Gintama

We Know It's Best to Finish Yearly Tasks Before the End of the Year, But Then You Put It Off 'til Next Year for a Fresh Start. That's How the End of the Year Goes (4x39)

:

Part 1 - While researching the Anti-Foreigner War, a reporter interviews Nagai, a former reporter from the war called Nagai in order to know about the White Demon's (Gintoki's alter-ego) activities in such time. He chronicles the events from war, explaining how the samurais decided to fight against the aliens. As Nagai is about to talk about the White Demon, he replaces him with the fictional robot Gundam to celebrate the 30th anniversary of the franchise with the same name. Part 2 - Kagura starts going to Kabuki-cho's physical fitness lessons where she meets a kid named Hongou Hiashi, whom she befriends. Suffering from a dangerous disease that weakens his body, Hiashi is absent from various lessons even though he promised Kagura to go to every lesson. During a rainy day, Kagura is the only person to come to the lesson, but Gintoki and her friends decide to join her. Next day, Hiashi returns to another lesson and sees Kagura once again.
