Retsu Unohana Fucks Ukitake (Bleach XXX)
Captain Retsu Unohana and Ukitake Taicho having sex.

Retsu Unohana hentai is one of the most fascinating and important characters in the Bleach universe. Initially, she’s introduced as the captain of the 4th Division, responsible for healing and medicine. With her calm, gentle personality and soft voice, she appears to be the most harmless and benevolent figure in the Gotei 13 (the shinigami military organization).
However, as the story progresses, her true identity is revealed, which completely changes the perception of her.
The True Identity and the Title of Kenpachi
Unohana is not just a healer. She is the first person to hold the title of Kenpachi. This name is given to the strongest and most bloodthirsty shinigami of each generation. Her original name is Yachiru Unohana, and she was a brutal criminal, the first to found the 11th Division of the Gotei 13, a division focused on pure combat.
She was the main inspiration for the current Kenpachi, Zaraki Kenpachi, who, without knowing it, defeated her in a fight when he was a child. The confrontation was so traumatic for Zaraki that he suppressed his memories and unconsciously limited his own power so he could have a “fun” fight against someone as strong as Unohana again.
Her Role in the Story
Unohana became the captain of the 4th Division to suppress her murderous nature and use her combat and healing abilities for good. In the Thousand-Year Blood War arc, she returns to fight Zaraki in a brutal battle, with the sole purpose of helping him recover his full power.
In short, Retsu Unohana is the personification of duality in Bleach: a seemingly gentle, healing figure who actually hides a dark past and an overwhelming combat power. She is one of the strongest and most crucial characters for the development of the plot and other characters.
