Kirio Hikifune is a very special kind of shinigamy, her powers are based around a delicate balancing work of being a master cook and a master warrior to combat all threats that may appear in the vicinity of the palace, of course, her role may be less prominent, due to such characteristics, but it's deceptive in nature, not only does she possess the strongest reiatsu control of any shinigamy by far, not only does she have the abilities to literally enhance any kind of food with the most intense soul pressure, with regenerative properties that outclass any healer in the soul society, but also her true power is so strong, that if she were to decide to loosen up, she would completely level down all life in a range so big, it could circumference earth in its entirety, yes, it may be a little exaggeration, but you get the point, the strongest shinigamy, concealing her power in order to preserve stability and only unleashing her pressurised reiatsu, during cooking, at least that's how it should work, most of the time, but something would soon be a little different. One day, as Kirio Hikifune stood awake and walked down the kitchen to prepare a gourmet set for the zero division to be nourished by, readying themselves for the intense trainings and exhibitions ahead, she would feel a shift within her body, a slow, yet noticeable reiatsu movement, a build-up to something that even she didn't expect, it wasn't a curse, it wasn't a display of failure, no, it was something much more nuanced, her true power extent was showing in a very pronounced way as her body slowly began to expand to accommodate her reiatsu, she was becoming so plump in fact, that even her form after the cookout would feel small and insignificant in comparison, thankfully, her uniform didn't bust out on the spot, it was tailored specifically so no matter what size Kirio Hikifune gets, it would be somewhat of a perfect match, even if it was clear that her reiatsu was becoming more and more primal, craving action.
You were a regular at the soul king palace, always attending the quarters of the zero division to keep everything in order, not only because you were the person ichibei trusted the most in how generously he viewed, but also because you proved yourself as a prodigy, posed to be a successor to one of the members in the future. It just so happened that you walked by Kirio Hikifune right at the moment her reiatsu began acting wildly, you were shocked by the sheer extent of her power she was withholding for so long and how her elegant framework transformed into a bulky, yet round shape, still allowing for mobility and combat display, you knew that she could gain massive amounts of weight in seconds, but that was on a completely different level, as if she has tapped into forbidden kido or somehow evolved her zanpakuto, if that was even possible. Deep down, you were shocked, just by looking at her, you were flabbergasted, all this mass, grandeur, mountain of flesh and reiatsu, that buildup was so strong, that you felt the pressure firsthand, it was by far the most intense feeling you've had in years, and that's saying much, considering that you were trained for all kinds of scenario and yet this one was starting to make you feel like a newbie again, but you didn't give up easily, not only standing and watching the entire thing unfold, but also beginning to cast healing kido, trying desperately to remedy the pressure, but Kirio Hikifune decided to stop you midway, speaking up to you in a commanding, yet soft tone.
Do not interrupt the process, you may think it's wrong of me to allow my reiatsu going wildly like this, but trust me, there's only one way to make it quench, prove your worth in the palace once and for all, it's your chance.
Kirio Hikifune challenged you to a duel with her, a display of ancient reiatsu and technique perfection is quite legendary.
Will you survive? Only time decides.
