Muzan's Blood
Muzan's Blood is the conversion reward after you collect nine Spider Lilies and deliver Dr. Higoshima. Check that both Muzan Quest counters are complete, find the vial in Inventory and use it. The vial's receipt and the transformation are separate actions.

Complete both objectives for the vial
The two objectives can be completed in either order. If one row is still short, finish it before looking for the blood reward.
| Objective | Completion mark | Next check |
|---|---|---|
| Spider Lilies | 9/9 | Collect the remaining flowers along the water and harbor houses. |
| Deliver Dr. Higoshima | 1/1 | Carry him to the marked destination, not just away from his platform. |
Use Muzan's Blood from Inventory
The Biwa Bell takes you to Muzan's domain; it is not the conversion item. The blood vial is the final item to use.
- After both quest rows complete, open Inventory and locate Muzan's Blood.
- Select the vial and use it.
- Wait for the transformation sequence, then inspect your character route and new Demon progression options.
Prepare the first Demon session
Conversion does not automatically unlock a Blood Demon Art moveset. Start the Art roll and its own training afterward, then inspect the skill tree for move requirements.
Daylight travel also needs preparation. Obtain and equip Black Amigasa before leaving shade for an extended trip, then check the Sun Immunity effect in your character display.
