From Worm CYOA Wiki
Daimyōjin
From the consumption of the Chakra Fruit you have been given the gift of chakra and its two composite parts, Yin and Yang. The white flames of Shiranui have revealed the secret to its mystical nature and with it came complete understanding of, and the ability to freely and effortlessly manipulate Yang. Yang governs Reality, giving life to Imagination that has none, and is the reason behind almost every jutsu's strength, and how much it affects reality. Almost every jutsu uses a mixture of Yin and Yang, one to give form to imagination and one to bring imagination into reality. With your understanding of Yang, you can now perform things such as amplifying your strength to a ridiculous degree, restoring lost organs, expanding the size of your physical form, and can even be used to greatly amplify the strength of any jutsu you perform. While your mastery of Yang is incredible, its true strength is shown when used in conjunction with its counterpart.
