 * It states that Naruto was able to perfectly demonstrate the power of Yin-Yang Release after obtaining Hagoromo's power. The panel this caption goes with is the one in which Naruto is trying to explain to Sakura how he created Kakashi's new left eye, meaning he used Yin-Yang Release to create it, not just Yang Release to "regenerate" it.
 * The Uchiha tended to inherit Yin Release power, while the Senju tended to inherit Yang Release power.
