Kusanagi is one of the most grind-heavy mythical swords in Rogue Piece, tied directly to Sasuke Uchiha from Naruto. Unlike normal legendary weapons, this sword needs multiple rare boss drops, a title, and a large number of gems before you can even purchase it. So, to help you get this sword, this guide explains every step clearly so you can avoid wasting time or missing requirements.
How to Get Kusanagi in Rogue Piece
Kusanagi is not dropped directly as a loot drop or boss reward. Instead, it is purchased from the newly added Kusanagi Seller NPC located in Konoha Village. The seller will only complete the transaction if you already possess all the required items and the correct title.
To obtain Kusanagi, you need to farm the Sasuke boss extensively, collect multiple rare materials, and get lots of Gems. Only after meeting every condition can the weapon be unlocked. Here are all the requirements to get Sasuke in Rogue Piece:
| Requirement | Source |
|---|---|
| 30,000 Gems | Quests/Bosses/Chests |
| Kusanagi Katana | Sasuke Boss drop |
| Rinnegan Eye | Sasuke Boss drop |
| Sharingan Eye | Sasuke Boss drop |
| The Last Uchiha Title | Sasuke Boss drop |
Once purchased, the Kusanagi sword is permanently unlocked and does not consume the title or materials afterward.
How to Become Sasuke in Rogue Piece
Becoming Sasuke is not a transformation or spec in Rogue Piece. Instead, you need to complete the entire progression path tied to the Kusanagi weapon, title, and outfit. You need to farm the newly added Sasuke, The Last Uchiha, boss, and equip his title and weapon. There are no additional traits or specs required, but the grind is long due to extremely low drop chances.
How to Get Sasuke Outfit in Rogue Piece
The Sasuke Outfit is a cosmetic item dropped by the Sasuke boss. It does not provide combat stats, but it is required if you want to visually complete the Sasuke build. The outfit drops independently of the weapon materials, meaning you can obtain it early, based on your luck.
It is not required to purchase Kusanagi, but it is commonly farmed alongside it. Because Sasuke has multiple valuable drops, you can naturally obtain the outfit while grinding for the sword materials.
