ok so
In general, I would say that the story is competent in all the "right" ways. If somebody pitched this to me and I ran a shonen imprint, I'd probably take it. It has a ton of good things going for it, from a high concept, to a high-stakes plot, to an interesting battle system, and a generally good structure. However, I'd REALLY be side-eyeing the execution, and I don't only mean this because of the... assistance.
Like pretty much everyone here has said, the idea of calligraphy fights is cool. Having someone who battles purely by writing instead of the usual superhuman senses and kool epik fighting skillz is great in concept. I also think that the way these battles are held is interesting. Someone else would've just had Kaito write 'assault rifle' for 30 chapters and be done with it, but bro gave S P E C T A C L E. Correct me if I'm wrong, but this really feels like it was a manga idea/script before a novella.
However, and this will be a pattern, what could've been an amazing, fun skillset is severely weighed down by how STUPID OP THE POWERS ARE. You mentioned that a weakness could be running out of ink but... come on now. The only time where this became an issue was near the end so he could have an epik moment with ink blood. It was legitimately cool, but it did feel like a 'because this is a climax and cool things are supposed to happen' moment rather than a genuine grievance. The battle system really could use fleshing out, especially regarding actual limitations so the protagonist doesn't feel like a demigod stepping on ants, because frankly, that's how most of the story felt.
There's also the 'why does everyone let him write reality-bending kanji' elephant in the room which goes entirely unaddressed. You kind of had Yuki defend him a few times, but there are several others where he seems to write pretty complex kanji while surrounded by mooks. And nobody... shoots him? Not even a stone throw? Nothing?
I think the plot, structure and sequence of events adds to that 'high concept shonen' feel. It does what it should and it works because of it. Execution notwithstanding, I do think that it hits despite how, frankly, I've seen this story thousands of times. If nothing else, this is a textbook case of "cliches work for a reason". Even though I've seen this story thousands of times, it kept me entertained and invested.
Something I do want to note is that you did go out of your way to add themes that not only enhance but fundamentally build the story. The only reason why the plot exists is because two people with very similar backgrounds took radically different paths that ended up clashing. I'd mentioned it in passing before, but the 'we're not so different you and I' bit unironically works very well. Again, the issue is the EXECUTION.
Leaving aside how Kage is a disappointingly weak villain despite a strong foundation, the entirety of his motivations were info dumped in an extremely unsubtle flashback and even more unsubtle dialogue. No joke, I've read books meant for kindergarteners with more subtext than this. To be honest with you, even though I liked the idea, the execution was so poor that it unironically ruined the climax for me. It reminds me of the times I specifically look for 7/10 shonen I can consoom only to cringe from the inside out when the villain says some shit like IF I'M BETTER THAN YOU, WHY DO YOU HAVE EVERYTHING I WANT??? while it's raining and he's talking about the power of friendship.
The Shadow Corp in general is, again, functional, but they're very, extremely evil corpo(TM) coded. Along with Mr. Shadow, I would say that this is by far the weakest aspect of the story. It works, but it detracts. Just like with Mr. Kage, this is easily solvable with better execution.
Since I've brought it up, that's pretty much my main grievance aside from the AssIstance. The whole work feels very rushed which brings down every individual aspect which, again, could be great. The "first arc" works fine, but the pace just goes off the rails after that. It almost feels as though you're crossing off a checklist. As a result, the characters themselves don't have time to breathe.
Now, I will say, Kaito was actually pretty good. I would say that he's one of the better protagonists I've seen in this contest. I've already praised how he works so well with the themes and how his past compliments present events rather than just be tragic backstory(TM), but he as a character is pretty likable. I can appreciate a character who is competent and kind but not necessarily "the bravest" or someone with the bestest willpower evar. He's just a guy who's trying to do his best (with demigod powers). I also like how the text never says this outright, but he's actually pretty smart, and this is reflected on the way he engages in battles.
Unfortunately, the same cannot be said for basically any other character. Yuki was pretty cool at first, but she's just kind of... there? I legitimately couldn't tell you anything about her aside from noncommital adjectives that could apply to anyone. At least Mr. Shadow had a chuuni villain quality to him, but she's just Girl. Why? Because the story's rushed and feels like a checklist, and she is Girl Companion. Still, I'd be lying if I said that I wasn't sad with her ultimate fate, but this is more so due to me liking Kaito and feeling bad for him.
So... it's a cool concept piece. Pretty nice first draft. Fun, dynamic structure. It desperately needs to be expanded upon.
Then again, more frivolous souls might say that those above would rather go for high concepts and smooth down the rough edges along the way. Heaven knows the medium is full of stories like that.
Due to the aforementioned reasons, I also really liked the ending. I think that even with my grievances and Mr. Shadow chuuning all over the room, you really stuck the landing. I especially like that, not only does it open the possibility for more (honestly I'm half convinced this is a prequel), but it offers an alternative where it's not humans OR yokai, but both. In general, the way you set up Kaito and Mr. Shadow really gives the story a gentle feeling, which is, to me, why the message landed so well. I think that's also why so many people enjoyed it so much (aside from, let's face it, sakuga). It's details like these that elevate a familiar story to something that can stay with the reader long after it's done. Anyone can slap tropes together and write something fun enough, but it takes an extra something to write with genuine empathy, and I think you've managed to do it. 
I'll definitely be looking forward to reading more from you in the future.
