Somari and the forest spirit anime

The world is ruled by spirits, goblins, and all manner of strange
creatures. Human beings are persecuted, to the very point of
extinction. One day, a golem and a lone human girl meet. This is a
record of the pair, one a member of a ruined race, the other a
watchman of the forest. It tells of their travels together and of
the bond between father and daughter, but the golem can only live
for another year or so, he must find other humans in order to get
her with her own race before he dies.
