Tamashii

The 'Tamashii were a lineage of [Ize Zumi] whose bodies could serve as a host for the Kami [Togashi]. Togashi was able to keep himself alive and his true identity hidden from the empire by switching from one body to another as time went on.

Togashi [Kokujinn] was a tamashii, but learned of his eventual fate, and rebelled against it. Using the powers he learned as an Ize Zumi, he mastered the arts of the Shadowlands, and later returned, manipulating [Hitomi].

Togashi Mitsu
[Togashi Mitsu] was a tamashii during the Clan War, who knew of his fate and journeyed as a hero during his life. When Fu Leng was defeated and Togashi was killed, he wondered what purpose he still served.

Togashi Matsuo
[Togashi Matsuo] was born a tamashii after Togashi's defeat, making his purpose somewhat of a mystery.
