My, she has grown. Very nicely done.
... Okisaki. It's hard to guess without seeing the kanji, but the most plausible reading, I think, would be 置き先 -- not an existing word I don't think, but it would fairly naturally read as "something/someone sent forward".
Five seeds... Five elements, five countries.
... No, I don't quite see it. I think it's something along the lines of: "there is literally no safe place in the world for these, so to preserve them, we can only bring them forward in time, to skip some dangerous moment." But I'm not sure what they are, yet, or what they might be used for -- since it sounds like they can be used.
(I mean, the obvious guess for 'powerful important seeds of which there can be only one a timeline' is something to do with the Ten Tails and the Shinju, but. That's again just speculation, and I'm not sure what they're for. Certainly not to grow the Shinju, when the Outer Path Statue exists. And that explanation doesn't explain why you'd want exactly five of them.)
