Becoming a Demon in Project Slayers 2 runs on a completely different track than the Slayer path. Instead of earning a katana and passing Final Selection, you drop your reputation into the negatives, hunt down Muzan at night, finish his blood-gathering quest, and drink the vial he hands you. From there your strength comes from souls, Blood Demon Arts, and a separate weapon pool rather than breathing styles.
Quick answer: At night, go to Muzan in Mistfall Harbor once your reputation is -40; gather 9 Spider Lilies, bring Dr. Higoshima to safety, and use Muzan’s Blood in your inventory to become a Demon.
Set up your character before you transform
Every new character slot begins Human, and remains that way until you consume the blood. You can make a Demon in another slot without erasing a Slayer you already have by purchasing an extra slot in the shop. First, roll your clan and prepare a few basics: a level 1 Demon without a hat will burn in daylight, and the quest chain sends you across the map.
Roll your clan from the customization menu. Kamado is the strongest pick because it grants Demons immunity to sunlight along with stat boosts, and Douma and Himejima are the top alternatives from the Mythic tier. Supreme clans sit at a 0.1% roll rate and Mythic at 0.9%, so redeem the code SPINS50 for extra spins, plus ARTRESET and BREATHRESET if you need resets.
Aim for level 20 to 40 before transforming, since the Slayer NPCs that ambush you during Muzan’s quest can otherwise kill you. Also grab these early:
- Complete Recover the Lost Pages by finding its five scattered pages, and Kona at Windy Peak rewards you with the Book of Guidance.
- Get Double Jump, Wall Climb, and Core Detachment through the skill tree; the doctor rescue requires vertical movement.
- Complete MoldySugar’s delivery task at Windy Peak to unlock the hat shop.
- Around 10,000 Wen saved for the Black Amigasa sun hat.
For quick access to movement skills, reach level 5 by finishing the brief delivery and fetch tasks around the starter village, then invest your points in traversal. The Book of Guidance remains pinned on your map screen and highlights recommended quest NPCs. That guidance is useful because the Demon quest chain sends you back and forth between regions.
Reach -40 reputation the fast way
Muzan will only speak with you once reputation reaches -40 or lower. Civilians around the starter village can be killed to lower it, but each one changes the counter by just -1; reaching the target this way means killing 40.
Slayers are far quicker. Patrols near the Butterfly Estate hand out about -9 reputation per kill, which puts you at the threshold after roughly five kills. Bosses like Giyu also qualify, and the Kanoe Demon Slayers in Iceveil Valley are a solid alternative because they feed you useful EXP while you grind the counter down.
The same negative score later grants access to Muzan’s Lair, so once you commit to the Demon route there is no reason to pull your reputation back up.
Level 1 to 26 before the transformation quest
The pre-Demon grind mirrors the Slayer opening. Start with the village quests that send you after bandit spies and civilians, then move to the two combat loops that carry you to level 26.
Repeat Krue’s bandit quest up to level 7, then take his Mini Boss Zuko quest and farm Zuko until level 10. Zuko can drop the Cutlass weapon as an early upgrade.
Pick up Lucy’s and Tom’s bear quests. Cycle regular Bear Cubs and the Mother Bear boss, using short M1 combos and backing off when you get interrupted, until you hit level 26.
Find Muzan and complete his transformation quest
Muzan appears at night, traveling among village zones. You are most likely to spot him in Mistfall Harbor, near the beginner area; Hidden Mist Village and Iceveil Valley are also possible spawn locations. Try switching servers until you find one at night, or wait through a complete day cycle in your current server—sometimes that takes less time.
Success is confirmed when you can equip the Demon title and access both the Demon Progress menu and Muzan’s Lair. Seeing the title alongside the progression bar means the transformation worked. You can return to the editor to change your Demon’s hair, skin, eyes, and clothing; ranking up also unlocks some appearance options exclusive to Demons.
Survive daylight with a clan or a sun hat
Demons burn away and die if they stand in sunlight unprotected, which blocks daytime questing and some Blood Demon Art training objectives that take place outdoors. There are three ways to handle it.
