For my fellow splitstaff enjoyers, dragon dance absolutely destroys this yokai. At the start just run towards the purity pot and break it, then get right on it and just spam dragon dance and watch him getting melt. Save your yokai shift for the dark realm to destroy the red orb.

Any bosses that keeps running away from you is really boring, easy but boring boss. Couldn't they make this one better instead of stupid bird who kept flying away and ran from players?

How much Astral Wisdom do you need to understand this guy? I've beaten the game, all the missions & got all the soul cores exvept the kodama one & this is the only yokai I can't understand

Poison is a great was to whittle down his health while he's flying

Will an Onmyo Magic build find this fight easier? Like just spam some Fire Shots/Explosive Shots at the bird?

In my oponion, this is the only bad designed biss that the game has to offer, and it isn't because he's hard.
His moveset is really static and easy to learn, but the carpet bombing of homing dark things was a true *******, especially during the dark realm phase.
Without takingbin consideration that if you're using light armors and you're still in early-mid game, the grab attack which he spam is a death sentence.
And it isn't always easy to dodge it, since sometimes he'll chain it during his combo and when you have an opening for attacking.

His diving attack is one of his biggest openings, once he hits the ground he's vulnerable for some time, so bury your head up his *** and wail on him at those moments.

He's quite trivial until his yokai realm phase, even then, it's mostly just because he's hard to even see as his moveset isn't changed up too much.

Also drops the smithing text Merchant's Attire.
