Mask-san begins to test Masaru. He asks a riddle: “Kill one to save five. But the one you kill is the only one laughing. What do you do?” Masaru, thinking it’s a game, answers with a joke: “Kill the serious ones first! Laughter is sacred!” Mask-san goes silent for a full 10 seconds (an eternity in audio drama).

It’s rare to find something that makes you laugh out loud one moment and then puts you on the edge of your seat the next. It plays with the tropes of the "stalker/killer" genre but subverts them through character interaction. Is it a horror story? A dark comedy? A strange slice-of-life? It manages to be all three.
