I'm just gonna throw out there that I think the voice screaming AKAGI-SAAAN at the end is one of the two Ryuus (Souryuu or Hiryuu).

Also I think its not so much "memories of past self" rather than they are feeling "instincts" that lead them toward things that happened to their historical selves... or something, or that the story is actually functioning as an alternate WWII. The Abyssals knowing their radio codes is likely coinciding with how the Allies were able to successfully decode Japanese radio codes and frequencies, but unlike in the anime the IJN never knew until it was really, really, too late.
