Yakuza Fiancé: Raise wa Tanin ga Ii

Yakuza boss Renji Somei arranges for his granddaughter Yoshino to marry Kirishima Miyama, the seemingly kind grandson of another mobster.

Yoshino feels vexed by Kirishima's obsessive affection. Later, they learn that the daughter of a Miyama family business associate has gone missing.

Renji visits Tokyo for a dinner with other yakuza bosses. Yoshino meets up with the Somei clan member who raised her, as well as her childhood friend.

Yoshino intervenes as Kirishima and Shoma engage in a tense standoff over her. Later, she worries that Kirishima has gotten bored of her again.

Kirishima goes with Yoshino to Yokohama to meet her cousin from Kyoto. As they enjoy their time together, Yoshino gets a call from her school.

Kirishima runs into his ex-girlfriend Nao, who has returned from overseas. Later, he and Yoshino head to Osaka, where they encounter Shoma.

While touring a college campus in Osaka, Yoshino approaches Nao, who tells her about Kirishima's past. That night, Ozu makes a demand of Nao.

After eavesdropping on Ozu's group, Yoshino comes up with a plan and informs Kirishima, who leaves Nao in Shoma's care and hurries to Yoshino's side.

Yoshino witnesses Ozu arguing with one of the gangsters but is soon spotted. As Kirishima deals with the other criminals, a formidable foe appears.

Following the ordeal in the park, Kirishima and Yoshino coolly confront Ozu and demand that he clear up Nao's scandals and stay away from her.
