Igarashi's comments:
When we have our meetings, the password will be: "The good times ended with Yamabe..."
The original plan for the Lily arc was a bittersweet ending where Yurika always had feelings for Aoyama and still does to this day. But around the time I was drafting it, there was
a grooming scandal in the manga industry. I had to reflect on if it was wrong of me to glamorize this sort of relationship in a modern manga. I've never viewed age-gap relationships very positively to begin with, and wasn't sure I could proceed. By the time I'd written chapter 17 I couldn't stand making Yurika come across as a decent person. After a lot of thought I consulted my editor, who understood my perspective and helped change to the current ending. That's what happened behind the scenes.
Stories in the S genre often depict beautiful age-gap relationships and I was inspired to try my hand at it too. But as the times change so does culture. After weighing my respect for S against my moral values, I decided I lacked the capability to beautify such a relationship and gave up on the idea. It's nothing more than me being stubborn about not wanting to portray it sweetly, even bittersweetly. I still very much enjoy reading age-gap relationships from other authors. I simply didn't want to feel so conflicted toward my own writing.
I'm known for being stubborn, and as someone who works in the entertainment industry I'm always cursing my stubbornness for working against myself. But after hearing about that scandal it brought to mind students I used to teach in cram school, and hurt to think of it that way. I couldn't separate my personal feelings from the issue and couldn't bring myself to profit off glorifying that sort of relationship... So the story took a 180 turn to its ending. I deeply apologize to Aoyama and Yurika... With all that said, don't you think the writing was crazy good!? Wasn't the artwork on another level!?
It's hard to discuss the arc without addressing Igarashi's circumstances, but I think it plays well into the meta-narrative of the manga. Arisaku is a love letter to the past, carrying Class S into the future, without shying from the ugly nature of such a transformation. Sayori and Mizuki represented a tragic parting commonly seen in Class S up until boxcutting their way into a toxic yuri epilogue that wasn't shamed for being so. It was raw in the way romanticized feelings tend to be once dragged into reality, but reciprocal and fulfilling. That isn't the case here.
In days of yore this age gap relationship with an abrupt separation might have been treated bittersweetly. But in a modern lens it's a much uglier thing. Aoyama wasn't left meekly pining but abused and confused, frustrations twisting her into something she hated while Yurika suffered nothing. It did seem at first Yurika's perspective could change the tone in hindsight but plans changed, though Igarashi seems to have always had a bittersweet ending in mind. And with reflection she chose to make Yurika irredeemable.
As another stubborn creative, this was a challenging chapter to translate. It didn't feel right using such harsh language in an otherwise delicate manga but at the same time it was Aoyama's voice. Her roughness overcompensating for the pitiful softness welling up as Yurika threatened to give her another chance. Ultimately Yurika was and is a fucking child, irresponsible and careless and undeserving of her position looking after others, both then and now. I think we've all had that realization as part of growing up, that the adults around us aren't much more than kids in suits (especially with the world today). It leaves you aimless and wondering if you'll be any better. I hope it wasn't as traumatizing for you as it was for Aoyama, but unfortunately that's the truth for many. I respect Igarashi for not wanting to romanticize it even if it makes the manga that much bleaker.
At the start of chapter 18
Igarashi deliberately gave Aoyama no shadow to show she wasn't part of the same dimension as the lily field. At the end
she has a faint shadow in the desolate field her old self is buried. You could interpret that as Aoyama starting to live again, finding new presence in the world after ridding herself of the past. Or the opposite, that she's become less attached to this world and a more spiritual presence. You never see this Aoyama's face in any of those panels. It's an expression of uncertainty in who she is. But in a way, her facial expressions would color our impression of who she's become. And as the purely unadorned ユリ she's left without meaning in both senses.
The rest of the symbolism at the end is more straightforward. Plants only flower once mature; flowers are their reproductive structure after all. Aoyama wishes they could have stayed in immature innocence. Pollen is how plants reproduce, and once Aoyama is stained by it there's no going back. The smell of lilies masks the rotten nature of what happened yet she can't let herself be seduced by it again. It's all buried in one grave.
If there's any hope to my analysis (I keep trying to turn this around into something less depressing sounding I swear) it's that ancient symbolism of lilies sprouting from graves. Aoyama is buried and a new Aoyama blooms. She's not as awful as Yurika, she recognizes her wrongs. We likely won't see it but I trust she has a brighter future in store.
I don't remember if we talked about it here, but with all the flower symbolism it has been talked about and on my mind: in a sense the passing down of Class S tradition is a form of reproduction. A reproduction via thought that still molds others in your likeness. If Kasumi and Haruyo are the descendants of Class S they're the descendants of Aoyama as well. While it was a painful experience for her, it still led to brighter times. And that encapsulates the relationship between Class S and Yuri. We can only hope Yamabe wasn't really the end of the good times.
