Konpeito saved Orihime. Konpeito saved Rukia from execution. Konpeito saved Soul Society from Aizen. Konpeito...!

That aside, it's strange to say this considering we are nearing the end of the series, but I feel I have yet to fully understand Shinozaki.
Perhaps it's because we did not fully return to the moment of his presumed accident, seemingly due to wandering into their lab as an innocent child before requiring human repository magic to 'put him back together'*, but I am struggling to fit Yuuyake's wish in the present with Shinozaki. It should be equivalent to the same inner desires that we have seen expressed by other characters as the enchantment is being reapplied, but it isn't clicking in the same way.
It's a fantastic moment for Yuuyake to see her overcome her struggles with magic and even serves as a solid gag due to the incorporation of machines into the final application. Plus, in the process we get to see a flash of many of the major and even minor characters throughout the series here. But I'm not putting two and two together. What should have been an intense emotional revelatory moment, in my mind at least, was reflected more as a gag and a very simply presented earnest wish: a wish that Shinozaki has not embodied throughout this story.
Yuuyake has. After her grandmother's passing, she spends her days minding her grandmother's workshop and cafe, never growing close to any other magical folk. She fixes and fixes and fixes; all she does is repair inanimate objects that can be restored if ever they are damaged. These things cannot leave her, and once perfected they are optimized until they cannot deviate into a dangerous, unexpected, uncertain territory (in theory, but not in practice). She avoids using magic, an uncontrollable variable, possibly in relation to Shinozaki's accident. She is perfectly safe in that insular bubble, detached and unable to be harmed by the loss of any other.
In short, this revelation captures an underlying desire that drives Yuuyake's behaviour and history. She lost her parents, she lost Shinozaki, she lost her grandmother. She can't bear to risk being responsible for losing anyone else.
Shinozaki on the other hand? Where have we seen a similar impulse or drive? The closest element, off the top of my head, is his hopes prior to the festival for Yuuyake to cheer up. He's nice. He's kind. He's thoughtful at times. But I don't ever recall him ever expressing anything resembling this, nor any of his behaviour hinting at this. Every other major repository has had plenty of scenes and build-up to illustrate how they are ultimately kindred spirits.
I don't know. There's something on the page I am missing. A blind spot. Or maybe I'm shooting myself in the foot with these expectations. Either way, I can't help but feel a tad disappointed until the next chapter inevitably arrives.
