Is It Belief or Convenience Driving Koizumi?


I’m going to be honest when I say that Koizumi is a character I really struggle to understand. I find him interesting in his own way but realistically there’s so much about him that seems inscrutable and I’m not sure if this is a case of information that didn’t make it into the anime adaptation or whether his character is just genuinely hard to read. That said, I’m kind of happy to revisit him and give him some more thought in this post.

Thanks this week to Aria for the wonderful character suggestion. Now there were a number of other great people who suggested characters however again a lot of these characters are ones I just don’t know well enough to do justice to. I do appreciate the suggestions though and I’m keeping them on hand should I get the chance to watch the anime in question. If you have a character you would like to see a post on feel free to suggest them through the survey below.

All About Koizumi

Koizumi is introduced into the story of Haruhi Suzumiya as the ‘mysterious transfer student’ Haruhi has been waiting for. What makes him mysterious is apparently that anyone transferring at that time of year must obviously be mysterious (it is nice that Haruhi’s demands are so easily met sometimes). However, Koizumi is not arriving and grabbing Haruhi’s attention by happenstance and it turns out he’s part of an organisation that is also watching Haruhi, much like Yuki and Mikuru.

Itsuki Koizumi - the mysterious transfer student.

It is hard though to get a read on Koizumi. A lot of what he says comes across as disingenuous and he also is a representative of an organisation which means his actions are not always his own. He makes maddeningly obscure speculations to Kyon at times and maintains a strict routine of not directly influencing Haruhi though he regularly manipulates the situation putting the responsibility on Kyon.

I will admit when watching the anime there were times I genuinely hated Koizumi. And yet there were other times when he came across as logical or sympathetic. Basically, he’s just a complex character and it is really hard to know what is really driving him sometimes because while he calls Haruhi his god, his actions are not always able to be reconciled viewing him as a follower of the divine.

Why Does Koizumi Do Everything
Haruhi Suzumiya Demands?

With the premise being such as it is, Koizumi seems almost obliged to follow along with all of Haruhi’s weird requests and demands. Essentially she is god and his job is to keep her happy. Yet behind the scenes Koizumi seems intent on manipulating that role. For instance, the Summer trip to the mysterious island with the locked room investigation was entirely orchestrated by Koizumi and his organisation in order to ‘entertain’ Haruhi and keep her from getting bored and possibly unmaking reality.

While I can see where they were coming from it seems like a weird relationship with a ‘god’ when you can run around and try to distract them from inadvertently removing you from existence.

This is what happens when you upset Haruhi. Koizumi doesn't want to see that happen.

Likewise, Koizumi works on other characters to have them entertain Haruhi, or at least ensure they don’t upset her too much. Rather than a relationship between a god and a follower it seems more like someone watching over a child prone to tantrums and it seems weird that he doesn’t divert her from some of her sillier endeavours (or at least try to).

How Does Koizumi Represent the
Most Dangerous of By-Standers?

But that’s where I find Koizumi’s character a little bit hard to take. During the filming of Haruhi’s movie she tormented Mikuru and even went as far as drugging her in one instance. When Kyon got angry because of this Koizumi’s aggravating comment was that he thought Kyon was more rational. However, no matter how you want to slice the situation, Haruhi had stepped well and truly over the line (several times in fact) and needed to be pulled up short. That Koizumi is unable or unwilling to and Yuki sits in a similar position means the it becomes Kyon’s responsibility.


Koizumi’s actions really bothered me because he knows that what Haruhi is doing is wrong and actually fairly reprehensible. Where Yuki might get a pass in this situation being not human and reasonably indifferent to the morality in the situation, Koizumi is a human who simply has some power given to him, he thinks, by Haruhi. He understands the full magnitude of what Haruhi is doing and yet he does nothing. Worse than that, he enables to the best of his ability Haruhi’s actions in almost all things to ensure that she doesn’t get upset. So not only does he not condemn her actions, his passive stance actually seems to support her decisions.

Despite Koizumi not having an active role in the situation with Mikuru, he did nothing to prevent it continuing and his actions seemed to endorse the decisions made by Haruhi. His speaking against Kyon’s actions after the fact further cement an understanding that he would have allowed that situation to continue. While overall I find Koizumi a fascinating character I really cannot get behind him in this sequence at all.

What Does Koizumi Actually
Think of Haruhi and of Kyon?

That said, it is difficult to know what Koizumi’s actual feelings are. There are times when it seems like Koizumi is more naturally drawn to Kyon and that he genuinely likes him. There are others when it seems like he sees Kyon as an interesting specimen for observation. Like with a lot of Koizumi’s actions, it is hard to read.


As for Haruhi, Koizumi regularly makes comments along the lines of finding her charming or similar. But it is hard to know whether he believes that himself or whether it is something he is working to convince himself of. Still, even in The Disappearance of Haruhi Suzumiya, Koizumi was the one who ended up by Haruhi’s side so maybe he is naturally drawn to her.

Is Itsuki Koizumi’s Existence
In Itself a Sad One?

I find it very hard to think about Koizumi without wondering what his life would have been like if he’d never awakened as an Esper and never had the knowledge that Haruhi Suzumiya was the one who awakened that power. What kind of person would he be, or would he exist at all, if Haruhi had never wanted to meet an esper. What I do know is that in the context of the anime, Koizumi really has no existence outside of watching over Haruhi and his dealings with Kyon and that in and of itself is a little tragic.


Then again, that is something that you can start to feel for all the characters in the reality of Haruhi Suzumiya as they are seemingly bent and twisted to her will.

If you watched The Melancholy of Haruhi Suzumiya, I’d love to know your thoughts on Itsuki Koizumi and how you feel about his character so leave us a comment below.
