Legacy Piece buries the Destructive Moon style behind a questline that trips up a lot of players, mostly because the naming is inconsistent. The character is called Akaza, the boss you farm is called Aaza, and the reward itself is Destructive Moon. Three different names for one unlock chain. This guide cuts through the confusion with a clean step-by-step walkthrough, boss farming advice, and the exact mistakes that stall players before they ever see the finish line. All of this takes place in Roblox, so make sure you're in the right game before following any steps.
What do you need before starting the Akaza questline?
Don't touch the Akaza NPC until you've met every prerequisite. The quest gates on two hard requirements, and walking in unprepared means grinding mid-quest instead of pushing straight through.
The combat requirement matters too. You'll need to kill 100 Demon Slayers in one session and then farm the Aaza boss multiple times. If your build can't handle sustained combat, level up first.

How to unlock Akaza in Legacy Piece
Run these steps in order. The whole questline comes down to one Slayer Mansion visit, a farming session on the Aaza boss, and two NPC conversations.
Step 1: Talk to the Akaza NPC at Slayer Mansion
Head to Slayer Mansion and speak with the Akaza NPC to open the questline. This is the only entry point, so don't skip straight to farming.
Step 2: Confirm your requirements
The NPC will display your current rank and currency. Confirm you have rank B or higher and 3 million currency before accepting. If either is missing, the quest won't progress.
Step 3: Devour seven Man Blood
The first active objective asks you to devour seven Man Blood. Complete this before moving on.
Devour 7 Man Blood to progress
Step 4: Slay 100 Demon Slayers
Grind out 100 Demon Slayer kills in a single session. Spreading this across multiple sessions wastes time, so clear it in one run.
Step 5: Summon the Aaza boss
Find the Boss Summoner NPC and summon the Aaza boss. This is the farming stage of the quest.
Step 6: Farm three Juggling Balls
Kill the Aaza boss and check its drops. You need three Aaza Juggling Balls to progress. Drops are not guaranteed on every kill, so plan for multiple attempts.
Step 7: Find and talk to Kyuki
This is the step most players miss. Open the NPC section, search for Kyuki, track her down in the city, and speak with her. You must do this before the final turn-in registers.
Step 8: Return to the Akaza NPC
Go back to the Akaza NPC at Slayer Mansion and turn in the quest. This awards Destructive Moon, the Akaza-inspired style added to your kit.
How to farm the Aaza boss efficiently
The Aaza boss is where this questline eats most of your time. Treating it as a repeat-farm from the start saves a lot of frustration.
Get your rank B and 3 million currency sorted before you ever start the quest, then clear the 100 Demon Slayers in one uninterrupted session. Once you reach the drop step, re-summon the Aaza boss back to back without taking breaks between kills. The Juggling Balls don't drop on every kill, so keeping a consistent kill pace is the fastest path to three.
After testing multiple farming runs against this boss, the biggest time loss comes from players who pause between summons or switch servers mid-farm. Stay in the same session and keep the summons rolling.
What does Destructive Moon unlock?
Completing the questline and returning to the Akaza NPC rewards Destructive Moon, a full anime-inspired combat style tied to the Akaza character. Once unlocked, you can take it directly into combat and start learning its moveset. The style is the entire payoff for the questline grind.
What mistakes block the Akaza unlock?
Two mistakes inside the quest stall players most often.
The first is farming the Aaza boss before the quest is at the correct stage. Juggling Balls won't register if you haven't completed the earlier objectives, so follow the steps in order.
The second is skipping Kyuki. Players who collect all three Juggling Balls and go straight back to the Akaza NPC find the turn-in does nothing. You must locate Kyuki in the NPC search, travel to her in the city, and speak with her first. There's no shortcut here.
A third issue affects players who followed guides for other games. Weak Legacy 2, Starfall Legacy, and Slayer's Legacy all have separate Akaza systems with completely different requirements. If a guide mentions Akaza V1/V2 or Demon Art unlocks, it was written for a different game. The Legacy Piece questline only involves Slayer Mansion, the Aaza boss, and Kyuki.
