Fairy Bokku is a diminutive tree sprite with an acorn-shaped cranium and who ends every phrase with "bokku!"  When the Balban attacked the Ginga Forest Village, he was the only one to escape before it turned to stone, carrying an amulet he was instructed by the village elder to deliver to the Gingamen.  He usually stays in Moak's chamber as his combat abilities are next to nothing.
