Daughter of Lupin

Peaceful days had returned to the family of Hana (Kyoko Fukada), Kazuma (Koji Seto), and An (Nono Obata). Mikumo Hojo (Kanna Hashimoto) had also regained her quiet life after her noisy neighbors moved out. Meanwhile, Etsuko (Shinju Ozawa) was on the verge of collapse due to a lack of treasure. Then, Wataru (Louis Kurihara) offered her a new treasure: "Grace Kelly's beloved Cartier diamond ring." At that moment, Teru Enjoji (Yusuke Onuki) appeared at Hana and Kazuma's apartment. Enjoji asked Hana to pretend to be his fiancée for just one day. Enjoji was scolded by his father, Go (Ichimura Masachika) for not yet marrying his fiancée, Hana. When Hana and Enjoji met with Go, he was pressed for answers about the wedding date and wedding dress. Enjoji was then ordered to steal a ring for Hana that was traditionally given to brides in the Enjoji household. It was the same Cartier diamond ring that the "L family" had been after, the one loved by Grace Kelly.

Hana Mikumo (Kyoko Fukada) has her secret—that they are the "L family"—revealed to her daughter, An (Nono Obata). Meanwhile, Kazuma Sakuraba (Koji Seto), struck down by the deadly blade of Natasha (Rina Ota), a hitman employed by the gang of thieves, is taken to the police hospital. Kazuma is watched over by Norikazu (Masayuki Shinta), Misako (Marcia), their daughter An, and Mikumo Hojo (Kanna Hashimoto), who accompanied him from the crime scene. However, Hana and the others, who are actually still alive and causing a stir in the world by committing robbery and murder, cannot rush to Kazuma's side. All they can do is pray, but their prayers are in vain as Kazuma goes into cardiac arrest. The "L family" is cornered in a desperate situation.

Finally, Mikumo Hana (Fukada Kyoko) and Hojo Mikumo (Hashimoto Kanna) face off! Hana defeats Mikumo and successfully erases her memory of meeting her with a memory-erasing spray. However, she is worried that the "L Family" is still being cornered. The next morning, when Mikumo comes to work, Kazuma (Seto Koji) asks her about what happened the day before, but Mikumo says she doesn't remember. Of course, she's lying. She had prevented the memory-erasing spray from entering her body and maintained her memory.

As Anzu (Obata Nono), the daughter of Mikumo Hana (Fukada Kyoko) and Sakuraba Kazuma (Seto Koji), is on her way to school, Hojo Mikumo (Hashimoto Kanna) suddenly appears before her. Anzu reacts to a picture of Kazuma that Mikumo shows her, exclaiming, "That's Daddy!" Suspecting that Anzu is the child of Kazuma and a daughter of the "L family," Mikumo tries to press her further. However, she manages to escape the predicament thanks to Ladybug No. 3, the bodyguard, sent out by Wataru (Kurihara Rui). An alarm signaling an emergency blares through the "L family" apartment building, but Wataru tries to deceive Hana, Takeru (Watabe Atsuro), and the rest of the family by telling them it was a false alarm. However, Takeru notices that Wataru is acting strangely.
