Ninja Gaiden (2004) Walkthrough - Part 4.5: You Did (Not) Get All The Upgrades [Epilepsy Warning]

This is a Fiend Challenge so the usual warning applies. It's the entire point of the video so I'd just skip this wholesale honestly.
Anyway, this the the one Fiend Challenge I missed in Chapter 6. You can also get it in Chapter 7 apparently. It's where the last Spirit of the Devils upgrade that I missed was, but in NGB (which is what I'm used to) they move it. It's only thanks to a comment from 2008 I even knew where to find it afterwards, so if one "nicholasliu" from Neoseeker ever sees this, this one's for you. The music used during the Fiend Challenge is Vigaku, the theme of Ein from Dead Or Alive 2. I figure since Ein is really Hayate, and him and Ryu are bros, it fit... Also it's my favorite song from the game so I wasn't gonna not use it.
Original post that said where to find it for those curious:

This video has a bunch of flashing screens due to some of the attacks, many of which appear in rapid succession. If you have photosensitive issues or epilepsy, I’d recommend skipping it.
Also I thought about putting this after Part 4 since that’s where this happens, but I like the implications that Ryu finished the game then someone said “hey you didn’t actually finish it right.” and he had to go back and redo this.
