Chapter 291: Wind Is Coming to the Seireitei
Even with the explicit offer on the table, Hinamori kept shaking her head.
"No, no, it's fine -- too many sweets isn't good for keeping in shape, so..."
Girls tended to hold firm on that kind of thing, which was reasonable enough. But looking at Hinamori's actual figure while she said it gave Matsushita Yusuke a moment of internal pause.
Soifon had been exactly the same way before the pregnancy. Why did it always seem to be people who absolutely did not need to worry about it who worried about it the most?
Matsumoto Rangiku, for example, appeared to operate on an entirely different philosophical framework -- food and drink in whatever quantities, no apparent consideration given to the question.
Maybe the things you didn't naturally have were the things you felt most compelled to protect.
The original story had apparently included some remark about Matsumoto finding her own figure a source of physical inconvenience, specifically around back pain. Which, from a certain perspective, did qualify as a problem. Just not quite the category of problem that generated much sympathy.
Hinamori was still working through a list of polite refusals, visibly wrestling with herself. Matsushita Yusuke gave an easy laugh and quietly ordered extra matcha dango without making an announcement about it.
"Do you want the glazed kind or plain?"
He added, in a tone that was almost a reminder:
"This place does pretty good work. I put in a reservation in advance, so we can order now and they'll make it fresh." A brief pause. "The texture is something else when it's warm."
Gulp.
The swallow was audible. Hinamori had pulled her lower lip in on one side, and her small tooth was just visible, and she was making a very specific sound that communicated the internal struggle in real time.
Visibly torn.
"I, I--"
Her hands knotted together in front of her. Her gaze went sideways, then the other way, then back. Then, with the expression of someone abandoning a position they had been defending with great effort, she slowly exhaled.
"If -- if I absolutely have to choose -- glazed! Sweet bean glaze! Completely covered!"
When you suppress something too hard for too long, it tends to come back at full force at the first available opportunity. Matsushita Yusuke watched the Squad 5 vice-captain abandon her principles with a face that had gone very slightly bright, and felt genuinely fond about it.
He wasn't sure exactly when it had happened.
Maybe it came with getting older.
But lately he kept finding something quietly satisfying about the specific moment a person gave in and crossed their own line. Was that a character flaw? Probably. But here he was.
"Yours. Take it."
The tri-color dango, still steaming, passed into her hands. Hinamori made a sound of genuine, complete happiness.
"Thank you so much, Captain Matsushita!"
It wasn't a complicated dish by any measure. Essentially seasoned rice cake, at its core.
But that was exactly why the freshly made version hit the way it did.
Hinamori worked through a piece with the expression of someone entirely satisfied with a decision they had made, rubbing the side of her face lightly and making small sounds of contentment as she went.
"Vice-Captain Hinamori -- do you not get to eat out much normally?"
"There's almost never any free time to wander around, so even this kind of thing -- by the time I get to it, it's usually already gone cold." She nodded with the cheerful energy of someone confirming a fact rather than complaining about it. "Eating it while it's warm really is a completely different experience!"
Every squad had its own version of demanding. The specific texture of that demand varied, but nobody escaped it.
Because of his ongoing private contact with Aizen, Matsushita Yusuke had a reasonable working knowledge of Squad 5's internal operations. What he had seen suggested that Hinamori, as the one actually managing the administrative side of it, was a genuinely capable political operator in the most useful sense of that term.
He was thinking this when she nodded briskly at his observation, and then her expression shifted into something more purposeful, like something had occurred to her.
"Which is exactly why we should walk faster! If the dango cools down before we get there, Vice-Captain Soifon won't be happy about it!"
Cold rice cake was not significantly better than no rice cake. Even reheated, the specific quality that came from fresh steaming -- the fragrance, the softness -- diminished considerably.
Matsushita Yusuke knew this, and gave a small, knowing smile.
He raised what was in his right hand.
"Don't worry. I have my own solution."
Around his right hand, a visible current of blue light was spiraling slowly -- reiatsu made tangible, flowing in a contained pattern until it settled and spread in a slow, even coat across the bag in his hand. The reiatsu solidified as it spread, taking on a gel-like consistency, and the entire package became enclosed in a translucent blue glow.
Hinamori, watching this happen, produced an expression of mild surprise.
Hm? What is...?
She was not without Kido knowledge herself -- her own proficiency was well above average, and she could run complex techniques when she needed to. So the assessment came quickly enough.
There were elements of Bakudo in the structure -- it looked like something that interrupted the exchange between the interior and the exterior air. But there was a distinctly layered quality to it. Something closer to a containment field than a standard barrier.
Specialized knowledge, and still couldn't fully decode it in a short look.
Hinamori's expression stayed uncertain. Matsushita Yusuke caught it, raised an eyebrow slightly, and then gave a small laugh as though something had just come back to him.
"My apologies. I don't think I ever formally submitted the theoretical write-up to the Academy."
But since it had come up.
"Vice-Captain Hinamori -- have you heard of the theory I proposed?"
He raised his left hand and gestured somewhat vaguely, mouth half-open as though he was about to say something specific -- and then the words stalled in his throat and didn't quite resolve into a clear form.
Which was a little embarrassing, considering the material was his.
Fortunately, Hinamori's reaction picked up the slack before the moment went flat. Her expression went from curious to genuinely lit up.
"I know it! The one Captain Matsushita proposed -- it's the Kido Fusion Theory, right?!"
She was visibly excited in a way that suggested this was the kind of topic she had strong feelings about.
"I heard about it during my Academy years. Honestly -- the first time I encountered it I was completely stunned."
That was probably overstating it, but the theory itself was genuinely unconventional.
