Sports and Romance in Blue Box

Welcome, weebs, to Animated Observations

I feel like this is cheating since I briefly talked about Blue Box in a secondary findings post a while back, but I actually managed to catch up all the way, which as of the writing of this post is chapter 65.

For those who are still uninitiated with this manga, allow me a brief summary. Taiki is a freshman badminton player who has found himself crushing on his basketball player senpai Chinatsu because they see each other every morning before their respective practices in the gym. Upon learning that she will be moving abroad and thus will not be able to compete in her final year of basketball, Taiki works up the courage to tell her to do what she wants, and not what is dictated by her parents. Chinatsu then ambushes him with the fact that she actually is not moving, and is instead staying with a family friend. Except, that family friend is actually Taiki’s mom, and so the two begin to live together.

Whereas most authors would take that setup, let harem shenanigans ensue, and then promptly cash their checks, Koji Miura has taken a different approach. Well, I say different, but in reality, it is much more standard fair, just done really well.

Romantic comedy and sports is a weird cross-section that I have never taken much time to explore. Like, there have always been elements of it in other shows, with one character centering the sports activities because they themselves are on a team (see Lovely Complex) but I honestly cannot say much for shows where the sports and the budding romantic relationships between those players take center stage. Luckily. Blue Box manages to capitalize on this fusion in a way that, while definitely nothing innovative, is great in execution.

What strikes me the most about this series right off the bat is just how unassuming it tends to be. Taiki, for all his teenage gawking at Chinatsu, never puts his own feelings above hers, and Chinatsu is much the same way. The two very obviously develop feelings for each other, and yet they do basically nothing aside from exchanging some witty dialogue and a few awkward glances. However, where a lot of series would chalk this up to just teenage awkwardness, Blue Box subverts this trope with its focus on sports. The whole reason Chinatsu ends up staying in the first place is so she can finish school and her last two years of basketball, and part of why the two even find each other attractive to begin with is their willingness to dedicate themselves to their sports. Where characters in other high school romances get lost in their aloofness and unwillingness to admit their feelings, Taiki, Chinatsu, and to a lesser extent Hina, are much more focused on accomplishing their own goals.

I was initially going to put the word sports in huge, sarcastic quotations in the title of this post because my impression of this series is that sports were just a mechanism for having these characters meet at specific times and locations and miss each other at different times and locations. That is wrong, though. The matches and competitions that our main characters take part in are exciting and well drawn. Still, sports also serve an important thematic role, one that teaches the ideas of patience, hard work, and dedication, things that are necessary for a healthy romantic relationship. We even see this reiterated in Haryuu’s relationship with his girlfriend Karen later on in the story, which is seemingly built on the idea of putting their own pursuits ahead of their relationship, a sentiment that has become increasingly popular with younger generations.

Despite the fact that I just complimented two of them, If I could point to anywhere this has maybe been lackluster so far, it would probably be in its side characters. Kyou is probably the most immediate example of this, as his role for most of the story thus far has been one of an observer. Rarely does he intervene in any conflict, and oftentimes he is just a mediator between Taiki and Hina. Recently chapters have given him a bit more development, and even hinted at his own romantic feelings for Hina, but he still feels like an afterthought in most cases. I feel like it would have been more interesting to get a bit of backstory on the relationship between Taiki and Chinatsu’s mother at this point, but at the same time, the series is also not over yet, so we’ll have to wait and see.

So, yeah, go read it. Why are you still here?

You can tell I really mean it because I even went through the trouble of avoiding major spoilers (partly because I am also incredibly tired this week, but that is less important). Have you read this series already, though? What are your thoughts? Let me know down in the comments.
