Gintoki and the gang return to Yoshiwara at Hinowa’s request for the first time in a while. Although Hosen’s death has brought freedom to Yoshiwara, it’s also drawn the renewed interest of those who previously avoided Yoshiwara in fear of Hosen’s power. Yoshiwara is now troubled with an increased crime rate, especially illegal drug dealing. Odd Jobs are asked to capture the man responsible. The man in question is said to go by various names, titles, and even faces. The only clue available is the tattooed spider on his neck.

Gintoki and Tsukuyo infiltrate the Benigumoto, the Red Spiders, to get a lead on the man with the tattooed spider on his neck, but are discovered and quickly surrounded. The two manage to fend for themselves, when the man with the tattooed spider makes a sudden appearance and attacks Gintoki! The man then speaks as if he knows Tsukuyo. Who is this man?!

Tsukuyo falls into the hands of Jiraia, her former master, and is held captive. Meanwhile Gintoki manages to survive the attack thanks to Zenzo, and he learns about Jiraia’s past. During the Amanto attack twenty years ago, Jiraia is said to have killed his own people within the Oniwabanshu, all for the sake of his devotion to the previous shogun. In the end Jiraia himself was the one to be terminated, but he managed to escape. Now his devotion is directed toward his own creation, Tsukuyo. Jiraia’s motive is to eliminate the bond that she has come to rely upon. And he intends to achieve that goal by setting fire to Yoshiwara and burning down everything!

Gintoki strikes down Jiraia and frees Tsukuyo from his twisted web. Chiding Tsukuyo for trying to shoulder every burden herself, Gintoki goes on to say that rather than throw away your life to die beautifully, it’s far better to live and be yourself – even if your life is not a pretty one. And finally, Gintoki expresses his anger toward Jiraia for betraying his own student, despite calling himself a master.

The city of Yoshiwara is making its recovery, though Tsukuyo has shut herself in her room. Hinowa asks Gintoki to help Tsukuyo have some fun for a change. It turns out that Tsukuyo is only pretending to be sleeping in her room, when in reality she is sneaking out to perform her routine patrol. The gang decides to come up with a plan to help Tsukuyo cheer up, even while working.
