The past of Kenpachi
Before she even became Kenpachi, captain over the infamous division 11, she was a shinigami like any other trying to earn her place in the division.
Akane remembers those early years, when she finished her training and finally became a fullfledged shinigami with a bittersweet feeling. It was then, when she entered Division 11, that she came to know Murakami Shin, captain over her division.
They're meeting was nothing special, and neither was she, except that she was the only one who couldn't wield her zanpakuto. It was something unexpected and unusual, for a shinigami to after knowing its zanpakutos name, not being able to wield it anymore.
