The timer hits zero and the world boss roars; your fingers hover over the keyboard and you know this fight decides a lot. I’ve stood by the spawn more than once, watching other players claim the drop while my inventory stayed stubbornly empty. If you want that Malevolent Key, you need a plan that actually works.

I’ll keep this blunt: there are two reliable routes—one is a guaranteed burst of reward, the other is steady accumulation while you grind. Pick the one that fits the time you have and the build you’re running.
Defeat Cursed King (Sukuna) at Shibuya Station
The Cursed King is a world boss that respawns on a five-minute clock. Kill him and you receive a Malevolent Key with a 100% drop rate. He’s tagged as an easy-level boss, so a Gryphon sword or any equivalent-tier blade will handle the job if your damage build is competent.
Pro tip: if you don’t want to wait for the spawn, server-hop until you catch the boss alive. I’ve done it dozens of times on Roblox servers; it’s quick and efficient when you need keys fast.
Defeat Curse NPCs at Shinjuku Island
If you prefer steady farming, head to Shinjuku Island and clear the Curse enemies to the left of the portal. They drop Malevolent Keys at a lower rate than Sukuna, but they’re perfect for AFK or semi-AFK loops.
Equip an AoE sword or a strong melee fighting style and clear groups quickly. This is the farming loop most creators on YouTube and Discord recommend when you can’t babysit a world boss spawn.

I want you to shave hours off your grind with a few focused moves. These are the changes that actually move the needle.
- Build for damage first. The faster you kill, the more keys per hour you get. Gryphon-class weapons remain crowd favorites.
- Server-hop Sukuna for instant drops; server-hopping is standard practice on Roblox servers when a boss timer slows you down.
- If you AFK-farm the Curse enemies, boost your Luck stat via titles, clans, Spec Passives, and race bonuses—Luck pulls drops like a magnet.
- Raise your Ascension level, spend Skill Tree nodes in luck-related branches, and equip runes that favor drop rates.
- Join active Sailor Piece Discord servers and follow creators on YouTube or Twitch for spawn tips and group runs; a coordinated push frees you to take bigger fights.
What is the fastest way to get Malevolent Keys in Sailor Piece?
For pure speed, spam the Shinjuku Curse enemies with an AoE build. If you want instant keys and you can handle brief fights, server-hop Sukuna at Shibuya Station—he drops a Malevolent Key every time.
You spot one NPC standing alone amid the chaos. How to Use Malevolent Key in Sailor Piece
Find the Strongest Boss Summoner NPC on Shinjuku Island—he’s a few steps from the portal. Hold E to open the summoning window and you’ll see two options: The Strongest of Today and The Strongest in History.
Use Malevolent Keys to summon The Strongest in History. Normal difficulty costs one key; each higher difficulty adds one more. Defeating this boss nets a chance at Cursed Flesh, a material you need for Ascension to level 7, and other pieces required to get Sukuna V2.
Think of the Malevolent Key as a crowbar that pries open the late-game doors—if you want the rare mats, you’ll need to spend them.
