How to Get Moon Slayer in Sailor Piece

In the Roblox game Sailor Piece, players can unlock a variety of powerful abilities and fighting styles inspired by different anime universes. One of the most sought-after abilities is Moon Slayer, a powerful skill set , its design draws inspiration from Kokushibo in the anime Demon Slayer. This article will provide you with detailed guidance on how to efficiently acquire the Moon Slayer by following the correct steps.

What Is Moon Slayer?

Before you set out to acquire Moon Slayer, there are a few core concepts you need to understand.

Moon Slayer is a flighting style introduced in Sailor Piece's most recent update—the Moon Update. It is modeled after Kokushibo from the hit Japanese anime Demon Slayer. Characterized by his six eyes—featuring red sclera and golden-yellow irises—Kokushibo possesses an extraordinary presence and immense combat prowess within the anime, and he use the Moon Breathing. The visual appearance and in-game effects of Moon Slayer bear a striking resemblance to those of Kokushibo.

Another crucial element is the Upper Seal. This serves as the primary material required to unlock Moon Slayer; it is a legendary drop item that cannot be purchased or traded. Instead, it can only be obtained as a rare, probabilistic drop after defeating enemies—and acquiring Moon Slayer demands a large quantity of Upper Seal.

Now that we have learned the basic concepts, let's begin the preparations to obtain the Moon Slayer. The detailed steps are outlined below:

• Step 1: Farm for Upper Seals

 

• The Upper Seal is the prerequisite for everything that follows; you must farm a sufficient quantity of them before you can summon the Boss. The recommended farming locations are Lawless Island, Ninja Island, and Shinjuku. The enemies in these areas are high-level and respawn quickly, which can significantly boost your farming efficiency. Since the majority of the Upper Seals you collect will be used to unlock the Moon Slayer's F Move, gathering around 25 Upper Seals is enough to proceed to the next step.
  Tips:
  Equip high-damage weapons to increase your kill count per unit of time.
  Stack Luck Runes to boost your chances.
  Take advantage of weekend 2xLuck Events to accelerate your progress.
• Step 2: Summon and Defeat the Boss

 

• Once you have completed the preliminary farming for Upper Seals, head to Boss Island. Locate the Boss Summoner NPC, select Moon Slayer Spawn from the menu, and submit the following resources to summon the Boss:
  1x Upper Sea
  700,000 Money
  700 Gems
  Note: The Boss is of a high level; it is highly recommended that you prepare thoroughly before attempting the challenge.
• Step 3: Gather Materials to Exchange for the Moon Slayer


After defeating the Boss, you have a chance to obtain the following items: Demon Remnant, Lunar Essence, Moon Outfit, Crescent Shard, Six-Eyed Demon (Title), and Moon Crest. To exchange for the Moon Slayer, you must gather the following specific resources:
37,500 Gems
1x Moon Crest
4x Crescent Shard
9x Lunar Essence
16x Demon Remnant
25x Upper Seal
Six-Eyed Demon (Title)
Consequently, you will need to spend a considerable amount of time farming the Boss. If you wish to increase your item drop rates, you can choose to challenge higher-difficulty versions of the Boss—though, naturally, this requires you to possess sufficient damage output. Once you have collected all the necessary materials, return to Boss Island, locate the Moon Slayer Trainer NPC, and submit the materials to successfully obtain the Moon Slayer.
• Step 4: Unlock the F Move


If you wish to obtain the ultimate Moon Slayer, unlocking its F Move is an absolute necessity.
First, you must equip the Moon Slayer and master its basic usage. Next, you need to acquire an Upper Clan—this can be obtained by rerolling your clan affiliation (it grants a 40% damage boost, 50% increased maximum health, 12% increased melee damage, and 12% increased Luck). In addition to this, you will need to gather the following materials:
2x Moon Crest
10x Crescent Shard
85x Upper Seal
Yes, that’s right—you will need to spend a significant amount of time farming the materials mentioned above. The entire process is quite lengthy, so please be patient.
Once you have gathered all the necessary materials, head to the hand-shaped statue located to the right of Boss Island. Find the Moon Slayer F Move Mastery NPC, submit your materials, and unlock the F Move.

With this, you have completed all the steps and obtained the fully realized Moon Slayer. It will drastically boost your damage output, allowing you to navigate the game with greater freedom and prowess—much like Kokushibo himself—thanks to your formidable combat capabilities.

Tips for Getting Faster

• Fight the boss with a team. Kokushibo has high damage, so fighting with other players increases your chances of winning quickly.
• Use high-damage fruits or weapons. Strong abilities can help reduce the boss fight time significantly.
• Server hop if necessary. If the boss is on cooldown, switching servers may help you find a fresh spawn faster.
• Prepare healing items. Kokushibo’s attacks can deal heavy damage, so having healing items or defensive abilities is helpful.

The entire acquisition process involves at least three stages that require a significant amount of time to gather materials. If you lack the ample time needed to grind for drops—or if you have already invested a great deal of time yet still haven't managed to complete the collection—you might consider an alternative route: you can simply find a trusted Sailor Piece Shop and buy the Moon Slayer directly. In no time at all, the Moon Slayer will be in your hands, ready for immediate use.
