FAQ

How hard are the Byakue fights?
PowerPyx rates Byakue 2.5/10 and Byakue (Enhanced) 3/10 — fights 1 and 2 of 18, the game's opening bosses. Once the deflect timing clicks, the fight is a formality.
What is the basic Byakue strategy?
Dodge when he is not swinging his axe, deflect when he is. With the timing nailed you can counter every one of his attacks with Issen — except the shoulder charge and the sprint charge, which are dodge-only.
What is his blue attack?
He occasionally lashes out with his talisman hair — a blue attack. Dodge right before the hair makes contact, per the in-game prompt.
What changes in Byakue (Enhanced)?
One wrinkle below 50% health: he wreathes his axe in Malice. He will either slam it into the ground — jump right before impact — or spew pools of Malice you want to steer well clear of.

This is the boss guide for Byakue in Onimusha: Way of the Sword — fights 1 and 2 of 18, the opening pair of the boss list.

The core rule

The trick to this fight is simple: dodge when he is not swinging his axe, and deflect when he is. Once you have the timing nailed, you can counter every one of his attacks with Issen — with two exceptions:

  • The shoulder charge
  • The sprint charge

Both close distance fast and are dodge-only. Everything else is an Issen opportunity.

  • The talisman-hair lash — his blue attack. He lashes out with his talisman hair; dodge right before the hair makes contact, per the game’s prompt.
  • Rinse and repeat until he is down.

Byakue (Enhanced, fight 2)

The rematch plays out much like the standard Byakue — same strategy almost across the board, bar one wrinkle. Once his health drops below 50%, he wreathes his axe in Malice:

  • The Malice ground slam — dodge it by jumping right before impact.
  • The Malice pools — he spews pools of Malice; steer well clear to avoid bleeding health.

Everything else about the fight remains unchanged.

Where this sits on the road

Byakue opens the roster; Dohatsu-ten follows at 3-4 and the Nue duo at 5. On the Platinum push both fights return in Boss Rematch — part of the Glutton for Punishment sweep on the trophy roadmap.
