Okay, I'm calmer now. Having a fifth go at the trailer, my hype has slowly grown from the zero it had gotten. There is basically one character, the female Pegasus Knight, that is very flamboyant and off-putting.
The main character character though looks very subdued and the apocalyptic wasteland in the end makes me hope the Neptunia-style tropes are not really played straight. Maybe like Midori was made so annoying to contrast with the other guys in Devil Survivor.
Maybe it IS like Devil Survivor, as it has high schoolers and some pretty awful character design, but its story is really dark and interesting.
I'm illuded easily, I know
True fact: I stopped playing Devil Survivor because I couldn't stand Midori, so that doesn't give me any hope.
