Shonen Jump has lost another big title with Blue Box coming to an end. At one point it was thought to be the next king of Jump to replace One Piece. Unfortunately One Piece still has many years left to go so that was not in the cards. Box still had a fairly long runtime though and was a fun enough series. I would say that it did start to lose a lot of steam in the second half but that’s just how these things go sometimes. The series was unable to capture the same high levels of energy of the will they/won’t they once the main two were together.
The series follows a boy named Taiki who is really into Badminton and a girl named Chinatsu who is a star Basketball player. They both attend the same high school although Chinatsu is one grade above Taiki’s. He has always had a big crush on her and they see each other a lot as the first two people in the gym every morning. What he didn’t expect was for Chinatsu to move in with him! Her parents will be away for a while and were friends with his parents so they got permission for her to stay so that she could focus on Basketball. Now Taiki has more opportunities to confess but also feels like this is a bad time to do so. It could make her feel uncomfortable…what should he do?
First off I would say that Taiki is absolutely correct here. He may want to confess and everything but to be honest it would be the wrong call. Her parents are counting on this being a relaxing environment for Chinatsu with no distractions. A confession is absolutely selfish here because it puts her in a bad spot if she says no. A confession can’t have any pressure behind it or else the whole thing just won’t feel right. This naturally does lead to a lot of drama though as Chinatsu also likes Taiki but faces the same struggles. They have a hard time getting on the same page and both have other suitors who appear to be interested.
That is much more of a factor for Taiki though. His childhood best friend, Hina, really likes him. She’s not even very subtle about it but Taiki completely sees her as a friend and is oblivious to every flirtatious moment. Unfortunately his best friend Kyo is a professional gaslighter who makes every situation much harder than it has to be. So there’s a lot going on but in a way that’s what makes the first half really intense. It was just really chaotic with a whole lot of players involved.
So lets go with the weaknesses of the series first. One is that the sport matches star to be more off screen as the series goes on. This was never a sports series first and foremost but we still got some really big battles early on like Taiki vs Haryu. By the end of the series we start skipping major portions of matches and even skip all of Nationals itself. You know, the thing that was Taiki’s goal from the start? That was definitely an annoying moment because it would have been so cool. You could easily have cut some chapters from the side characters to make room for that. Chinatsu’s final competitions at least got some screentime even if I would have liked to have seen more.
The other weakness by the end is that the supporting characters were never as interesting. It is pretty much obligatory that you try to pair up all of the side characters at the end but you don’t have a lot of reason to care about them. Not compared to the main two which is where all of the development had gone to anyway. Most of these characters are basically left with rebound options so it’s not like you could say the romances are particularly strong either. It works well enough you could say but it’s why the first half is much better.

As for the art, it’s not bad. It’s definitely not one of the stronger Shonen Jump titles in that area though. In particular there were two characters who looked way too similar and I would constantly mix them up. Yusa and his brother. Now granted, brothers should look alike but they really appeared to be identical at times. The art is still good enough though so I wouldn’t say that I had any serious issues there.
So lets get into the characters. First up we have Taiki and I was really clowning on him throughout the series. He just couldn’t stop catching Ls as most of the drama was his fault. Pushing Chinatsu away while in public because he got scared of what other people would think was something that happened more than once. To be clear, he was doing this because he thought that is what was best for Chinatsu. It still doesn’t make him look much better.
Then he doesn’t handle the Hina situation very well. He actually started out well by initially rejecting her but then Kyo got in his head and Taiki started to hesitate. Taiki initially knew that he only had eyes for Chinatsu and needed to stick with that. Instead Kyo gave him an analogy about coffee and a lot of other crazy stuff. Ultimately Taiki decides to still be close friends with Hina which allows her to try and make another play. That was probably a moment too far for her and he needed to break things off.
It’s extremely hard to be friends with someone who wants you. Especially when they already know that you like someone else. It comes off as really selfish no matter how you slice it. Taiki just lacks in confidence a whole lot and this carried over right to the end of the series. Even in the last chapters he is still acting like that. It’s partially because he is written as the everyman and there is this idea that guys are always going to be a little passive/nervous around the girl. Perhaps it is realistic to a degree but it doesn’t make him a very strong lead. I needed to see more fire out of him instead of learning the same lessons over and over again.
In comparison Chinatsu is the much better character. She basically has to initiate every interaction between them. She never loses sight of her goals or waves in the slightest no matter who approaches her. I also appreciate how defensive she gets when anyone makes fun of Taiki. She is very quick to fire back and that’s the kind of loyalty you like to see. Chinatsu’s a very well rounded character and continues to excel in Basketball/school even outside of the romance. Taiki may be her goal but he isn’t the only part of her world.
Even as someone who was more on team Hina in terms of character, Chinatsu is one of the best parts of the series. There can be no doubt on that. She even gets her own rival later on in the series which was pretty cool. No, not a rival in love but an actual Basketball rival so I really appreciated that. She’ll likely have to continue leading the relationship with Taiki but is more than willing to always put in the effort there.
As for Hina, well I may have liked her a lot but some of her actions are pretty indefensible. She continues to go after Taiki even once he has a girlfriend which is really not cool. I know that some will say it’s all fair game until marriage but that’s not a very healthy outlook. Do you really want a guy that you can steal away so easily? To be direct, you should give up if the person you are interested in is already taken. Nothing good can come from going down that avenue but there are certainly a lot of bad things that can arise.
Once you have moved on, then it’s possible you will find someone else but it will take time. The series presents at least two more options for Hina after Taiki and both feel like they would have just been emotional rebounds. For that reason I am glad that the series didn’t force anything at the end. The door is left open for this to succeed and it’s certainly implied that she will eventually make a choice but at least it wasn’t instant. Hina was taking her time and that’s important.

