She began working at the Cous Coussier restaurant as the Greeed awaken, worried for her brother's well being when she eventually learns of the incident he was in. To prevent her from worrying, Eiji sends her a text message using Shingo's cell phone stating Shingo is on an undercover mission and won't be home for a long time. However, Hina, finds the two of them and hugs Ankh, thinking that he is still her brother. However, Ankh attempts to harm Hina, but Eiji threatens to dispose of the OOO Driver in the river should Ankh do so. He changes his mind, and Eiji takes her to the Cous Coussier restaurant. Eiji later tells her the truth, while promising to save her brother. Eventually, realizing his reason of looking after Ankh, Hina convinces Eiji to work at the Cous Coussier so she can care for her brother's body. She often uses her super strength to keep Ankh in line if he begins to treat her brother's body poorly or when he does something she does not agree with. Ankh does not like her and the two often argue, with only Hina's bizarre strength allowing her to win arguments. One day Eiji and Ankh talk about recent chain of events before Hina arrives with Ankh grabbing her by the throat. However, Ankh finds that he can no longer bring himself to harm Hina. Hina eventually comes to realize she has been relying on Eiji's need to help to an unhealthy degree, and is taking steps to ensure Eiji does not blindly sacrifice himself for other people's sakes. After much contemplation, Hina also realizes she has come to care for Ankh, and wants both Ankh and Eiji, as well as her brother, to make it out of the Medal conflict alive.

The Kuzu Yummies appear and attack in the restaurant as Hina evacuates the customers. Later, she arrived where Eiji and Ankh is as the Future Rider, Michal Minato explains the situation that he was having of being a Rider. At night time, the possessed Michal planned to steal some Core Medals from Ankh, but he was one step ahead from he as they regained more Core Medals from Michal. However, Poseidon forms it's own body from Michal as he overpowers OOO. On the next day, Kousei tells Eiji that he is the only one that can fight Poseidon as the Birth Drivers were needed to be repaired from the previous battle. Before Eiji confronts Poseidon, Michal was curious as to why Eiji was not worrying as he gives Michal his pants telling him that to keep on living for the next day. After Poseidon was defeated, they wave good-bye to Kamen Rider Aqua as he returns to his timeline, but she notices that Ankh is also gone.