The Kamado clan gives complete immunity to sunlight, so that clan removes the issue. Otherwise, after completing MoldySugar’s delivery, find Elara in Mistfall Harbor and purchase the Black Amigasa for 10,000 Wen. Her stock cycles about once an hour; if the hat isn’t available, check back later. Raid captains may drop the Bamboo Sandogasa as well, and it provides the same immunity.
The Black Amigasa is a handy stand-in for now. It keeps sunlight off you but provides no stat bonuses; stronger hats with useful effects appear later.
Roll a Blood Demon Art and clear Core Training
At low reputation, you can revisit Muzan’s Lair to roll for Blood Demon Arts. You start with five spins, and each roll costs three, enough for your first attempt but not a second. Robux aren’t necessary: bosses and chests, luck chests included, may drop BDA orbs that work in place of paid spins.
Selecting an orb assigns a Core Training quest at random, with tasks determined by the art. For Cryokinesis, meditate at Butterfly Estate, complete the Boulder Split timing game at White Terror Lair, gather five underwater rock nodes at Bamboo Grove, then defeat five Mizunotos. Shockwave’s tasks are push-ups in the Butterfly Estate gym, barbell squats outside the estate, a boulder-pushing course, the Boulder Split game, and two Mizunotos. Complete the full list to unlock the art.
Dying during a Blood Demon Art quest can erase its progress, so stay away from dangerous fights until the objective is done.
After unlocking the art, buy its first ability in the skill tree. Mastery is needed for later abilities, and you build it by using the art’s techniques in combat. Weapon needs depend on the art: some require no weapon, while others do. Blood Manipulation, for instance, requires a sickle that drops only from a level 52 boss, making it a tough option for a new Demon.
Blood Demon Arts ranked for PvE
| Tier | Blood Demon Art | Origin |
|---|---|---|
| S | Blood Sickles | Gyutaro |
| S | Cryokinesis | Douma |
| A | Speed Augmentation | Slasher |
| A | Dream Manipulation | Enmu |
| A | Destructive Death | Akaza |
| B | Combustible Blood | Nezuko |
| B | Arrow | Yahaba |
| C | Flesh Manipulation | Daki |
| D | Temari | Susamaru |
These rankings are built around PvE, the game’s main activity right now. When you judge a roll, weigh how reliably its main damage move lands over its theoretical ceiling. An art that connects consistently clears content faster than a higher-damage option that demands a perfect setup, and rerolling just because an art is popular usually spends more resources than it saves.
Demon progression and soul farming
Your Demon progression is separate from character level and provides a large share of your passive strength. Slayers raise a similar stat by buying gourds; Demons improve theirs by killing human NPCs and collecting the souls they leave behind. To check the bar, press M, select Player Info, and open Progression. The maximum is Level 4, granting +100 Max Health, a Max Health factor, an Evil Art Damage factor, and +2 additional damage.
| Soul type | Dropped by | Progress value |
|---|---|---|
| Weak Soul | Low-level NPCs and players | +5 |
| Strong Soul | NPC bosses and trainees | +10 |
| Brave Soul | Hashira, world bosses, level 125+ players | +25 |
Reaching Level 4 takes 10,000 total progress points. A quick method is having a high-level friend reset or get farmed near a respawn point so you stack Brave Souls fast. Two things waste effort, so avoid them: Demon kills award no souls, so only target human NPCs, and save any 2x Soul boosts for boss sessions rather than ordinary mobs.
Demon leveling route to 125
Transformation puts you on a quest route separate from the Slayer path. The quest givers below cover different level ranges. If you need to locate the next one, open the map using the Book of Guidance and switch on Recommended Quest to highlight the correct NPC.
| Levels | Quest giver | Location | Targets |
|---|---|---|---|
| 1–10 | Krue | Starter area | Bandits |
| 10–26 | Tom | Starter area | Bear cubs, Mother Bear |
| 26–40 | Chaka | Starter area | Kaiden subordinates |
| 40–62 | Wagwan | Bamboo Grove cave | Hoyozu quests |
| 62–75 | Shady Individual Rooyi | Mistfall Harbor | Mizunotos |
| 75–90 | Demon Mokuro | Behind Butterfly Estate waterfall | Assorted hunts |
| 90–105 | Demon Delroy | Iceveil Valley | Kanoe slayers |
| 105–125 | Demon Slayer Mitsu | Iceveil Valley | Frost and Blaze demons |
Between quest groups, check Muzan’s task menu. Nearby trainee Slayer targets give fast EXP while pushing your reputation even lower. Finish the starter-area quests at least once with any race too, since several unlock shrines and other progression systems.
