"Oooku" Episode 05 delves deeper into the intricate labyrinth of identities and explores how they influence the characters' interactions. This episode places a strong emphasis on identity, particularly gender identity, and examines the difficulties associated with being forced into societal roles that do not align with one's true self.

The central figure of this narrative is Iemitsu, also known as Chie. Although born a woman, Chie is compelled by the machinations of Kasuga and others in the palace to assume a male role. This forced identity shift takes an emotional toll, and the resulting turmoil significantly affects Chie's interactions with those around her. The extent of her frustration becomes evident when she insists that Arikoto and the other men dress in cross-dressing attire for entertainment, mirroring her own predicament.

The episode marks a significant shift in Chie's story when Arikoto accepts her as a woman, not just as the Shogun. However, Chie's relationship with Arikoto raises concerns, as she subjects him to a cyclical pattern of punishment and reward. This dynamic echoes the traumatic experiences she herself has endured.

Chie's admiration for Murasaki from "The Tale of Genji" adds an ironic layer to her narrative, as there are parallels between her story and Murasaki's. Both characters are forced to conform to the desires of others.

Another character grappling with identity in this episode is Arikoto, who struggles with an existential crisis. He, too, is thrust into an unfamiliar role that threatens his self-worth, which he only regains by helping Chie. The episode ends with a hint that Kasuga may disapprove of Arikoto's influence on Chie.
