Lesson 512 is the 512th chapter of the Gintama series.
As the main spacecraft of the Kiheitai crashed, Wakikaoru and other shinobis jumped out of the ship and ran away. Matako, on board, ordered her subordinates to follow them. Though, Takechi was against it, saying that it was a plan of the Oniwabanshuu to divide the Kiheitai's power. Instead, he suggested them fighting with the 7th Division. However, Takasugi had already sent Bansai to there, believing that the Iga Clan would be done soon. While so, he left the spacecraft, intending to end Gintoki's life.
Meanwhile, at the 7th Division's battlefield, the Yorozuya, Kondo, Hijikata and the Shogun were still fighting against members of the Yato Tribe. Abuto turned up, claiming that he had killed Momochi and her shinobis and got her head, which was actually a fake one, and quickly exploded. The real Momochi appeared and attacked the Yato with a gigantic shuriken. The shinobis then came up from the ground, ready to join the battle. Abuto, who had lost his artificial left arm after the explosion, led the other Yatos to continue fighting.
As the battle continued, Momochi led everyone to a bridge and told them to bring the Shogun out of Iga through an escape route. Right when the Yorozuya was crossing halfway of the bridge, she destroyed it, thus separating them. Kondo and Hijikata then joined her in fighting against the Yato, giving the Yorozuya their first and last request: Protect the Shogun.
