Meiji Tokyo Renka (Simuldub)

On the night of a crimson full moon, Ayazuki Mei, a female high school student, is enticed to enter a magical box by a mysterious magician named Charlie. When she awakens, she finds herself in an unfamiliar park.

During the party at the Rokumeikan, Mei is treated like a suspect by a police officer named Fujita Goro, but Ougai pulls her close and calls Mei his precious fiancée.

Now that it is clear that Mei is a Tamayori who can see ghosts, she decides to help Syunso find the black cat that became a divine spirit. While conducting their search, they get drawn into an investigation of paranormal happenings at a hotel.

Ougai admits to his aunt that Mei is his fiancée and that he intends to formally present her as such at a party being held at the Rokumeikan the following month. Sensing Mei distress at this, Ougai invites her out on a date to Asakusa.

Mei undergoes strict instruction from a geisha named Otoyakko to become a proper lady worthy of being Ougai's fiancée. She struggles desperately to learn how to wear a kimono, how to carry herself, and etiquette.

Mei demands to help Otoyakko with a big party, but is Mei ready to serve Japan's elite?

On a rainy day, Mei and Syunso happen to encounter Kyoka by Shinobazu Pond. Kyoka explains that while in the midst of writing his latest play, Shirayuki, a dragon goddess, suddenly became a divine spirit and escaped from his story and is in the pond.

Mei and Syunso bump into Yakumo while out searching for the black cat. When they find out that Yakumo is going to a café where cats tend to gather, they tag along with him. Along the way, they happen across Kyoka who is arguing with an unfamiliar man.

Ougai is so caught up in writing his novel that Mei begins to worry. Will she get to spend any time with him before the full moon?

Ougai is confronted by his painful past. Can Mei convince him to continue writing, or has it all been for nothing?

After Mei discovers the truth about Syunso's eyes, she is more determined than ever to help him find the black cat!

Mei is faced with a tough decision. Will she stay or will she return to her normal life?
