Oni of the Forbidden Tower

The was an oni that was sealed inside a tower until it was freed by the dark miko Tsubaki.

History
Over 110 years before Inuyasha was sealed to the scared tree, this oni was sealed away by a priest inside a pagoda that was known as the "Forbidden Tower of Many Treasures" after many of his disciples were killed. It was each generation of priests' duty to maintain the seal. Tsubaki was told as a child that it would one day be her duty by her master.

During the story
Tsubaki returned to the temple she trained in after she was defeated by Kagome and Inuyasha. She used the priestesses Momiji and Botan to distract Inuyasha's group while she worked to break the oni's seal. She is able to open the pagoda doors, but there were other seals placed down below. When she finally broke the last seal on the oni, it was furious that he had been sealed and threatened to kill Tsubaki for it. She tempted the oni with the promise of power from the Shikon no Tama that was in her possession. As it came at Tsubaki for the jewel, she absorbed him with her right eye. Inuyasha, Kagome, Sango, and Kaede then showed up to confront Tsubaki. She expressed how much demon power was flowing through her and began to transform. Inuyasha and the others left the pagoda after Tsubaki's transformation was causing it to collapse. Tsubaki emerged as a giant red oni. She proclaimed that she would have eternal life with all this power. Tsubaki begins to attack everyone when her new powers. The oni is eventually destroyed by Inuyasha's Bakuryūha, but Tsubaki survived for a few moments before she died after a saimyōshō stole the jewel from her.
