Unicorn keepers; female on the left, male on the right.

Unicorn Keepers are the guardians of the rare creatures called Unicorns in the Unicorn Forest. On Third Earth, there is a male and female pair of Unicorn keepers. Although married to each other, neither keeper on Third Earth seems to have individual names.

It's unknown if there are other members besides the two.

Unicorn keepers also maintain the crystal that produces the Bridge of Light over the River of Despair.
