Slayers 2: How to Become a Demon Fast (2026 Guide)

Becoming a demon is one of the biggest power spikes in Project Slayers 2, and it unlocks the entire Blood Demon Art system that breathing-style players can never touch. If you have been searching for a clear answer on how to become a demon in Slayers 2, this guide walks you through every step — from dropping your reputation to surviving your first sunrise. The process is not complicated, but it has a few hidden requirements that trip up new players, including a level gate and a random 25% failure chance on the final turn-in.

Below you will find the exact quest route, the fastest way to farm Blue Spider Lilies, tips for the doctor escort section, and how to spin for your first Blood Demon Art without wasting your free rolls.

How to Become a Demon in Project Slayers 2: Quick Overview

Before you start, know what you are signing up for. The demon transformation permanently changes your spawn point, locks you out of Swords and Breathing styles, and makes sunlight actively lethal. In exchange, you get access to Blood Demon Arts, Scythes, War Fans, and Claws.

Here is the full requirement checklist:

The level requirement is the hard gate. According to the Project Slayers Wiki, you must be at least Level 15 before Muzan will hand over the quest at all. If you are below that, grind NPCs until you hit the threshold — there is no workaround.

Why You Need Negative Reputation

Community guides, including a popular walkthrough from a Project Slayers 2 YouTuber, report that Muzan will not interact with you properly unless your reputation is negative. The fastest way to tank it is to kill five friendly NPCs near the starting area.

From spawn, head east until you hit the big wall, then turn right. Each NPC you defeat there costs you -9 reputation, so five kills puts you at roughly -45. A simple punch, back up, dash in, punch again loop works even at low level.

Once your reputation is negative, head west over the red bridge toward the town where Muzan is known to spawn.

Finding Muzan at Night

Muzan only appears at night, and he spawns in a rotating set of locations rather than a fixed spot. Community trackers have documented around 12 possible spawn points across the map.

A few practical notes from player experience:

• Wait in town until the in-game clock hits night. If it is already dark, start searching immediately.
• The most commonly reported spawn is walking near the town gate.
• If you cannot find him after a full lap, server hop and check again — this is faster than waiting for another night cycle.
• When you talk to him, he hands you a Bell. Equip it and use it to formally start the quest line.

The quest he gives you asks for 5 Blue Spider Lilies and the delivery of Doctor Higoshima. Note that the wiki confirms you only need to bring the doctor back — the lilies are consumed on pickup, so do not worry about carrying them to the turn-in.

Fastest Blue Spider Lily Farming Route

This is the part that eats the most time, so here is an efficient loop based on the community route. Set your spawn crystal at the middle of the lake first, because you will be resetting and rerunning this path repeatedly.

Run the loop, then reset and repeat until you have all five. Spawns are not guaranteed at every point, which is why the route covers multiple potential nodes instead of one.

Mountain Climbing Trick

To reach the ledge spawns without double jump or climb unlocked, use the shift-lock backwards walk method. Enable shift lock, face away from the slope, and walk backward up the incline. You will not slide off, and you can reach spots that normally require movement upgrades.

Escorting Doctor Higoshima Safely

This is the section where most low-level players die. Once you pick up the doctor near the caution sign on the map, slayers will chase you the entire way to the waypoint.

Key survival tips:

• Put a few points into health before starting if you are underleveled.
• Do not fight back. Fighting slows you down and gets you surrounded.
• Keep dodging and sprinting toward the waypoint marker.
• Head across the log bridge and follow the mountain path — the route is designed to be runnable without double jump.

When you deliver the doctor, you receive Muzan's Blood. Using it triggers the 75/25 roll.

What Happens If You Fail the Roll

If Muzan says "You have failed me," you stay human and must redo the entire quest — lilies, doctor, everything. There is no partial credit and no way to bribe your way past it. Budget for the possibility of running it twice.

What Changes After You Become a Demon

Your default spawn moves from Kiribating Village to Zapiwara Cave, and your entire combat toolkit shifts.

Sunlight damage is the biggest adjustment. You take 21 HP every second in direct sun, and dying to it makes you explode instantly rather than ragdoll. Ways to mitigate it:

• Stand in shadows (note: on low graphics settings, shadows may not render)
• Wear the Straw Hat
• Be in the Kamado clan

Going underwater does not protect you, and Rengoku's burn resistance does not apply either. Plan your daytime activities around indoor quests or fast travel.

Soul Farming for Levels

Demons level differently. Instead of normal XP, you consume souls:

• 5 souls per Human or Slayer kill
• 1 soul per civilian NPC (Butterfly Mansion staff)

Every level has a soul requirement, so expect to spend real time hunting players or farming NPCs between quests.

Getting Your First Blood Demon Art

Once you are a demon, use your Bell to teleport to Muzan's area inside Zapiwara Cave. There you will find the Demon Art Spin NPC.

You start with 5 free rerolls, which is only enough for one orb spin. There is a real chance you walk away with nothing, so do not expect a god-tier art on day one.

When you land an art you want, hold it out and consume it, then complete the follow-up quest to unlock it permanently. Mastery is tracked per art — if you reroll from Arrow mastery 40 to Reaper, your Arrow progress is saved if you ever swap back.

One more thing worth checking: some Blood Demon Arts previously required specific weapons equipped to roll or use. Community reports say updates may have relaxed this, so verify the current requirement for your target art before committing spins.

Pros and Cons of Going Demon

If you mainly play at night or with a group, the downsides shrink considerably. If you solo during the day, grab the Straw Hat first.
