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 belongs 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, and with the power to control the tree, 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, outraged at the theft of its powers, took the form of the Ten-Tails beast and attempted to retrieve it from the world that has now gained the usage of chakra.

By consuming the fruit, Kaguya was able to manifest the Rinnegan, resembling the Shinju's, in the form of a third eye in order to use the Infinite Tsukuyomi. By utilising this technique and God: Nativity of a World of Trees, this will regather all the chakra from 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.
