now be published by Xbox.
