Onimusha: Way of the Sword — Mysteries & Chance Encounters

The 8 Mysteries of Kyoto with their unlock conditions, the 18 Chance Encounters and the townsfolk rescues — every side activity and its trophy. For physical collectibles see our collectibles & locations guide.

How side content works

Butterflies, notebooks & the Curious Cases menu

Kyoto's side activities open up after the mission “What Lurks in the Shadows.” Mysteries of Kyoto appear as butterfly markers on the map (track them in the Curious Cases menu as Observations); Chance Encounters appear as notebook markers you start by talking to the NPC there.

Nothing is missable. After the credits, pick Continue from the main menu and you're dropped back just before the final mission — free to finish every Mystery, Encounter and rescue. So clear what you can as you go, and mop up the rest at the end.
Mysteries of Kyoto

8 investigative cases

Eight self-contained investigations, split across two regions. Some only unlock after specific story missions, so revisit as you progress:

Kiyomizu-dera Temple · 3

1. The Light of Vengeance — available as soon as the Mysteries unlock.

2. A Wife's Prayer — opens after “Bloodbath on the Bridge”.

3. Something in the Water — opens after “A Tempest at the Temple”.

Eastern Kyoto · 5

4. The Blessed Man — available as soon as the Mysteries unlock.

Chance Encounters

18 side missions

Eighteen bite-sized side missions marked by notebook icons across Kyoto, the temples, the castle and the mountains. Walk up to the marker, speak to the NPC to start it, and complete the short task. They unlock steadily with story progress — there's no wrong order, and none can be permanently lost. Two families make up most of the list: Ace Archer (5 bow-accuracy challenges — great practice toward Deadeye's 100 headshots) and Hidden Treasure (5 dig-site hunts you solve from a clue).

Rescues

Townsfolk & merchants

As you explore you'll find civilians and merchants under attack by Genma. Step in and cut the demons down — rescue 30 townspeople in total for Citizen Savior (you'll pass 30 well before the end just by helping everyone you see), and save a cornered merchant at least once for Selfish Selflessness.

bronze trophyTrophy · Bronze
Citizen Savior — Rescue 30 townspeople from attacking Genma and speak to each afterward — the conversation is what banks the count.
bronze trophyTrophy · Bronze
Selfish Selflessness — Rescue a merchant being attacked by Genma (a special townsfolk rescue). Saving one also opens their shop.
