I can’t say I fully grasp all of the metaphysical aspects of Dimension W, but as Kyouma delves deeper into Easter island, both he and I are getting the answers we wanted, and things are starting to make a tentative kind of sense.
Take the sudden confrontation with Loser. He’s not there to kill Kyouma, just stop him. Kyouma has no memories of went on there, so Loser feels he has no right to desecrate the ground where he lost his wife. Then one of those mysterious spheres appears and Kyouma makes contact with it, and passes out. We didn’t know until this week what happens next.
Kyouma wakes up to Al looming over them; he’s in a memory of training with Grendel. Then news comes of a revolt in the African Union, where Kyouma and Prince Salva’s lives overlap. War is official declared by the leader of the scientists rebelling against the New Tesla execs, a guy named Haruka Seameyer, who looks like a Bleach villain and demands “scientific freedom” to shape the world how he sees fit.
Prince Salva is set upon by an assassin, but Lasithi takes a bullet for him. When Salva orders the assassin killed, Lwai shows up right behind that assassin, and Salva ends up blasting both of them. Seameyer was there too; always present when “confusion” crops up.
Hell, we even get some Loser backstory, as a younger, strapping Julian Tyler—who has all of his skin!—is working at Central 61 (AKA Adrastea) with his wife Sophia (Ellie’s mom) when Seameyer starts his rebellion and makes Julian choose a side.
While not in one of those weird spheres like Kyouma or Salva, the place itself is filled with memories for Loser. Only when he reaches ground zero of the dimensional calamity, there is only nothingness. He presumes he still needs at least one more Numbers to proceed.
Kyouma continues reliving the past, and when he spots Mira for a moment sitting beside his dying wife Miyabi, he realizes he’s being made to relive his past, perhaps in order to get him to question the choices he made and the possibilities that resulted from those choices.
Seameyer reveals he is the energy sphere, and like Loser seems to think Kyouma is uniquely suited for this kind of dimensional speculation or some such. This is the harder shit to understand, but suffice it to say a ghostly Miyabi reassures Kyouma that his choices were sound, and to trust in himself and not let Seameyer push him around.
Back in the real world, Mira sees the picture of Miyabi, and remembers Mary telling her that her own body was once meant for Kyouma’s wife, which is why they have the same exact height, measurements, and shoe size. With this in mind, and knowing Kyouma can’t help but be reminded of his dead wife and what could have been every time he looks at her, Mira comes to an understanding with herself.
She may not be Miyabi, but she wants to be someone worthy of having the body meant for her. She also wants Kyouma to know he can rely on her. So when another killbot descends into the tunnels, and their escape is cut off by nothingness pocket, Mira resolves to protect Kyouma until he wakes up.
It’s the least she can do for someone who, however indirectly, was responsible for her being able to exist, and who despite his rough manner with her, has given her a chance to be a productive individual.
