So I was browsing through the web when I saw this!
It's the english dubbed episode of the final act! I'll have to admit the quality isn't very good, I mean you can totally get through it but the sound goes in and out, plus the final product was edited pretty badly.
I didn't really look into why, but it's claimed that the producers left it like that.
Also remember that some of the voices changed! I actually don't hate Kagome's new voice, but it doesn't scream, "WEDNESDAY, 8:30P.M., [ADULT SWIM]!!!" Plus I thought Kanna sounded way different which doesn't make that much sense to me. Kagura and Kanna are voiced by the same person so it shouldn't be that difficult to get, then again Inuyasha's voice is by the same guy for the first half of the series but off a little too.
I honestly recommend watching the Japanese with the English subs if you haven't already. It's rather good! Though I am a Naraku fan and love Paul Dobson's voice. Haha.
Anyways, I thought I'd update and let all of you know!
