Per Furinkan: "The ghost that Suzu brings out to torment Kuroboshi III is Sadako Yamamura (山村貞子) from the Ring films. In the manga she comes out of a television set like in the films, in the anime she is shown coming out of a pipe."

I guess they changed it for the anime adaptation of this chapter. Wonder why. I completely forgot about this gag, so this makes me feel better about using a Sadako-like ghost for my Rumic Nendoroid display thing...
