Yakuza Fianc: Raise wa Tanin ga Ii Vol. 2

WOULD YOU LOOK AT THAT, WE'RE THROWING OFF SPARKS

The problems have compounded between Yoshino and Kirishima as their underworld love begins to blossom. Kirishima is charming, handsome, and funny...but his hair trigger for violence and his twisted declarations of masochistic love put Yoshino off-balance. And now a local yakuza princess has disappeared, and Kirishima has to stick with her for her protection! Yoshino knows she's got to find that missing girl as soon as possible so that she can be alone again! But the only person she can ask for help is...Kirishima himself?
