Everyone gather together gladly to help Nagi search for Hayate. The girls try to figure out the mystery: the Black Camellia, the woman—Dolly, the accident 13 years ago, and Hayate’s strange behavior. After Izumi and Hinagiku mention that Hayate got stabbed the previous night, Nagi comes to a conclusion. Ruri appears and Nagi asks her to bring her Dolly’s ring; Hayate’s life depends on it. Nagi orders Klaus to deliver her mother's wedding ring over immediately then lends it to her friend, Ruka Suirenji, so Hayate will notice the ring on Ruka’s TV interview. Ruri found Dolly's ring and receive an email to meet at the Starside Hotel. Tonight at Ruka’s concert, Nagi’s friends go there to enjoy the show. Hayate and Yukiji arrive at the hotel; Hayate goes into Ruka’s dressing room and found a note written by Nagi informing him the ring is at the wedding hall. In the wedding hall, Nagi reveals the Black Camellia is a sword that exchanges a person’s soul and what happened 13 years ago, and thus Hayate is now Shin Hayek—Nagi’s father! Shin sat down with Nagi and talk about Yukariko. Dolly shows up with a captured Ruri and demands the Black Camellia, but Nagi and Shin explain that her beloved king died 13 years ago and Hayate is inside the clock now. Shin demands his ring back that signifies his and Yukariko’s eternal love. While Yukiji beats up the thieves, chaos rises above her and Maria cause by Dolly.
