Shinju (Shinobihax)

The Shinju(神樹, Lit. "God Tree") is perhaps the most powerful object in The Noble Blood universe.

Background
The Shinju undergoes its life cycle via "Samsara" or "Six Paths" as some have more commonly come to refer to it as. The Power of "The Six Paths", ultimately eternal, final, and flawless in its nature, is something which The Shinju is dwells within, and as such does never truly experience death. It's eternal life cycle via Samsara is identified as "Six Life Cycles God Rebirth". Rasetsu Uzumaki equates The Shinju's Life Cycle to The Rinnegan which The Shinju is responsible for creating.
