The prequel to the popular yakuza rom-com Fourth Generation Head: Tatsuyuki Oyamato!

A yakuza head finds himself ensnared in the unwavering attentions of a sometimes impetuous but always cunning schemer. If being yakuza doesn't get him killed, his new lover just might!

Akitora chases after Matsumi, who's in possession of his son and Uichi. The long-standing feud between brothers is finally put to an end, and Uichi, who has now accepted he'll never be part of Akitora's family, spends a sad final night with him. Twenty-seven years pass, and the two souls who have grown older, and perhaps wiser, meet again.
