So does anyone remember a conversation where it was mentioned in Swords of an honorable ruler that Kagome did not age when she traveled through time. I am going nuts thinking that I am the only one who may have seen and heard that in the movie.
I've seen the movie recently, so I actually know what you're talking about.
The conversation takes place when the Inutachi, Sesshoumaru's group, and the older youkai (Totosai, Myouga, & Saya) are sitting around a campfire. The subject of Saya's barrier/sheath comes up and is said to seal Sou'unga for about 700 years. Saya admits to only maintaining the seal for 200 years, and (I think) it was thrown into the well, thus transporting to 500 years into the future.
Shippou briefly asks why Kagome doesn't age through the portal, but no one could find a reason for it...and the matter is dropped almost immediately. Clearly, the characters don't pay attention to this as much as we do.
IMO, I can't say for certain if the whole non-aging thing makes Kagome immortal. Only Takahashi-sensei will ever know the answer to that. BUT, as long as you can come up with a somewhat plausible explanation for Kagome's immortality, it should be okay. As a fanfiction writer, you
are entitled to the amount of creativity that's put into your story. And because these facts aren't stated explicitly in the manga/anime, you have more freedom to explore.
Just make sure your plot is well thought-out and convincing, and you're all set.
