A Cheerful Grim Reaper and a Gloomy Entertainer

"Hello there! I've come from the underworld to inform you of the end of your life! I'm Karimita, the reaper of death!! May I ask your name?" "...Hello... I'm Kage no Ura..." "Hmm... Even though I'm the one who suddenly intruded, it's strange to say this, but you're the first person I've met with such a muted reaction, Kage no Ura. Normally people would be shocked and lose their footing when a reaper suddenly appears, or they'd cry out in fear as death closes in on them. Shouldn't you be showing at least some kind of reaction?"
