Midora's second Death Note

Midora's second Death Note is the Death Note belonging to the Shinigami Midora that she tossed into the Human World. Midora later gives the note to Ryuk who does the same.

Plot
Midora was fascinated by Ryuk's adventures in the human world with the human Light Yagami. So fascinated that she wishes to go into the human world herself and possess her own human.

Midora obtained this second Death Note by bribing the Shinigami King with human apples, a delicacy introduced to the Shinigami Realm by Ryuk. Midora dropped the Death Note into the human world and it landed in Japan (whether this is a coincidence or intentional is unknown). The Death Note was obtained by an unnamed human, gender and age unknown. This human assumed the role of Kira, committing mercy killings rather than killing criminals.

The Death Note user, known only as C-Kira, was later talked down by Near (now known as L), and wrote their own name in the Death Note. Midora returns to the Shinigami Realm and offers the notebook to Ryuk, who accepts. He searches for a human for four years and chooses Minoru Tanaka, leading into The a-Kira Story. The ultimate fate of this notebook is unknown, but it can be assumed Ryuk took it back to the Shinigami Realm with him.
