Yakuza Fiancé: Raise wa Tanin ga Ii

Yoshino grew up as the yakuza princess of the Osaka Somei crime family. Everyone left her alone due to her sharp gaze and mobster ties. But when her grandfather signs a truce with the Tokyo-based Miyama crime family, she’s offered for betrothal to the Miyama leader’s grandson, Kirishima. At first, Kirishima seems amiable and polite–but when he shows his dark side, he proves to be more disturbing than any gangster Yoshino has ever met. This engagement is sure to be a wild ride for a tough yakuza princess and her twisted yakuza prince!
