Coming back to this, and I have to say Kaeha's love is one of the most beautiful things ive ever seen in manga/anime media. She knows that her time is limited, so she solidifies herself as something that Aesir will never forget- be it the way of the sword that was honed through love, her dojo, her successors--- All of it, all of it. All so that Aesir would always have something to come back to, even when she's long gone. The amount of selflessness and love she has is just beyond what any person would do- I'd love for the author to make it so that there is a timeline where both of them end up together, she deserves at least that, doesnt she?
