Bleach: Ill Insomniac

Set after The Thousand-Year Blood War Arc and Yhwach's defeat, Isane Kotetsu, now the Captain of Squad Four of the Thirteen Court Guard Squads continues to adjust to her new duties with her sister Kiyone Kotetsu as her new Lieutenant. While she still thinks of and greatly misses her predecessor Retsu Unohana, she's recently found herself thinking about the man who's humbleness still moved her, even after his death, Jūshirō Ukitake. Even now, ten years later, she still struggles to understand the true depths of her feelings towards the man.
