I'm so happy the site is back up. I had a dream about this series! It was about the future of the temple, but no spoilers because it's complete nonsense. XD
Chion died and became a spooky ghost who lingered at the temple. People could talk to her, but they probably wished they couldn't. Her ghost was exorcized. Life continued at the temple, Gen took up some of Chion's chores. He tried on a garment of hers when cleaning her room. He thought about the future and decided that someone else could become the head priest, but he wanted to live in the temple if he could. He thought selling insurance would be a good job. Fast forward a decade or two and in Chion's room was a sturdy looking lady. No, it was Gen, dressed like an older Chion.
