Abi's trident

Abi's trident was gift to Princess Abi from Naraku.

History
Naraku wanted Abi to open a path to the border of the Afterlife for him so he could obtain a shard of the Shikon no Tama. He promised to help her collect human blood at a much faster rate than her usual speed for her mother Tekkei in return. He produced the trident from his bones and lent it to her. When Abi confronted Inuyasha and his friends for the first time, the trident was able to protect Abi from Inuyasha's attacks by erecting a barrier around her.

After repeated encounters with Inuyasha, Abi decided to betray Naraku for having been dragged into their fight. She and her demon birds attacked a castle that she believed was affiliated with Naraku. She was once again confronted by Inuyasha. During the battle, she noted that the trident was the one good thing that came out of her deal with Naraku. She escaped once again.

Naraku approached Abi after her attack on the castle. It was at this point that her mother Tekkei had fully recovered. The two of them attacked Naraku. He was soon devoured by Tekkei. Inuyasha and the others arrived soon after and battled Abi and Tekkei. Naraku then emerged from Tekkei's body and killed her. Abi was prepared to attack Naraku with the trident, but it disintegrated both itself and her right arm. Naraku killed Abi moments later.
