The Akudarma trio travel to 17th century Edo in order to find Kasuga no Tsubone, who established the Ooku. They see that the rattle she’s using to calm Takechiyo (who would later become Tokugawa Iemitsu) has the Dynamond on it. They Time Bokan to a period where Takechiyo is older, and Kasuga no Tsubone tells them that she’ll give the rattle to the woman who becomes Iemitsu’s wife. And then Tokio and Calen show up and they battle to see who can become Iemitsu’s bride.
