As the title said - this is PIKOTARO’s *PPAP (*Pen-Pineapple-Apple-Pen) “performed” y RYUK (from “DEATH NOTE Light up the NEW world”)!!! What a way to promote the film! hahaha
And in case you were wondering, seems this IS a legit collaboration!
"10 years after the Death Note murders, six Death Notes fall to the human world. Two people inherit the DNA of Light Yagami and L, and a deadly new game of cat-and-mouse begins..."
