[Aoi Kurenai]

The production meeting was held a few days ago and pretty much all of the character bios, cast, and staff were revealed:

To sum it up

Riku has wanted to be a hero since he was a kid, inspired by an old TV show he and his best friend, Moa, used to watch. His home is destroyed by Skull Gomora and he ends up spending the night in an observatory basement, where he finds a secret base and is given the ability to transform. When he transforms, he starts to realize he's the son of Belial.

Riku's actor is singing the opening and Voyager are doing the ending. Kenji Kawai (Nexus, Ghost in the Shell) is doing the music for the series. So at the very least, it'll have a fantastic soundtrack.
