The end of the story is good, but I'm not completely satisfied. First, as time passed, "Sensei" remembers all the happenings, as as she is reborn it is explained in the series that she doesn't forget any memories she gained. While Iris and Sara don't remember anything, Iris was reborn at the same time as Sara, they both met at the same school they attended years ago (before they both reincarnated) and then the same story repeats itself, the difference that a way was found. to prolong the lives of brides, so at the end of the last chapter we see Iris and Sara as school teachers who studied and do not remember their last reincarnation, it's a shame, because it was such a beautiful story! While Aoi and Shion know what happened they prefer not to intrude on Iris and Sara's "new" life so they don't suffer and remember what they both went through.
This was translated to Spanish a long time ago. It's a 3-chapter story, so next chapter is the final one. If you just can't wait to know the conclusion, and have ok Spanish-reading skills, go here for chapter three:
Does someone knows more about it? I read that it has been released in Japan the new manga spin off of Kannazuki No Miko! And there are some people posting random chapters of it on Instagram. Also there are people saying it will be released a new anime of it. Can someone update me, please? Where can I read the new manga?
