After another month of lackluster encyclopedia sales, Muranishi's job is on the line. But just when he starts making money, his life falls apart.

Muranishi and Toshi move onto selling porn magazines, starting their own bookstore chain in Hokkaido. But their success attracts unwanted attention.

After living on the lam in Tokyo, Muranishi and Toshi are arrested in Sapporo. Once they get out, they reunite with Kawada with a new goal: video.

Furuya tells the Sapphire team that Ikezawa and Takei are working together. Muranishi recruits a Poseidon actress for their next video.

Muranishi takes his crew to Hawaii for an ambitious make-or-break shoot with Allison, a famous American porn star. Toshi goes to Furuya for help.

Facing a 370-year prison term, Muranishi 100 million yen to make bail. While Toshi and Kawada struggle to raise funds, Kaoru demands to help out.

Back in Japan, the Showa era is ending and Kaoru Kuroki has become a sensation. Sapphire and Poseidon are cranking out videos, but a crackdown looms.
