Five stars for story, um. Maybe like 2.5 for Yen Press's translation. The scans are translated much better, which I think is kind of rare in the wide world of manga. But I still buy the volumes to support Yana Toboso, so here we are.
I know it seems to be a popular thing not to like the curry arc, but it's actually one of my favorites. ... of course I don't have an arc I don't like, but I think the brilliant bits of this arc are the subtle things below the surface. At first glance it seems a bit frivolous – Ciel being a brat about his bizarre house guests and the whole thing culminating in a contest of who makes the best curry, of all things. But look a little closer and you've got a really great character study going on. Soma and Agni are really obviously foils of Ciel and Sebastian. Soma is what Ciel would be without the added trauma in his early life (that gets addressed in chapter 19), and Sebastian, despite being one hell of a butler, will never be as good as Agni. Ciel also recognizes the part of himself in Soma and bestows mercy on him; Sebastian's in the middle of completely ripping apart the poor kid's psyche and Ciel steps in to stop it, which shows that Ciel is capable of a compassion that Sebastian, as a demon, never will be.
What I think is great about Soma and Agni's existence is that instead of competing with them – with the exception of the fencing scene, where Ciel is defeated for being a cheat – Ciel and Sebastian more or less just accept them. Sebastian sees that Agni is superior and yields to that fact; unlike a human character, who might end up at odds with him. He even says that Agni has a power he will never be able to defeat: the loyalty and love for his master that has given him the power of god. This is something that Sebastian and Ciel, their contract being formed from evil and hatred, will never be able to overcome. It's all really interesting and unexpected stuff, which I love.
I also don't think this is racist at all. In fact I think from a historical standpoint, Ciel's acceptance of Soma and Agni is almost too progressive for the time. (Having read literature written in the Victorian era, some of the stuff that comes up about the East is kind of shocking to me in its blatant narrow-mindedness.) But then again, given what Ciel's been through, I think stuff like race and class matters less to him; he's mad at Soma for being a mooch, not for being Indian. Of course Sebastian doesn't care because he's not even human. I like that approach to the subject matter, honestly. The Victorians did have a fascination with India and all that stuff about the Anglo-Indians really happened. Yana Toboso does her research and I'm always delighted with what she does with it in the context of the story.
