Yoto is a complete and total pervert, but he doesn’t think that’s a problem. What bothers him is that every time he tries to bluff his way through one of his indiscretions, his inability to drop his façade digs him in even deeper. Tsukiko also has an issue and wants to get rid of her habit of blurting out whatever she happens to be thinking. So when they both learn about a statue of a cat that can take away a single personality trait that you want to get rid of, they’re both eager to try it.
A perverted youth with dubious intentions finds himself next to a girl seeking a more mature air about her. Their prayers to the Stony cat atop the hill are answered, but they both soon regret their actions.
Yoto attempts to get his facade back by taking Azuki Azusa out on a commoner's date, to show her that her princess facade isn't all it's cracked up to be and therefore relinquishing that which Koto holds dear.
After the arcade incident, Azuki has confined herself to her bedroom. Yoto, searching for answers, discovers a painful part of her past that still affects her today.
Yoto finally confronts Tsukiko over the way she treats her sister, but he is not prepare to hear what she has to say about it.
Azusa has finally made her way to Okinawa with Morii and Moriya in tow, but instead of enjoying herself, she's glued to her phone. Meanwhile, Yoto's house is gone and he only has Tsukiko for support.

As the typhoon continues to grow worse, the house begins to flood and Tsukiko and Yoto discover a hidden room.
While discussing plans for the school festival, a little girl claims to be Ponta’s little sister, Emi.
Y?to, still perturbed by Emi’s wishes and Tsukiko’s cold behavior, meets Ponta, who informs him that his rabbit has gone missing.
As Yoto's wish cancellation only took a partial effect, Azusa becomes enamored by Y?to, much to Mai's chagrin.
The cat god can play cruel tricks, as it sends Tsukiko and Yoto back in time. Tsukiko meets familiar faces from her past.
Yoto and Tsukiko's time in the past is not done, and there's one more thing that must be done before they return to the present.
