However, after befriending Mitsuo Yanagisawa, he decides to move on and begin a new life at law school in Tokyo. But just as he is beginning to adjust to his college life, the beautiful Kouko Kaga dramatically barges into Banri's life, and their chance meeting marks the beginning of an unforgettable year. After having a glimpse of college life, Banri learns that he is in a new place and a new world—a place where he can be reborn, have new friends, fall in love, make mistakes, and grow. And as he begins to discover who he was, the path he has chosen leads him towards a blindingly bright life that he will never want to forget.

The race to obtain the lost Ainu gold is nearing its peak, as even more formidable ex-prisoners are set on keeping their tattooed skins intact. Saichi The Immortal Sugimoto and Asirpa can finally move forward together, but Asirpa's time with Kiroranke and Ogata Hyakunosuke has slightly altered her ambition and strengthened her determination. As their party leaves the Russian territory, they gain a peculiar follower. Meanwhile, Toshizou Hijikata's crew makes major moves to get invaluable skins, falling into the poisonous trap of a dangerous convict. Although each group possesses a strong advantage over the others, even First Lieutenant Tokushirou Tsurumi—the most powerful and ruthless contender—cannot advance without Asirpa's help. However, his ominous plans for when they will inevitably meet remain a mystery.
