The Fungiest Wolf

So the first of these "ah-ha" moments was when I realized that Izutsumi really is the best supporting evidence for Laios' point about the good things that wouldn't have happened if Falin hadn't died.

If Falin hadn't been eaten by the dragon, Izutsumi probably would still be a slave. It was because of Shuro and Laios' parties both being in the dungeon to rescue Falin, as well as Marcille's use of ancient magic in the resurrection, that she got the chance to escape. None of that would have been the case if Falin hadn't died. Shuro wouldn't have separated from the group and joined up with his retainers, Marcille wouldn't have revealed her knowledge of ancient magic, and Izutsumi never would have even met any of them. They are only part of her life because of Falin's death.

Though this isn't explicitly pointed out by Laios or Izutsumi in the scene, I do think you can very much feel the presence of it. For one, when Marcille reflects on the journey and how much it made her realize she didn't want to lose everyone, her relationship with Izutsumi is prominent:

It's the main original group at the top and center, but when you read it right to left, it’s Izutsumi and Marcille who might catch your eye first. And it's specifically Marcille and Izutsumi's relationship on display here, not just Izutsumi's presence in the group in general.

Also, after Laios' statement about how none of their adventure would have happened without Falin dying, it is Izutsumi who gets the final word:

Izutsumi is also the one here who is the most forward-facing. Chilchuck is trying to correct Laios, Senshi is focused on the immediate future, and Izutsumi is talking about her new goal.

And I want to talk about that goal in general as well, because it’s also interesting how it comes up. In that moment, everyone is trying to remind Marcille of her less destructive desires - to eat food, to share it with them, and to meet Chilchuck's family. All of which are previously established, existing desires. When prompted by Chilchuck to join in, however, Izutsumi offers something new:

That's interesting, isn't it? It's kind of funny, of course, to see her rambling on about a completely new thing, her own personal motive, in the middle of everyone working together to reach out to Marcille. Izutsumi doesn't even know who Yaad is! But at the same time, it’s kind of meaningful. Amidst the focus on desires that everyone already had, she adds a completely new one to the mix. It’s even the final bridge that lets Laios reach Marcille.

It is, in fact, even an idea that comes back later to help out another lord of the dungeon. The idea of finding new goals and feeling new desires... this is exactly how Kabru reaches out to Mithrun, after the Winged Lion is gone

So yeah, Izutsumi's presence here, both in what she's actively choosing to say as well as what she represents of the consequences of Falin's death, supports the story's ideas of moving forward. Of accepting the past, and finding new reasons to live.

Which is all really good, and that alone works pretty well as an answer to what Izutsumi's role in the story is.

But oh, oh. There's more. Something I realized after having thought of all this, because I still couldn't let go of the feeling that there was still something I was missing.

And as I reviewed the things I loved about Izutsumi - her sometimes unhealthy ways of coping with trauma, her struggles with isolation, her skill with fighting, her selfishness contrasted with the ways she grows to care for and protect the group, her perpetually guarded nature, born from the seeming impossibility of ever fitting in or finding a safe place to just be herself - I realized something.

Izutsumi...

is a foil to Falin.

Where Falin copes with isolation and trauma by being eternally caring and struggling to say no to people, Izutsumi copes by constantly saying no to everything she can. Falin is often considered selfless, but does have selfish desires that she can’t easily express until a moment of crisis. Izutsumi is delightfully selfish, but chooses to stick by her friends when they need her. They are both transformed, against their will, into partly monstrous hybrids, and they both will have to live with that - there is no undoing what has been done to them.

Falin anchors the group in the past. Izutsumi pulls them towards the future. Neither would find freedom without the other - it is Falin's death that leads to Izutsumi joining the party, and likewise, it is Izutsumi who inspires the realization of how they can save Falin.

And Falin is her future, as much as Izutsumi is Falin's. Both learn to be a little more like each other, even though they never meet. Falin gets a little more selfish. Izutsumi gets a little more willing to bend.

In this context, I feel like I have finally started to understand just how important Izutsumi is to the story. She is a proof that they cannot just go back, and she is a clawed, happy-to-scratch-anyone-who-pisses-her-off reminder, at that. In any conversation about what the group wishes would have happened with Falin, she cannot be ignored or brushed aside.
