A Treant Sapling is a withered tree with a pale trunk fifteen centimetres in diameter and two metres in height, comparatively smaller than the old trees in the forest. Pale lights shine in the two small knotholes in its bark and its branches stretching out to the sides wave like slender claws.
While Kirito was explaining about the Forest of Wavering Mists, Asuna notified him that a monster was watching them. The Treant Sapling stared at Kirito for a few seconds, then pulled out its roots out of the ground and began walking towards him. As the tree suddenly began dashing at full-speed, the tree opened its third knothole and the tree howled. After three minutes, Kirito cut off both of its arm branches and Asuna penetrated its mouth with her Wind Fleuret +5, causing the tree to explode into polygons.
