Yeah, that's suppose to be a fill in before the start of the series. They probably grew distant after the appearance of Gridman and/or erased her memories.

Hime and Samurai, the prequel manga, probably touches on this considering Akane is a major character here too and is a bit more socially active than the show. Only two chapters are translated, unforunately.