Once you pass level 100, standard quests give EXP very slowly; one repeatable errand is a better way to finish leveling. Travel directly to the Frost Veil Shrine in Iceveil Valley and take Iceveil Guard Shiro’s restocking task. Purchase the requested health elixirs in Mistfall Harbor, then deliver them. At this level, each hand-in outpaces most combat quests for EXP.
At the level 125 cap, use the Biwa Bell to take Muzan’s bounty missions, which send you after bosses such as Rengoku, Shinobu, and Akaza. With levels capped, these missions reward mastery instead; repeating them is the fastest way to complete your weapon and Blood Demon Art skill trees.
Demon weapons and the bosses that drop them
Demons wield a different set of weapons from breathing-style katanas. Their usual options are Sickles, Claws, and the Spear. The Bladed Wagasa umbrella is notable for its strong combat stats and innate sun immunity. Kaiden drops Claws, making them an easy early upgrade to pick up while completing Chaka’s quests.
Hoyuzo: Sickles and Sickles V2
Hoyuzo the Sickle Reaper lives in the waterfall cave at Iceveil Valley, with drops starting at about level 52. This is the boss you need if you rolled Blood Manipulation, since the art is otherwise unusable. Repeat clears supply the Sickles V2 upgrade and refinement materials, and Damascus Sickles sit around a 7% drop rate, so expect several attempts.
Fujiko: Bladed Wagasa
You can find Fujiko around the Butterfly Estate and Final Selection Plains. Defeating her awards the Bladed Wagasa umbrella along with the Shade Breaker move. Its built-in sunlight protection lets you replace the Black Amigasa and use your hat slot for an item with useful stats.
Ultimate move bosses by Blood Demon Art
| Boss | Where | Reward |
|---|---|---|
| Hoyuzo | Bamboo Grove cave | Sickles, V2 materials |
| Yahari | Below Hoyuzo, night only | Arrow ultimate |
| Sumari | Torii gate bridge, night | Temari ultimate |
| Reaper | Behind Sumari | Reaper’s Scythe, Sonido Surge |
| Dabi | Cave near the gate | Obi Manipulation |
| Gyutai | Cave near the gate | Blood Manipulation |
| Domae | Iceveil Valley houses | Ice Demon Art, War Fans, outfit set |
| Akazo | Past the Wind Trainees, Iceveil Valley | Shockwave ultimate |
| Nezura | Final Selection Plains | Blood Rupture ultimate |
Several of these spawn only at night, Domae and Yahari included, so plan around the day cycle instead of fast-travelling in blind. Domae in particular is a long fight with heavy crowd control and multiple drop tables; the Black Dragon Armour, the Legendary War Fans, Domae’s Top and Bottom, and the Black Lotus Crown all come from repeat kills.
Ouigahara Dungeon, V2 weapons, and the endgame loop
V2 weapons are crafted in the Ouigahara Dungeon, but you have to unlock access first. Find Blacksmith Togane in Hidden Mist Village and finish his questline, which adds the standard dungeon to your main menu. Inside the village, Refiner Hagane upgrades weapons and fighting styles up to +7 using Refinement Ores and Yen, and the Duelist set is the best match for endgame Demon armor.
Dungeons are an efficient source of XP and mastery; prioritize the Horde, Blood Moon, Ascension, Boss Hunt, and Berserker card picks. After reaching level 125, leave dungeon runs for Muzan’s boss hunts, which offer endgame items such as Nightfall and First Light gear.
Keep the endgame loop focused: gather souls until Demon progression reaches Level 4, take Muzan’s bounties repeatedly for mastery, and clear Hoyuzo alongside the Ouigahara Dungeon until your weapon is V2. A completed Demon has all three progression lines maxed together, showing that the build is fully developed.
