Rogue Piece Modulo Yuji Guide – How to Get, Quest

If you’ve been grinding Rogue Piece lately, you’ve probably already heard the hype around Modulo Yuji. And honestly, it’s not overblown. This update actually adds one of the most interesting specs the game has seen in a while. It’s not just strong, it’s fun to use, which is rare.

I spent some time going through everything step by step, and I’ll break it down for you in a way that actually makes sense when you’re playing, not just reading.

Rogue Piece Modulo Yuji Guide – How to Get, Quest

Everything begins at Sendai Island. This is basically your main hub for the entire Yuji progression.

Here’s what you’ll find there:

  • Yuji Seller NPC
  • Yuji Quest NPC
  • Modulo Yuji Seller NPC
  • Modulo Quest NPC
  • Boss Spawner

It might look confusing at first, but once you understand the flow, it’s very straightforward.

Step 1: Unlocking Base Yuji

Before anything else, you need to unlock base Yuji.

Quest Requirement:

  • Defeat 10 Cursed Spirits

These enemies:

  • Spawn every 3 minutes
  • Are easy to farm solo
  • Don’t require any special setup

Honestly, this is just a warm-up quest. You’ll finish it quickly without even thinking too much.

Once done, you can buy Yuji from the NPC.

Base Yuji – Is It Good?

Let’s be real here.

Base Yuji is:

  • Very basic
  • Only has 2 moves
  • Not meant for long-term use

It’s more like a stepping stone. You’re not here for base Yuji, you’re here for Modulo Yuji.

Step 2: Modulo Yuji Questline

Now things get interesting.

To unlock Modulo Yuji, you’ll go through a multi-step questline. It sounds long, but none of it is actually difficult.

Quest 1: Kill More Cursed Spirits

Same as before, just grind a few more.

Quest 2: Defeat 50% Sukuna (3 Times)

  • Use the Boss Spawner on Sendai Island
  • Spawn 50% Sukuna
  • Defeat him 3 times

Tip:
This boss is manageable solo, but faster with a group.

Quest 3: Defeat Mahoraga (Using Sukuna Shibuya)

This is where players get confused.

What you need to do:

  • Go to Glacier Island
  • Enter the teleporter
  • Use Sukuna Shibuya
  • Defeat Mahoraga

Important:
You must use Sukuna Shibuya here or it won’t count.

Quest 4: Defeat 50% Gojo (Using Sukuna Shibuya)

Same concept again:

  • Use Sukuna Shibuya
  • Fight 50% Gojo
  • Complete the requirement

Step 3: Unlocking Modulo Yuji

After finishing the questline, you still don’t instantly get Modulo Yuji.

You need specific items:

Required:

  • True Black Sparks
  • Prince of Black Flash Title

These come from the Modulo Yuji Boss.

How to Spawn Modulo Yuji Boss

To summon the boss, you’ll need:

  • 10 Black Sparks
  • 10 Cursed Essence
  • 1 Shrine Cursed Technique
  • 1 Blood Manipulation Technique

And here’s the catch:

All of these drop from the Base Yuji Boss.

So yeah, you’ll be farming that boss quite a bit.

Farming Loop (Important)

This is your actual grind cycle:

  1. Farm Base Yuji Boss
  2. Collect required materials
  3. Spawn Modulo Yuji Boss
  4. Get drops
  5. Repeat

No shortcuts here, just efficient farming.

Final Requirement – Ultimate Quest

Even after unlocking Modulo Yuji:

  • You need to defeat 10 Modulo Yuji Bosses

This is basically the final test before you fully complete the progression.

This update feels like a proper upgrade to Rogue Piece instead of just another content drop. The progression is clear, the grind is fair, and the end result is actually worth the effort.

If you’re planning to main a spec that won’t feel boring after a few fights, Modulo Yuji is a solid pick.
