Thanks for this translation! "Extras" like this are why I don't unfollow a manga after the "end". There's usually an extra chapter like this full of bonus epilogue material. Sometimes more than one, and sometimes they drop years later.
Let's see the next book series based on the kids and their handling of their part spirit powers. We don't have to see Mom and dad. We know who they are
That was a nice little shot of sugar. This was such a lovely manga.
Edit: I want to see a manga about Konoha Suetsugi's relationship. Konoha really grew on me as the manga progressed. I really enjoyed her character. I really want to see Mayura Momouchi learn Mashiro's secret as well lol.
Extra chapters after a series end are always bittersweet. They remind us of the good times had and each time, bring the knowledge that the series is over.
