Saya's hardly the reliable type.
After the death of Inuyasha's father at the ruin of Izayoi's mansion, Saya, Myōga and Tōtōsai were following their master's last will. Tessaiga was sealed inside Tōga's tomb at the Border of the Afterlife with the Black Pearl, and Tōtōsai made sure Sesshōmaru would receive Tenseiga (he did not give Tenseiga to Sesshōmaru in person as he feared he would have been killed, but he gave to Bokusenō that the Tenseiga is for Sesshōmaru). They were unsure about what to do with Sō'unga though. They couldn't give it to Sesshōmaru, who desired power and would kill them for being given Tenseiga, and neither they couldn't give it to Inuyasha, as he was merely a baby at the time. Saya suggested he'd hold the sword off quietly for 700 years, and placed it in the Bone-Eater's Well in the land of Musashi.
During the story
About 200 years later, the sword ended up in possession of Kagome's family. In the 20th century, the seal broke. Therefore, Saya tried finding a strong demon, in hopes that they would be able to control Sō'unga before it could unleash chaos in the modern world. He eventually found Inuyasha and Kagome. Inuyasha did not know who Saya was when he arrived (Inuyasha was an infant the last time he met Saya). Saya showed the two of them a vision of what Sō'unga was capable of if it was left unchecked. The world was devastated and littered with bones. That motivated Inuyasha to try and subdue the sword.
When Inuyasha grasped Sō'unga, he was taken over, but regained control for a short period of time. To prevent it from harming anyone in the future, Inuyasha went into the past. Kagome was angry that Inuyasha did not accept her help. She asked Saya if he had the power to suppress Sō'unga. Saya was unsure that he could.
Saya and Kagome retuned to the Feudal era to stop Sō'unga. When they were greeted by Kagome's friends, Myōga accused Saya of slacking from his duties (as Sō'unga was released after only 200 years).
Inuyasha left his friends to find Sō'unga on his own after he was freed from its control. The others waited for Kagome to regain consciousness after she saved Inuyasha from the sword. As they waited, they learned about the history of Sō'unga. Saya explained to Kagome and the others that the only way to defeat Sō'unga was using Tessaiga and Tenseiga together. Everyone else knew that would have been impossible since Inuyasha and Sesshōmaru despised each other. Kagome asked Saya if he could seal the sword again, but Saya made a lot of excuses as to why he could not.
After Sō'unga was being wielded by Takemaru, he erected a giant fortress that was visible from a distance. Everyone was headed there to defeat Sō'unga. Before the battle against Sō'unga, Saya inquired to Kagome about why she was going to fight when she had no stake in the fight. He initially believed that it was because Kagome loved to fight, but Kagome stated that was doing this because she wanted to be with Inuyasha. Saya, along with Myōga and Tōtōsai did not understand her reasoning.
Saya was taken with Kagome and Rin by an ogre (Kagome had Sō'unga's sheath with her when she was captured). All three were taken to Takemaru's chambers. They soon escaped when Sesshōmaru arrived to save Rin.
After Sō'unga was destroyed by Inuyasha's Bakuryūha and Sesshōmaru's Sōryūha, Saya revealed that he knew of his master's wish for the two of them to seal Sō'unga into the netherworld by working together, but he did not reveal that. He initially stated that he withheld that information because he was thinking about what was best, but Myōga knew that Saya actually forgot to tell anyone.
Saya was last seen in Tōtōsai's forge where the swordsmith was forging a new blade for his sheath. It ended up as a small dagger (much to Saya's distress).
Saya is a slacker and is said to be unreliable since he didn't hold Sō'unga as long as he was supposed to. Saya said in a meeting with Myōga and Tōtōsai after the death of Tōga that he would be able to seal the sword for about 700 years. However, he was only able to do so for 200 years. He often tells people that bad things will happen after they already have, cementing the belief that he cannot be trusted with anything important.
Despite his flaws, Saya is still a very knowledgeable person. He is aware of things that not even Myōga or Tōtōsai know of (such as the existence of the Bone-Eater's Well).
Powers & Abilities
- Invisibility: As a spirit, Saya has the ability to make himself invisible.
- Barrier: Saya is able to put up a barrier to protect the humans from the effects of having the gate to the netherworld opened by Sō'unga.
- Movement: When a person like Kagome carries the sheath of Sō'unga, that causes to pull Saya, and when it stops moving and the sheath is down, Saya can do a little bit move.
