📅 Daily Yokai Encyclopedia

Drawn by the city’s flicker and the simultaneous cheers of social media, it appears when everyone chases the same moment in the same frame, stretching its shadow long. It pinches the boundary of waxing and waning like a thin bookmark and rounds only the moon seen through lenses. In dreams it seeps dusk through gaps in blackout curtains, planting a déjà vu of conference rooms and classrooms suddenly sinking into twilight. Those caught by it feel anxious that they “didn’t capture it” even after witnessing celestial events, and on full-moon nights they search for missing crescents. Rarely, for those who observe carefully and honor record and experience separately, it returns the image with a slight rim of shadow left.

The more learning tilts toward tablets, the more often it appears, turning problems into tangible forms to restore a sense of touch. It subtly shifts difficulty to let safe failures stack up. When the block tower holds steady at the peak, understanding sets in, and if it falls, it offers a new angle. For parents and teachers, it rings like a wind chime to cue the right rhythm of guidance.

The Cooling Oni is a yokai born from people overusing air conditioners to escape the summer heat. It usually wears a cute face, breathing out a soft “haa” of chill to cool a room. When it gets carried away, it turns the space into a deep freeze and drives residents to sneezing fits. In winter, it is said to quarrel with the Kotatsu Yokai. Some say if you forget to turn off the remote before sleep, the Cooling Oni slips into your dreams and whispers, “Stay cool a little longer.”
