Lumi stands at the front of a statistics classroom, reaching into a large bowl of numbered tiles and pulling out handfuls at a time while a bar chart fills in on the whiteboard behind her; next to the bar chart is a thick shaded band drawn around a percentage — a visual bracket with arrows on both ends labeled '±4%' — showing students that the true value could land anywhere inside that highlighted zone, not at a single point.

Lumi — a curious silver fox in a data-analyst's vest — stands at a large whiteboard covered in a symmetric bell-shaped curve drawn in chalk, holding a ruler against the curve's center line and tapping each labeled band with an enthusiastic grin, surrounded by stacks of data cards labeled with measurements like heights and test scores.

Atlas stands at a whiteboard in a sunlit physics lab, sketching a smooth U-shaped curve on a coordinate grid while a model projectile launcher sits on the bench beside him, ready to fire.

Lumi stands at a large coordinate-plane drafting table inside a sunlit math studio, pressing a ruler firmly along a colored line and drawing it across the grid until two bright lines cross at a single point, then circling that crossing with a bold marker and writing the ordered pair beside it.

Atlas stands at the base of a tall lighthouse on a rocky coastline, holding a surveyor's transit and a sketch pad. He has measured the angle of elevation to the top of the lighthouse and the horizontal distance from his feet to its base, and is now writing side ratios in a right triangle diagram in his notepad, showing how a single angle locks in every ratio of the sides.
