If you want to play as a Demon in Slayers 2, you need to complete Muzan’s quest before you can access the Demon path. The process requires negative Reputation, finding Muzan at night, collecting Spider Lilies, and delivering them to Dr. Higoshima. Here is the complete guide to Demon progression in Slayers 2.
How to Become a Demon in Slayers 2
To become a Demon in Slayers 2, you need to reach -40 Reputation and then complete Muzan’s quest. Becoming a Demon is much easier than becoming a Slayer, though it still has a few parts you might struggle with. Here is a step-by-step walkthrough on how to become a Demon:
- Lower your Reputation to -40. The easiest way to do this is by killing Civilians in towns at night. You gain -1 Reputation for each Civilian you kill.
- Find Muzan at night. He usually spawns at Hidden Mist, Iceveil, or Mistfall Harbor.
- Talk to Muzan to start his quest.
- Collect 9 Spider Lilies. They spawn both at day and night.
- Find and deliver the Lilies to Dr. Higoshima.
- Complete the quest and receive Muzan’s Blood.
- Drink Muzan’s Blood to become a Demon.

Where to Find Muzan in Slayers 2
Muzan only appears at night, so you won’t find him during the daytime. He can spawn in several locations, including Mistfall Harbor, Iceveil Valley, and Hidden Mist Village. Once you find Muzan, speak to him to start the Demon quest. If he isn’t at one of the locations, you can try switching servers and checking again.
How to Complete Muzan’s Quest
After speaking to Muzan, you need to collect 9 Spider Lilies. These flowers can be found around Bamboo Grove Sanctuary, including areas around the cliffs and water.
Once you have all nine, you need to find Dr. Higoshima and deliver the Spider Lilies to him. Reaching the doctor requires movement abilities such as Wall Climb and Double Jump, so make sure you’ve unlocked them before starting the quest.
After completing the quest, you’ll receive Muzan’s Blood. Open your inventory and drink it to transform your character into a Demon.
How to Survive as a Demon
Becoming a Demon means you need to worry about sunlight. New Demon players can use a head accessory that provides Sun Immunity, such as the Black Amigasa, to avoid taking damage while outside during the day.
Once you’ve transformed, you can start working toward the Demon progression system and eventually unlock Blood Demon Arts.
