The red-light district, Yoshiwara, is suddenly taken over by "Aizen Kou," an incense that has the ability to make anyone fall in love with the first person they see. Having been outlawed for its strong potency, the love drug was thought to have disappeared from the red-light district for good; however, it seems to have found its way back inside Yoshiwara's walls and now has the entire district under its influence.

Unbeknownst to everyone else though, she was already attracted to Gintoki. With those hidden feelings now intensified, Tsukuyo must overcome her afflictions and work with the Yorozuya to return everyone back to normal.

Every 60 years, the heavens conduct a sacred ritual called ETM12. This custom involves selecting worthy Eto-musume—celestial beings representing different animals—to become one of the members of the Chinese zodiac, or Eto-shin. However, since the first ETM12 two thousand years ago, the original batch of Eto-shin reigns with no one being able to replace them. Nyaa-tan is a cat Eto-musume who aspires to become a member of the zodiac in the ongoing ETM12. Fulfilling her ambition requires her to secure 12 seals, one for each Eto-shin. To that end, she must win various types of battles using Sol/Lull—divine energy created by people's positive emotions. This task is not easy however, as her powers as an Eto-musume are far below the abilities of a single Eto-shin. As such, she needs a constant source of energy. But in a chance encounter, Nyaa-tan meets Takeru Amato, a man who has just transferred to the apartment where she is secretly staying. To Nyaa-tan's delight, Takeru discovers that he gives out high quality Sol/Lull—something that sets him apart from most people. With this, the story of Takeru and Nyaa-tan begins. As Takeru supports Nyaa-tan in her dreams, he meets the Eto-shin and begins to uncover a mysterious past. [Written by MAL Rewrite]
