Hyu

 or Hyuu are wistful ghosts that roam parts of the overworld in and.

Characteristics and Weaknesses
Hyu appear much like Poes, but they haunt desolate and ruined buildings instead of the graveyards commonly associated with Poes and Ghinis, and as such will not appear from under graves or any other objects. Hyu appear to mean no harm directly, but they are likely to get in the way and can inflict two hearts of damage per hit. Link can defeat them easily, however, with a couple of slashes from the Master Sword. They are very common in the Village of Outcasts, in the woods north of the village, and by the graveyard.
