Katune

Katune is one of the remaining angels of endworld
shortly after the Apocalypse the god of life and many of the angels vanished
after a few decades the goddess of death and almost all of the angels faded away
Katune is the last angel of sleep, and since sleep is something the remaining people still do she still exists
as food becomes more and more scarce and fights more common they sleep less and less and she's fading
