Cries in Kusoge

Hi everyone, I finally got around to making an account here.... Anyways, I have something of a theory surrounding all of this. So, based on a) the amount of emphasis given to Naoto's arcade b) the knowledge that XBlaze is prior to BE, and c) the events of Naoto's arcade themselves, I think we can safely say that the current Embryo is Raquel However, the issue that seems to be outstanding with that knowledge is that Es seems to have no relevance. After a whole lot of grasping at straws, I can only think of two reasons that Es would potentially be needed/sent to a place of relevance in Act III: 1- Es' Murakumo can serve as a substitute for the 'True Murakumo' that Nine/Nu are trying to create. The fact that Nine experienced all of Es' memories, had/has full knowledge of said Murakumo, and named the Nox as such makes me think that might be possible. This may result in Ragna becoming something he actually has control over(?) or something along those lines were it fused with him. 2- Es may have been given the Azure Eyes by the Embryo (assumedly Raquel) to serve as a substitute for Noel's(?). The only reason I really considered this possibility is because I can't see much purpose for needing two pairs, unless of course they aren't the same.
