Well that was an amazing episode.
So to start with, it is nice to see a speed duel that finally feels fast paced. I didn't had issues about it in the previous duels, but I did want to see a fast paced speed duel, so there is that. The link summoning animation was also shortened this time and were pretty short, and I am glad for that.
Akira and Aoi's character establishment was great. The brainwashing trope was actually refreshing this time and was more of a berserk mode rather than the usual brainwashing, and I honestly didn't expect that.
The OST was amazing and reminded me why I loved DM/DSOD's OST so much.
My only nitpick is that Aoi's skill is completely trash. It basically gives the opponent a Card of Demise without any of the costs only to deal some burn damage which can easily be dealt with(either by negating the monster's effect or by using an effect against the burn damage, like Yusaku did)
As for the preview...Yusaku is even more angry at Hanoi than before. I like how much of an anti-hero he is. This is gonna get good.
