葬送のフリーレン

Frieren, an elf mage who once helped Hero Himmel and his party slay the Demon King, lives on for centuries while her human companions age and pass away. After Himmel's death forces her to confront how little she understood the friends she outlived, she sets out on a slow journey across the land. Along the way she takes in Fern, an orphan girl Heiter raised, and begins teaching her magic, and later the young warrior Stark, trained by Eisen, joins them on the road.
