Can somebody explain me what does Yin or Yang chakra does ?
I heard it's related with the black things you get by getting the Rinnegan, Izanagi, Naruto's jesus technic, and the Mizukage's mirage jutsu.
Yin-chakra is chakra which obtained the characteristics of Yō(Yang), in the manga it's called Yōton. Yōton is vitalizing. There are different applications for Yōton though, but Hagromo Ōtsutsuki has used Yōton to breath life into the nine parts of Jūbi. Narutos seal on his right hand has also a connection to Yōton.
Yang-chakra obtained the characteristics of In(Yang). In the manga it's called Inton. Inton is used for genjutsu, it governs the power of imagination. Sasukes seal has also a connection to Inton.
Then, there is Inyōton, the Yin-Yang release. By combining both powers a new chakra-element will be created. Gudōdama, Banbutsu Sōzō and Izanagi base on that Seishitsuhenka. Madara Uchiha said that he has created Shiro Zetsu due to Inyōton too.
