A yokai born from the learning spirit dwelling in number blocks, awakened by the fingertip memories left behind in the screen age. It teases children with little tricks—nudging answers by a digit, swapping pieces—to sow mild confusion, yet through play it helps them build a sense of quantity and calculation. The more it is touched and stacked, the more its form shifts, guiding modern learners to grasp the meaning of numbers with their bodies.

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.
