Kiri the Current Compass

A new member of the crew

Kiri and the Wandering Watts

High above a steaming mountain spring, the northern lights once touched a young kirin’s glass antlers. From that night on, Kiri could hear wasted energy as a faint, lonely buzz.

When winter winds scattered the spa’s watts into the snow, Kiri followed their glow. Her antlers sorted every watt by season—cool blue for winter, fresh green for spring, golden amber for summer—and her little efficiency charm pointed toward the gentlest path home.

Now she travels with a flock of tiny watt wisps, helping every hot tub stay warm without losing its way. The crew calls her the Current Compass.
