Muzan's location, the demon route that leads to him, and the rewards tied to that storyline.

Overview

Muzan is less a standard boss and more the gate that turns a human character into a demon. Reaching him takes three separate requirements, and the transformation that follows rewrites your entire kit, so this is the single most consequential NPC interaction in the game for anyone leaning toward the demon path.

The community routes are consistent on the shape of the quest even where the small numbers drift. Drop your reputation low enough, catch him after dark, finish his two objectives, then drink the blood he offers. Everything after that is demon progression rather than a normal boss loop.

Reputation requirement:-40 or lower
Spawn window:Night only
Quest items:9 Spider Lilies
Escort target:Dr. Higoshima
Domain entry:Biwa Bell
Reward:Muzan's Blood (demon transformation)

Muzan and the Demon Path

Muzan is shown off here as the centre of the demon storyline rather than as a health bar to empty. The footage is useful because it makes the two halves of the quest obvious: the reputation grind that earns the invitation, and the Spider Lily hunt that follows it. Pair it with the demon conversion walkthrough.

The Demon Transformation Route

The order below is the one the published guides agree on. The first step is the slowest because reputation drops one point at a time, and dialogue triggers arrive in ten-point increments, so plan for a deliberate grind rather than a lucky encounter. Sprinting the last stretch is what wastes an in-game night.

Do not start the hunt on an empty inventory. The Spider Lily search spans the map, the doctor escort adds travel, and the whole chain is easier when you already carry the Wen and materials the follow-up content expects. Bank a few thousand before nightfall.

1

Drop to -40 reputation

Defeat unstarred civilians or Slayer NPCs; each defeat removes one point of reputation.

2

Wait for night

Muzan only appears after dark, and reports place him in villages such as Mistfall and Iceveil.

3

Accept his quest

Talk to Muzan once the invitation triggers and the Spider Lily objective activates.

4

Collect nine Spider Lilies

The glowing blue flowers spawn at night, so a fixed farming loop beats wandering.

5

Deliver Dr. Higoshima

Find the doctor and bring him to Muzan to close the second objective.

6

Drink Muzan's Blood

The transformation completes on drinking, unlocking arts and demon progression.

Reputation dialogue triggers arrive in ten-point steps, so reaching -40 is a planned grind rather than a single lucky kill.

Requirements and Preparation

Everything below is worth arranging before you start the hunt, because a failed run costs a full in-game night. The reputation figure is the one number every current guide agrees on, while the optional preparation items simply make the transformation less painful for a fresh demon with no Wen reserves.

Choose the demon path deliberately: the transformation swaps your whole kit and makes sunlight lethal, and nothing carries back to the Slayer side.

What Changes After the Transformation

Drinking Muzan's Blood is not a cosmetic swap. It unlocks Blood Demon Arts, a separate demon progression track, passive buffs and access to demon-specific bosses, which is why the route is treated as a fork rather than an upgrade. The Blood Demon Arts list is where most players go next.

The trade-off is immediate. Sunlight becomes lethal, so daytime travel turns into a survival problem until you build around it, and Wisteria is the other obvious counter. Community guides recommend transforming between level 20 and 40 so your first nights are survivable.

A demon-specific boss list opens up alongside the arts, including Enmu in Dreamfall Hollow and the Akaza encounter on the Windy Peak cliffs. Neither is reachable as a normal Slayer run. Plan that loop once your first art is levelled, and check the boss index for the spawn regions.

Preparing for the Hunt

A little setup turns a frustrating night into a short errand. The four points below come straight from the published route guides, and together they cover the movement, money and daylight problems that catch first-time demons immediately after the transformation. Check the boss index for what opens up afterwards.

Movement first

Double Jump and Wall Climb make the Spider Lily loop far less punishing.

Plan for night

Flowers and Muzan both key off the night cycle, so stack objectives in one window.

Carry Wen

A modest reserve covers travel and the first purchases after transforming.

Sunlight answer

Arrange shade routes or wisteria counterplay before your first demon day.

Stack the Spider Lily loop and the doctor escort into a single night where possible; splitting them doubles the waiting time.

Demon Route Checklist

This checklist keeps the whole fork in one place. It is written for a player who has already finished the early quest chains and wants to convert without wasting a night, and it deliberately avoids the numbers that community posts disagree on. For the wider map context, see the locations guide.

Once the transformation lands, the priority shifts from survival to build. Skill points, mastery and art choice all matter more than raw level from that point forward, because maxing character level does not finish your moveset. Pick one art and push it rather than spreading points thin.

FAQ

Frequently Asked Questions

Where do I find Muzan in Project Slayers 2?

He spawns at night rather than at a fixed daytime post. Reports place him in villages such as Mistfall and Iceveil, so search after dark once your invitation triggers.

What reputation do I need for Muzan?

You need -40 or lower. Each unstarred civilian or Slayer NPC you defeat removes one reputation, and dialogue triggers arrive in ten-point increments.

How many Spider Lilies do I need?

Nine. They are glowing blue flowers that appear at night, and collecting them is one of the two objectives in Muzan's quest.

What happens when I drink Muzan's Blood?

You become a demon. That unlocks Blood Demon Arts, demon progression, passive buffs and demon-specific bosses, but makes sunlight lethal.

Can I go back to being a Slayer?

The transformation is a commitment. It swaps your entire kit, and nothing carries back to the Slayer path, so treat it as a permanent fork.

What level should I be before transforming?

Community guides suggest somewhere between level 20 and 40 so you can survive the Slayers who spawn during the quest and handle your first demon nights.

Do I need the Biwa Bell?

It is the item used to enter Muzan's domain once you have found him, so have it ready before the night begins.

Is Muzan a repeatable boss fight?

No. He is the demon storyline gate rather than a farming target, so there is no drop table to farm after the transformation is complete.
