Okay, I'm sure you're wondering why I took down the voting thing and the reason is because I came up with a rather interesting plan thanks to some comments I saw as well as an idea I had out of the blue, a plan that I'll fill you in on at the end of V3 as I would just end up having to explain it again later.
But it should involve aspects from the first three options. Though she won't be traveling to any other world, well, she kind of will but also not really...it's hard to explain without going too much into it and I myself am going over the idea in my head, so like I said I'll explain more down the line.
P.s. sorry for any miss spellings, I'm tired.
