Aekanaru summary:

Sadai, looking for a place to die, headed deep into the mountains. There he encountered a mysterious and gentle girl who had lived alone in an abandoned village for 150 years, continuing to serve an intangible god. A man that had failed to die and a widow with a graceful aura — from the remains of their wasted lives, the two of them begin a new chapter of their story.
