The Yin Release is used to create form and the Yang release is used to breathe life into form. The Yin release stands for spiritual energy while as the Yang release stands for physical energy. Today I have made a list of characters who could use both Yin and Yang Release.
10. Hashirama Senju-
We begin the list with Hashirama Senju. He was a reincarnate of Asura Ōtsutsuki. Being a Senju provided him with extremely strong physical and spiritual life force. Because of this particular reason, he was able to use both Yin and Yang Release. Also, most of the Senju were able to use Yang Release as they were the descendants of Asura.
9. Obito Uchiha-
Obito became the jinchūriki of the ten tails during the war. He possessed the the truth seeking balls, which enabled him to use both Yin and Yang Release.
