The final sentence in 輪郭 -Eternal Slumber-, is the first from [KR] Cube.
(“Demon come this way, towards the clapping hands”)
It’s another chant from a child’s game in Japan, like Kagome Kagome. The Western equivalent is ‘tag’. The chasing kid is blindfolded and can only try to catch the other children, because they’re saying this line and clap their hands.