"You argued that the vast majority of Kido techniques share a fundamental underlying commonality -- so with sufficient mastery and the ability to maintain split focus, it should be possible to fuse Kido techniques together mid-use!"
Alongside his work as Squad 11's captain, Matsushita Yusuke had, over the years, accepted various invitations to contribute to the broader institutional conversation. Guest lectures at the Shin'o Academy. A number of papers and journals on Kido technique.
Those things were numerous enough, and sufficiently scattered across time, that his brain had developed a fairly efficient system for letting them drift into the background.
Full recall was a lot of work. Easier not to bother.
...Right, that was it.
Ironically, the person who had written the theory was being outpaced in his description of it by someone who had read it as a student.
There was a reason for that.
"Why did you stop developing the argument? I used to follow every journal you put out on it. I kept thinking someone like you was actually going to change the direction Kido was heading in!"
Watching Hinamori with her barely contained anticipation, Matsushita Yusuke made a quiet, understanding sound and said with a smile:
"You were following those? I appreciate it. As for why it stalled--" A brief, slightly rueful laugh. "It turned out to be something the established way of thinking couldn't absorb."
Simple enough as an explanation.
Kido had a long history. Centuries of development had built a substantial and deeply entrenched information structure around it. Higher-tier Kido incantations weren't just restricted in use -- even knowledge of them was withheld from lower-level practitioners. Access was controlled at every layer.
The knowledge monopoly was one dimension of it. The more fundamental issue was the management of capability itself.
The Kido Corps existed as an institution specifically organized around Kido as its core function. That kind of body represented vested interests in the clearest sense.
Matsushita Yusuke could advocate for what he believed in and put his ideas into writing. He had every right to.
But what fell within acceptable boundaries and what didn't -- that was a line that moved depending on who was drawing it. Who proposed a change? Who supported it? Who opposed it? Who answered for the consequences if something went wrong?
Without clear accountability at each step, nothing got pushed through to completion. Getting stuck at certain points was simply what happened.
The institutional friction in those situations was consistent and predictable.
The Seireitei was a specific kind of place. Even someone with a captain's seat and a captain's strength had to know which moments required absorbing the resistance quietly rather than pushing through it. Yamamoto understood this principle and had tacitly endorsed it as the operating logic of the institution.
Matsushita Yusuke had not always seen the value in that kind of patience. But time had done its work, and at some point he had stopped fighting it and simply adjusted.
He thought occasionally about a particular story -- a noble who had been too visible about their ambitions, made themselves a target for others in the institution, and ended up pushed outside the system entirely, forced into a position that required the Gotei 13 to deal with them directly.
Wanting to change Soul Society was not inherently wrong.
What made it complicated -- genuinely, frustratingly complicated -- was time.
Just time.
Even against resistance, even against people actively working to obstruct things -- that was ultimately a single obstacle in a longer process. Spiritual beings at sufficient strength could run for a thousand years. An obstacle that wouldn't move today could simply be left to develop at its own pace. Patience applied at the right scale bent everything eventually.
That was something both he and Aizen had understood through their own means over the course of these years.
The concept of feudal structure, the avoidance of personal force as a primary tool -- those weren't positions taken out of genuine philosophical commitment. Soul Society simply had its own way of reshaping the people who operated within it, forcing them to internalize its rules whether they agreed with those rules or not.
Honestly -- given enough time, neither he nor Aizen would have objected to working through those channels. The slow approach was the correct approach.
But people were not purely rational instruments.
Aizen couldn't tolerate existing within a structure that placed someone above him. What he wanted was the position at the top, and the view from it, and the completeness of that.
Matsushita Yusuke's reason was considerably simpler.
He didn't have time.
He had arrived with roughly a hundred years to work with. Developing his own strength had taken two or three decades. Building relationships, accumulating the people and position he needed -- another four or five decades on top of that.
More than half the available time, gone.
Reforming Soul Society from within in preparation for everything that was coming -- looked at honestly, the odds had never been in his favor from that angle.
So joining Aizen had been, at its foundation, a form of self-preservation.
The thought circled and settled, and Matsushita Yusuke came back to the present. He looked at Hinamori beside him, eyes still bright, clearly waiting for a real answer to the question she had asked.
He felt slightly at a loss.
How exactly was he supposed to say any of that out loud? He turned it over for a moment, found nothing satisfying, and arrived at the obvious answer.
"Some things you don't understand at the time, and then later you do."
He had heard that line said to him before, in circumstances where he had found it genuinely frustrating. Saying it now to someone else, he felt the full weight of what it meant to be on the other side of it.
Hinamori produced the appropriate expression -- slightly skeptical, slightly resigned -- and Matsushita Yusuke couldn't help laughing.
There had been plenty of situations like this over the years. Things that stalled, plans that hit walls, improvements that got stuck in institutional friction and never quite resolved.
He had eventually stopped fighting the friction. No grand vision had been lost in that. He had never been working toward anything that ambitious to begin with.
But even with all of that -- he found his thoughts moving forward, toward what was coming.
The oldest structures were always the most entangled. Sometimes external force was what was needed to shake loose what wouldn't move on its own.
Soul Society needed change.
And the person who would be the catalyst for that -- the singular figure capable of stirring up all three worlds at once -- was right now growing, steadily, step by step, approaching the form Matsushita Yusuke had always known was coming.
He had been about to say something further when a gust of wind came through and hit them both directly, prompting a small startled sound from Hinamori.
Dango with dust on it was not the same experience.
"Let's move faster, Vice-Captain Hinamori."
Matsushita Yusuke stepped ahead of her, took a long stride forward.
"Wind is coming to the Seireitei."
