Consumed by negative emotions, Douman is transformed into a giant demon. He now possesses within his body Antenmaru, a demon sealed away over a millennium ago by the desperate efforts of the Ketsuno and Shirino clans. As Seimei is about to be killed by Antenmaru, Gintoki stands before him with his aura-charged wooden sword. Gintoki charges his sword with everybody's energy including Douman's in order to overwhelm Antenmaru and bring a sunny day. After Antenmaru is destroyed, Gintoki leaves so that Ketsuno Ana will not know about the fight. However, he requests Gedomaru to make Ketsuno Ana to give him her autograph. Douman appears alive and ends up having a childish fight against Seimei. As Odd Jobs leave, Ketsuno Ana expresses her thanks to Gintoki in her weather forecast.
Gintoki fights Antenmaru merely as a fan of Christel. With his bokuto powered by Gedomaru and Seimei’s familiar he cuts Antenmaru’s arm off and deflects his attacks. As he strikes Douman remembers how he and Seimei were friends with the promise of getting stronger they made. Held back by these Gintoki strikes his head. Douman temporarily comes to his senses and begs that Seimei defeat him to fulfil their promise.
Antenmaru grabs and throws him. All of the Shirino Onmyouji cast their spells to power Gintoki’s bokuto up, Douman entrusts Seimei with protecting Edo before Seimei casts his spell to power Gintoki’s bokuto up. Meanwhile the rain has become a typhoon yet Christel continues her weather report.
The spells continue to power his bokuto up as Gintoki prepares a decisive blow, the demon regenerates his arm and attacks, while Christel continues. Gintoki strikes back with a blow that pierces Antenmaru and flies off into the sky causing it to clear.
With the feud over both the Shirino and Ketsuno clans work together to rebuild their households and Seimei talks about how they have to work together.
Gintoki asks Gedomaru to get Christel’s autograph before he leaves in exchange while she tells him that she’ll never forget him. Before he leaves Douman reveals that he’s still alive and that he and his clan have prepared a thank you gift, but Seimei appears and one ups him.
And the arc ends with members of the Ketsuno and Shirino clan having stayed behind to record Christel’s report. They hear her indirectly thank Gintoki through her horoscope.
The ending theme is shown in full with highlights from the arc in typical Gintama fashion. In the trailer for the movie, part of the theme song by DOES can be heard.
“Bakuchi Dancer” by DOES.
The Yorozuya talk about the movie and the Benizakura arc which Gintoki has changed for him to have straight hair. Kagura takes a go and the conversation shifts to Katsura.
