Chakra Fruit

The is a fruit bore by the Shinju.

Overview
The Shinju would bear the Chakra Fruit once every thousand years. The fruit contains chakra, which originally belonged to the Shinju alone. Though it was forbidden to consume this fruit, Kaguya Ōtsutsuki committed the taboo of eating it, gaining chakra and unrivaled power for herself, with which she was able to quell all wars. When her two sons were born, they became the first two humans to be born with chakra. The Shinju, enraged at the theft of its powers, took the form of the Ten-Tails and attempted to retrieve its chakra from the world.

By consuming the fruit, Kaguya was able to manifest a Rinnegan resembling the Shinju's as a third eye on her forehead, allowing her to cast the Infinite Tsukuyomi. By utilising this technique and God: Nativity of a World of Trees, it is possible to regather the chakra of all living beings throughout the entire world, assimilating them into a single being once again, thus allowing the Shinju to grow a new Chakra Fruit in place of the one Kaguya consumed.
