if your still intersted in doing redos or filling some gaps between chapters check out A Returner's Magic Should Be Special, or maybe Dimensional Mercenary. One of those might interest you.
I am impressed that Rubia's character did a 180 in a believable way. I wouldn't have expected this when reading the first couple of chapters. Tbh, the beginning is pretty rough but now it's very cool to see the pieces fix together.
