Sendai Island Location and NPC Overview

Everything starts at Sendai Island, which is the main hub for this update. When you arrive, you’ll notice several important NPCs placed around the island, and each one plays a role in your progression. You’ll find the Yuji seller NPC, Yuji quest NPC, Modulo Yuji seller NPC, and the Modulo quest NPC.

There’s also a boss spawner that becomes important later in the grind. At first, it might feel confusing seeing everything at once, but the key is to follow the process in order. Start with Yuji first, then slowly work your way toward Modulo Yuji.

How to Unlock Base Yuji

Before you even think about Modulo Yuji, you need to unlock the base version. The process is simple and doesn’t take long if you stay consistent.

• Complete the Yuji Quest Line
  The main objective here is defeating 10 cursed spirits. These enemies spawn every 3 minutes on Sendai Island, which makes farming them pretty straightforward. You don’t need to jump between areas or servers—just stay on the island and keep clearing them as they appear. The short spawn timer helps you finish this quest quickly without long downtime.
• Purchase Base Yuji
  Once you complete the quest line, you’ll unlock the ability to buy Yuji. This version is quite basic, only offering two moves. While it may feel underwhelming at first, it’s an important stepping stone because many of the items and requirements for Modulo Yuji come from this progression path.

Modulo Yuji Quest Line (Step-by-Step)

After getting base Yuji, the real grind begins. The Modulo quest line is longer, but still manageable if you follow each step properly.

• Defeat More Cursed Spirits The first part continues the same farming loop. You’ll need to defeat more cursed spirits, which is easy since you’re already familiar with their spawn pattern. This step mainly exists to extend progression and prepare you for harder fights.
• Defeat 50% Sukuna Boss (3 Times) This is your first real challenge. You can spawn the boss using the boss spawner on Sendai Island, so there’s no need to search for it. Since you only need to defeat it three times, this part is relatively quick as long as your damage is decent.
• Defeat Mahoraga (Using Sukuna Shibuya) This step requires a bit of movement. You’ll need to go to Glacier Island and use the teleporter to access the Sukuna Shibuya area. From there, defeat Mahoraga. It sounds complicated, but once you know the route, it becomes routine.
• Defeat 50% Gojo Boss (Using Sukuna Shibuya) Similar to the previous step, you’ll stay in the same area and defeat the Gojo boss at 50% difficulty. This continues the boss-focused part of the quest line and prepares you for the final grind.

How to Get Modulo Yuji (Full Requirements)

Unlocking Modulo Yuji requires more than just finishing quests—you’ll need specific drops and titles.

• Farm Base Yuji Boss Drops To spawn the Modulo Yuji boss, you need several materials: 10 Black Sparks, 10 Curse Essence, 1 Shrine Cursed Technique, and 1 Blood Manipulation Technique. All of these are dropped by the normal Yuji boss, so expect to spend time farming here.
• Spawn and Defeat Modulo Yuji Boss Once you have all the required items, you can spawn the Modulo Yuji boss. This boss drops key items like True Black Sparks and the Prince of Black Flash title, both required to unlock the spec.
• Final Quest Requirement The last step is defeating 10 Modulo Yuji bosses. This is the longest part of the grind, but by this point, you’ll already understand the mechanics and farming loop.

Modulo Yuji Moveset and Mechanics

What makes Modulo Yuji stand out is its unique combat system. Unlike most specs, it offers two different modes.

• Dual Mode System (V Skill)
  Pressing the V move allows you to switch between two modes. This changes how your abilities behave, giving you more flexibility in combat. It’s not just a visual change—it directly affects your damage and combos.
• Dynamic Skill Changes (Z and C Moves)
  Your Z and C skills will change depending on the mode you’re using. This creates a more complex playstyle where you need to think about timing and positioning instead of spamming skills.
• Consistent Finisher (F Move)
  The F move remains mostly the same across modes, acting as a reliable ability that you can use in any situation. This balance between changing and stable skills makes the spec easier to learn while still feeling advanced.

Why Modulo Yuji Is Worth It

Modulo Yuji isn’t just strong—it’s one of the most creative specs added to Rogue Piece so far. The dual-mode system gives it more depth than most abilities in the game, and the damage output is strong enough for both farming and boss fights. The grind might seem long at first, especially with all the boss drops and requirements, but each step feels connected. You’re not just farming randomly—you’re building toward a spec that genuinely changes your gameplay.

Getting Modulo Yuji takes time, but the process is clear once you understand the flow. Start with base Yuji, complete the quest lines, farm the required boss drops, and stay consistent through the final grind. There are no shortcuts here, but the structured progression makes it manageable.

If you’re looking for a spec that stands out and actually feels different to use, Modulo Yuji is easily one of the best choices in Rogue Piece right now. Stick with the grind, and the payoff will be worth it once you unlock its full potential.
