Yōmeiju

was a carnivorous tree yōkai that used vines capable of dissolving barriers to prey on other yōkai. It was put under seal by a priestess, but was later revived by Naraku using a shard of the Shikon Jewel. Naraku absorbed the tree so that he could use its vines to reabsorb the Infant.

Manga vs. Anime

 * In the manga, it was mentioned that Yōmeiju was sealed by a monk 100 years ago. But in the anime, the person who participated in the sealing process is changed to a priestess, 50 years ago.
