In reference to a collaboration horror game stream with Shishiro Botan, in which Botan (playing the game) runs into a graffiti in a wall that reads out "KNY" - when asked by Lamy what it stands for, the two reach the conclusion that it stands for "kuyashii-nakigao-Yukihana Lamy" (Frustrated, Crying Yukihana Lamy)
