The Whisper of Muramasa Long Katana, featured in Assassin’s Creed Shadows, is renowned for its impressive damage capabilities. With elevated Weapon DPS, Posture DPS, and Ability damage, this long katana is a formidable choice for players who prefer a blend of aggressive tactics and strategic counterattacks, especially those playing as the character Yasuke.
Its unique engraving distinguishes it from other weapons by rendering adversaries vulnerable after a successful riposte. This quality makes it exceptionally effective for players proficient in defensive maneuvers, thereby enhancing their offensive potential.
How to Unlock the Whisper of Muramasa Long Katana

Steps to Eliminate All Five Targets
Obtaining the Whisper of Muramasa Long Katana requires completing the Kurai Eikyou target board in Assassin’s Creed Shadows. This mission involves tracking down five assassination targets scattered across the Yamato region, all associated with the People of Yamato.
1) The Messenger
Location: Nara Heartland, Yamato, southeast of Kofukuji Temple.
- Finding Method: Look for The Messenger in a field, admiring the flowers. He is solitary, making him a perfect target for a stealth approach.
Reward: Shade of Blight Naginata
2) Akiyama Agent
Location: Near Uda Matsuyama Castle, Yamato.
- Finding Method: Clear out mercenaries bothering a local village first. The Akiyama Agent is located inside the castle, where he is protected by many guards.
Reward: Repeating Fate Teppo
3) Blacksmith Agent
Location: Miyataki, Yamato, southeast of Utano Tower.
- Finding Method: Approach him during the night when he is isolated in a quiet area.
Reward: Encouragement Amulet
4) Katsuragi Agent
Location: Gokenin Manor, Katsuragi, Yamato.
- Finding Method: His whereabouts are revealed through a side quest, but he generally resides in a heavily guarded manor. Stealth at night is highly recommended for this elimination.
Reward: Boulder Fall Kanabo
5) Tsutsui Agent
Location: Koriyama Castle, Yamato.
- Finding Method: Found in the northeast section of the castle, he is within a fortified area. You can stealthily bypass many guards by entering through the rooftops.
Reward: Dragon’s Wrath Bow
Claiming the Whisper of Muramasa Long Katana

Upon successfully eliminating all five targets, return to Fuyu, your quest giver. She will instruct you to visit the persimmon tree located behind the Omiwa Shrine — the same tree where Kojiro first met Naoe and Yasuke. There, you will find the Whisper of Muramasa Long Katana awaiting you.
Additional Rewards for Completing Kurai Eikyou
Completing the Kurai Eikyou target board not only grants you the Whisper of Muramasa Long Katana but also:
- Six legendary weapons (including the Whisper of Muramasa).
- 5,000 XP for accelerated leveling.
You will also unlock two new skills:
- Kunai Assassination Damage III for Naoe.
- Silent Arrows III for Yasuke.
Given these offerings, the Kurai Eikyou target board stands out as one of the most rewarding side quests in Assassin’s Creed Shadows, providing top-tier legendary gear and crucial upgrades for both characters.
