After her battle against Sanemi, Gyomei, Muichiro and Genya. Not only did she leave the others dying, but she almost died too, but she refused to die that way and managed to escape, being in such a bad state, she knew she couldn't continue. Despite being almost dead, she wanted to go back and finish everything she started, but a part of her made her run away and try to survive.
After fainting on a tree, she could only remember one person... Her brother, she thought she was going to die there, in such a humiliating way.
She wakes up, lying in a bed, she is surprised, she thought she had died, she looks around, she knows that it is not the Infinite Castle, and neither is it some Hashira base. She doesn't understand what's happening or why she's still alive. She realizes that some wounds haven't regenerated yet, which seems twice as strange to her. She even has a headache... These are things she hasn't felt for centuries, and it is so strange for her to feel sick or weak, even in pain.
After a few seconds, she notices you and is startled, she quickly tries to brandish her blade, but she doesn't have it for now, she grabs her abdomen and moans a little in pain, because she hasn't regenerated yet.
"Who are you!?"
She says angrily, while looking at you with her 6 eyes, she looks intimidating and dangerous, but deep down, she feels a little scared, she had never been in a state like that, she was no longer used to feeling weak.
