I think this might be my favorite chapter of Umihashi so far, and that means a lot since I've personally helped work on nearly all the chapters and got an in-depth feel for them over the time I've dedicated to each since I joined the team for chapter 11.
We never see the movie Tracing Blood, so we have to take the characters' impressions of it as narrative fact. The idea that it's a story about the (twisted, slasher) relationship between a woman and her grandmother she's not actually related to is extremely interesting when juxtaposed against our two main characters. It feels like an arrangement Kai could reach inside himself to pull out his own personal experiences and feelings for. Even if those feelings end up in a zombie horror film, and therefore exaggerated and uncomfortable and maybe even silly, I have a sense that he could convey his feelings with an authenticity through this medium-- especially since Umiko herself was playing the zombie grandma.
(An aside, but making her a zombie doesn't feel diminishing because it's been established that Kai has a personal passion for this genre; if anything, he's elevating her in his personal art. However I haven't considered the deeper implications of his past with the zombie genre and what it could means that he's folded Umiko into that genre; I also haven't given thought yet to what it means to the greater context of the manga's story to portray an alive character as an undead one; I've only considered the surface level implications so far).
What I love the most about this chapter though, is how the talent agency guy says Kai handled the story with "cynicism and affection," and we get further evidence of this when Kai is talking with his mom. If his mom decided to talk frankly about the divorce after seeing the film, it means something about Umiko's circumstances "as a mother" "as a housewife" resonated directly with Kai's mom. But Umiko didn't write Tracing Blood; Kai cares about Umiko with such a deep affection, but with a cynicism that allows him clarity of thought and feeling, so much so that he was able to portray what he saw in and about her without even fully understanding it, but in a way that someone else could recognize and connect with.
To put it another way, Kai learned more about his mom and about Umiko, by portraying Umiko earnestly and then listening to someone who connected with that portrayal. Umiko's quotes juxtaposed with Kai's mom's words really nails down Kai's breakthrough regarding the two characters without Umiko even being present.
It's complicated though. Umiko is still struggling to express her own story. She harbors her own frustrations entirely separate to and fully unaware of Kai's transforming relationship with his own art. It feels like we are really deep in the meat of this drama.
Thanks everyone for following along with Swaggoneers' english releases of Umihashi. Please look forward to more as we continue towards this manga's conclusion.
