Elluka in JoC is the same thing as Margartia in SCAP. We’ve been looking for an explanation as to how Eve got out of MA.
Elluka is the same.
They’re broken-off and left-behind pieces from a messy and accidental soul fusion. MA is not the same person as Elluka. She is, IIRC, explicitly in Pierrot referred to as a new being with a singular soul, and since souls define people, that means she’s a new person.
Meaning that unless you consider Elluka = MA, then I don’t think it counts as incest, but that’s neither here nor there.
The point is that no, Levia didn’t separate from MA and snatch a new body. A fragment found its way into living. And given that she killed someone for a Vessel of Sin, it sounds like, similar to Eve, she’s carrying on with the work Levia was undertaking when the fusion happened–just as Eve was carrying on making GIFT as the Margarita fragment.
Studio Pierrot shipped the fuck outta IchiRuki. All the openings and endings we got were really Ichigo/Rukia focused plus some cute added bits in there too, and their voice actors really liked the idea of them getting together.
Vocally hopes Studio Pierrot pulls a FMA and writes an alternate ending to Bleach where everything makes sense, everyone gets what they deserve, everyone is in character, some plot holes are freaking filled, and there is narrative closure for fans, characters, and plot.
