Arc System Works and 4Gamer have published a video where they show off the two new characters Naoto and Hibiki. Even though it's all in Japanese, there's still a lot to be learned about how these characters work.
Interesting, that doesn't look like a placeholder date either. Doesn't seem to be on the US store. Also, I wonder why it's Revelator 2 instead of Rev 2. Will this be the localized title?
Edit: Actually, doesn't the official English site say Rev 2? And that Amazon page is kind of weird. Just read the product description.
