Chaotic Destroyer - S3.E43

Continuing his broadcast which is only visible to cardfighters, Takuto reveals everything about Reverse and the black rings in the sky scattered around the world. He explains that those are gates which grow with each fighter becoming Reversed, eventually enveloping the entire world in darkness. At the end of the broadcast, as Aichi and his friends come to grips with this revelation, Kamui finally succumbs to Reverse and challenges Aichi. Soon becoming overwhelmed by an increased number of Reversed fighters, Aichi and his friends escape along with Gouki, Nagisa, Emi, Mai, and Rekka thanks to the timely arrival of Shin.

Elsewhere, Miwa fights Kai using the latter's Kagero deck in an attempt to open his eyes. However, his efforts end in vain as Kai defeats him with Star-vader, Chaos Breaker Dragon while also telling Miwa that he became Reversed of his own volition to become as strong as Aichi and Ren.

At Card Capital, Aichi and his friends decide to confront Takuto for information. Suddenly, Miwa, now Reversed, appears and tells them that they will have to fight Kai before getting to Takuto. He also tells Aichi that he and Ren are what drove Kai to becoming Reversed in the first place. After Miwa takes his leave, everyone resolves themselves to press onward, but Aichi is showing signs of hesitation after what Miwa said...
