Kenshi Yonezu - Shinigami (死神)
Ajarakamokuren, tekerettsu no pa.
A short version of track 3 from Kenshi Yonezu's eleventh single, Pale Blue.
Shinigami are Japanese gods of death, and the song is inspired by a classical rakugo performance called Shinigami, in which "ajarakamokuren, tekerettsu no pa" is an incantation for warding them off.
