great teacher onizuka behind the voice actors one piece stampede timeline
They really put together a great cast. I'm especially impressed with the announcer Sayaka Katahara(voiced by Mana Hirata). She really did a fantastic job playing the role of "Master of Ceremonies" and doing super hype fighter introductions and commentary.
I can't speak on the dub but it does have veterans like Johnny Yong Bosch so it should be pretty good even if they used the same actors for multiple roles unlike the Japanese version which is understandable.
- Enjoyment
This is where I'm going to diverge from looking at the anime as is.
Honestly it was just ok. Even before the anime aired I knew it would be hard to adapt it properly and I was correct. A lot of character interaction was axed as well other events that took place before the tournament started that are referenced later in sub plots and in the plot itself. What makes Kengan Ashura is its characters more than the fights.
In the manga they're so individualized with their personalities. We don't get to see that in the anime due to them removing interactions.
