Hinamori Amu encountered the conspiracy of the transfer student Hoshina Kanoko, and was falsely accused of catalyzing the darkening of the guardian egg. Zuozi used the power of the ancient purple moon to distort the facts, alienate Yameng and her fellow guardians, and even turned her against her lover Bianli Weishi. In the midst of betrayal and separation, Yameng, with the help of Ji Dou and Gebei, discovered that the power of Ziyue was actually the corrupted power of hope. In the end, she realizes that true hope comes from within rather than the approval of others, and evolves into the form of a Hope Keeper, revealing the truth about Kanoko's twisted desires and manipulation. After experiencing the collapse of trust and rebuilding himself, Yameng not only saved his controlled companions, but also found his own path of growth.