Her final character arc of realizing that she actually wasn’t over Taiki was actually a really good one. Aside from the misstep of telling him about it, it makes sense that she couldn’t just snap her fingers and be over him. A lot of times in the movies you will see a character just immediately move on when they are rejected but things don’t tend to move that fast. The feelings will take some time to dissipate.
Then we have Kyo who is a particularly weak supporting character. By the time he starts to get more screentime at the end, it is too little, too late. It felt like he was mainly around to just sabotage Taiki for a while there. I want to be clear that he never did this intentionally but has a bad habit of talking way too much and he always just has the wrong takes. The guy is a bit too quiet otherwise and then in his own romance he ends up being passive. Even in the moments that are supposed to make him likable, they never seemed to land. Ultimately I had to give him a thumbs down.
Taiki’s parents were far better as characters. It’s not like they have a big role but they were consistently solid the whole time. They mostly kept a hands off approach but Taiki’s dad would remind him to always do what’s right. Then the mom would always do her best to help out in the background by prepping for events, supporting Taiki, etc. Chinatsu’s parents are much the same way with her father very reasonably not being a fan of the setup once he found out that Taiki liked her. That’s just responsible parenting after all since that opens the door to a lot of tricky situations. He ultimately allows it but I wouldn’t have faulted him even if he had made Chinatsu move out.
Haryu works well as the first rival. In a way he is the older what if version of Taiki. He got to play at a high level and has a good relationship with his girlfriend. Ultimately he chooses not to pursue Badminton past high school though while Taiki wants to keep going. The parallels are fun and he even starts to get spooked about playing Taiki. He worries that losing to him will forever change their dynamic. That was a bit petty since they’re on the same squad and should still be playing each other a whole lot. Not playing because you’re scared will only hinder your growth in the long run.
His girlfriend Karen is a strong character as well. She was always quick on the uptake and wasn’t as oblivious as most of the other characters. She doesn’t get to appear a lot but makes sure to set strong ground rules for her relationship. With Haryu she explains that this can never be an excuse for either of them to fail. It’s a pretty good rule if you ask me although any real character should never be using something like that as an excuse either way.
Hyodo takes over as a new rival for the end of the series. He’s even more powerful than Haryu and is basically unbeatable. He has done that by making Badminton his life. He has pushed aside all other interests and has no interest in getting a girlfriend. You could say he’s the other extreme as a possible Taiki future. It may be possible to surpass him but is the cost really worth it? It just feels like that is not a good idea. The manga never makes Taiki tempted by this approach though which is a good thing.
Then we have Hyodo’s younger brother Yusa who is also super good at the sport. Initially he also believes that it requires a ton of sacrifice but then learns from Taiki that you can still live your complete life along with it. I’d say he just needed some more screentime. His romance with Hina is pretty weak and came too late to really make anything out of it. He would make for a solid character in a sequel story though. There’s nothing really wrong with him but it just feels like the guy came on too late.
Ayame is another character who was a bit of a late inclusion. Not as late as Chinatsu’s next door neighbor who just exists for potential drama but still pretty late. She basically goes through guys really fast which makes a few of the characters worry. What if she sinks her fangs into Taiki?? The story never goes there though and she’s actually a bit of a romantic as she tries to get Hina and Taiki together. Her own romance plot with Kyo is a bit forced though and doesn’t work so well. I appreciated what she added to the dynamic though.
Finally there is Yumeka who is a solid character. She may not have a ton of screentime but I did think that she made for a solid rival to Chinatsu. Her skills were definitely on point and she really managed to keep up. This also worked as a way to give Chinatsu an extra plot that wasn’t directly tied to Taiki. That was a really strong move all the way and also gave a reason for the show to include more Basketball scenes.
While the story beats are all fairly straightforward from the start, this is not a series that is being built around twists. The whole idea here is that Taiki and Chinatsu will get together and you’re just seeing how that happens. In a way you could say that is true for most romance series. It’s all about the adventure, not really about the ending. So you hope against all odds for the underdog to win but know that it will be futile. I just think sometimes the authors accidentally make the backup love interest more interesting than the main one. Hina was just more fun to have around even if you knew that she was doomed. Such is life and the appeal of the doomed romance.
The series still had a light tone throughout and just makes for an easy read. I’d say that it is a series which can really appeal to anyone. The only way you’d dislike this series is if you really just don’t like romance drama. Drama is basically inevitable for any long running romance series though because that’s how they extend the runtime. Blue Box stays pretty safe throughout though with no character making mistakes that I would deem to be irredeemable. Drama goes too far if a character actually cheats or something like that and fortunately we never even approach that point.

Overall, Blue Box is a good series that I can recommend. The romance is well written and the sports dynamic helps to add in a bit of extra flair as well. The ending isn’t the strongest and on a petty note it was kind of annoying that they couldn’t genuinely end by noticing that the gym was like a blue box. Adding a correction that it was actually orange was wholly unnecessary. I’d say the series will especially work well in a binge format so you should just start reading through the series right away. As long as you enjoy romance and/or sports then you will have a good time here.
Overall 6/10
