Current confirmed checklist
The official PlayStation demo page names Sasaki Ganryu. The cited Xbox Store description names Sasaki Ganryu and Daidara, and the latest PlayStation preview describes the updated demo adding a large Daidara encounter.
For the current research snapshot, the defensible checklist is therefore:
- Sasaki Ganryu
- Daidara
Important boundary
These are confirmed demo encounters, not a complete roster for the full game. This article does not infer unrevealed bosses from trailers, earlier Onimusha games, community posts, or demo footage.
A boss present in a demo is not evidence that every full-game boss has been announced. Conversely, a boss absent from this short list is not proof that it will not be in the game.
Why there is no strategy table
The approved material identifies the encounters but does not support reproducible, version-stable strategy claims, phase tables, health values, or guaranteed rewards. This page will remain a factual checklist until tested post-launch evidence is available.
