How to unlock the Yatousen
Here is how you can unlock Yatousen in Ninja Gaiden 4:
Step #1
Progress through the story until you reach Chapter 3: Phantom Pleasure Quarter. You’ll face a variety of human and yokai enemies in narrow corridors and stage arenas.

Step #2
At the end of this chapter, defeat the Kitsune Courtesan, the guardian of the first major seal. She relies on speed and illusion attacks, so precision weapons like the Dragon Sword work well here.

Step #3
After the post-fight cutscene, the seal will shatter, and Yakumo automatically acquires the Yatousen. It appears in your weapon inventory and can be equipped immediately for future chapters.

How to use the Yatousen effectively
Mastering the Rapier form
The Rapier form is all about agility, parries, and pinpoint hits. It excels at punishing isolated enemies and striking after dodges.
- Focus on quick thrust combos and perfect counters.
- Use dash attacks to maintain pressure while keeping distance.
- Employ precision pokes between enemy recovery frames.
- Keep moving — standing still reduces your survivability drastically.
Using the Lance (Bloodraven form)
Activating Bloodraven form transforms the Yatousen into a powerful lance, giving you access to piercing drill attacks and devastating finishers.
- Use this form against armored or large enemies.
- Charge your attack to break through guards or shields.
- Combine with Izuna Drop setups for high-impact combos.
- Be mindful of slower recovery; time your hits strategically.
