How to Become a Demon - Project Slayers 2 Wiki
The fastest reputation route to Muzan, the demon conversion process, and what changes once you turn.
Overview
Becoming a demon in Project Slayers 2 is a reputation route rather than a menu choice, and picking the demon path at character creation only sets your direction. You still need negative reputation, a night meeting with Muzan, his quest materials and finally his blood, which permanently swaps your kit to Blood Demon Arts.
Fast Demon Route on Video
The run below starts from a fresh character and shows the reputation grind from spawn to Muzan, which is the part most players get wrong. Follow it once before you commit, then cross-check the numbers against the quests guide so you do not waste a night cycle on the wrong objective.
The Demon Conversion Route
The route has a fixed order and the game will not let you skip ahead. Reputation comes first, movement skills come second, and only then does Muzan become reachable and willing to talk. Budget one focused session for the reputation grind and another for the quest itself, because the meeting only happens at night and daylight resets your window.
Preparation is what makes this fast. Carry consumables for the trip, unlock Double Jump and Wall Climb before you leave, and know the Spider Lily spots before the sun sets so the collection phase does not eat your whole session. The locations hub covers the areas you will cross.
Drop your reputation to -40
Lower your reputation to -40 or below before Muzan will deal with you at all.
Unlock Double Jump and Wall Climb
Both movement skills are needed to reach the meeting point, so unlock them before you attempt the run.
Wait for night
Muzan only appears during the night cycle, so plan your travel so you arrive after dark with time to spare.
Collect nine Spider Lilies
Gather all nine flowers the quest asks for and keep them on you rather than banking them at a storage NPC.
Deliver the doctor
Escort or deliver Dr. Higoshima as the quest instructs, which is the step most players fail by rushing ahead.
Drink Muzan's Blood
Finish the conversation and drink the blood to convert, which replaces your entire kit with demon abilities.
Demon Requirements at a Glance
The table collects every gate on the conversion in one place. Reputation, movement, timing and materials all have to line up at once, and a single missing piece sends you back to the start of the night cycle. Check it before you commit to the run, because leveling during the day and converting at night is the most efficient split.
Spider Lilies are the step that slows most players down. Nine is a real collection task rather than a single pickup, so scout the route in daylight first and return at night knowing exactly where each flower sits. Treat the doctor's delivery the same way and the whole chain becomes routine.
| Requirement | Value | Why it matters |
|---|---|---|
| Reputation | Minus 40 or lower | Muzan ignores you until it is negative enough |
| Movement skills | Double Jump and Wall Climb | Both are needed to reach the meeting point |
| Timing | Night cycle only | Muzan does not appear in daylight |
| Quest materials | Nine Spider Lilies | Collected before the doctor is delivered |
| Final step | Drink Muzan's Blood | Converts you and replaces your whole kit |
What Changes After You Turn
Conversion is not a buff, it is a replacement. Your breathing style and slayer skills are gone, replaced by Blood Demon Arts and a separate Demon Progress system that grants abilities and stat bonuses as you develop it. Nine Blood Demon Arts exist across seven demon weapons, and maxed Demon Progress pushes late-game demon damage higher.
The trade-off is sunlight. After turning, daylight becomes lethal, so the rhythm of the game shifts toward night play and shaded routes. The early demon perks include a measure of sun immunity while you are still developing, but the weakness is real and shapes where and when you farm, which is why map knowledge matters so much on this path.
Demon weapons also change your options. Sickles, claws and umbrellas appear in the demon kit, and late demon builds scale through Demon Progress rather than the slayer skill tree. If you are still deciding, the breathing styles overview shows what you give up on the slayer side.
Why Players Choose the Demon Path
The demon path suits players who want a different late-game curve rather than a stronger early one. Slayers get their full combat style sooner, while demons trade that comfort for scaling that keeps climbing through Demon Progress and demon-only weapons. Read the end game guide before you commit either way.
Blood Demon Arts
Nine arts across seven demon weapons replace breathing entirely, giving the path its own identity.
Demon Progress
A separate progression track grants abilities and bonuses, including extra damage at maximum.
Night Play
Sunlight becomes lethal, so demon farming and boss attempts naturally move into the night cycle.
Wisteria Warning
Wisteria and nichirin blades counter demons, so expect slayer players to build around those tools.
Before You Turn
Finish this list before you drink the blood, because conversion replaces your kit and there is no partial version of the change. Spend your remaining slayer resources first, bank the Wen you want to keep and make peace with losing the breathing style you leveled. The mastery and Wen guide explains what carries value afterward.
If you are close to a milestone, finish it first. Final Selection, your first forged katana and the level brackets around them are all easier to complete as a slayer, and converting early can leave you without the code rewards and materials you would rather have banked.
- Reputation already at minus 40 before you travel
- Double Jump and Wall Climb unlocked and tested
- Nine Spider Lilies scouted in advance
- Slayer milestone rewards claimed before conversion
Frequently Asked Questions
What reputation do I need to become a demon?
You need minus 40 reputation or lower. Muzan will not deal with you until your reputation is negative enough, so grind it first.
Can I become a demon at level 1?
The route is doable early because it depends on reputation and movement skills, but you still need Double Jump and Wall Climb unlocked before you travel.
Where do I find Muzan?
Muzan appears at night. Plan your travel so you arrive after dark, because the meeting does not happen during the day cycle.
How many Spider Lilies do I need?
Nine. The quest asks you to collect nine Spider Lilies and deliver the doctor before the blood is offered, so scout the route first.
What happens to my breathing style?
It is replaced. Conversion swaps your entire kit to Blood Demon Arts and a separate Demon Progress track, so slayer skills no longer apply.
Is sunlight really lethal to demons?
Yes. After conversion sunlight becomes lethal, and the early demon perks only soften that weakness while you are still developing the path.
Can I go back to being a slayer?
Treat the choice as permanent for your character. Nothing carries over from the original game either, so plan your decision rather than rushing it.
