Naru

Naru is a creature who adopted Ori, a guardian spirit, after Ori fell from the Spirit Tree during a storm as a newborn. She raised Ori as her own. When Kuro stole the last light from the Spirit Tree, causing the loss of the three elements and the forest to wither, Naru died of starvation. Later, after Ori and Sein restore the Water element, Gumo—motivated by finding a light stone—uses his clan treasure to revive Naru and takes her to where Ori is.

When Kuro attacks Ori and Sein after they exit Mount Horu as the volcano's fire spreads, Naru arrives to protect Ori. Kuro softens, remembering the pain of losing her children, and grabs Ori, flying to the Spirit Tree. The Spirit Tree emits a flash of light that restores the forest, but Kuro sacrifices herself and is consumed by the light, turning to stone and dust. Afterward, Naru watches from afar as new spirits are born, then goes home, where Kuro's last egg now rests, just in time to see it begin to hatch.
