Second season of .

Two years ago, Mitsuki Kouyama's friend, Eichi Sakurai, moved to America before she could confess her feelings to him. Though she cannot contact him, they made a promise to fulfill their respective dreams: Mitsuki wants to become a professional singer, and Eichi an astronomer. She hopes that one day her music will reach him across the world with a brilliance like that of the full moon. There is just one catch: Mitsuki suffers from throat cancer, which makes her voice quiet and singing strenuous. Her grandmother, who has a hatred of music, insists that Mitsuki undergo surgery to remove the cancer, but she refuses due to the risk of losing her voice. One day, two shinigami—Meroko Yui and Takuto Kira—appear to tell her that she only has one year left to live. This sudden revelation spurs Mitsuki into action, and she decides that with Meroko and Takuto's help, she will become a professional singer in the time she has left. Full Moon wo Sagashite follows the emotional story of Mitsuki and her shinigami friends as they discover what it means to sing—and ultimately, what it means to live. [Written by MAL Rewrite]

Two OVA episodes are bundled as DVDs with each of volumes 6 and 7 of the manga. The first OVA is a prequel story written by the manga's author. Before the beginning of the main story, Rea and Chihiro have already met at a certain place: an outdoor hot-spring bath. The second OVA takes place after the series (effectively episode 14). The Furuya family finds a mysterious young girl hiding under the household temple.

Continuing his masquerade as the deranged lunatic from the Lanling Jin Clan, Wei Wuxian resides in the Cloud Recesses while his former cultivation classmate, Lan Wangji, searches for answers about the demonic severed arm they have in custody. With an overwhelming dark energy emanating from the arm, the two are forced to work together in order to keep it contained. However, the demonic arm is not the only dark force lurking in the region, and as spiritual tensions rise in the mountains of the Gusu Lan Clan, it is up to the two of them to try and restore the natural order. The story of Wei Wuxian's fall from grace continues as more light is shed on his descent into the path of demonic cultivation. The demonic arm only further strains his mischievous spirit. This is the time for him to prove that he has truly broken free from the forbidden path and is not the maniacal sorcerer that everyone remembers him to be. [Written by MAL Rewrite]
