It’s time for a sports/romance hybrid series. The romance eventually starts to overtake the sports aspect but I would say the series does a good job of keeping it mainly balanced at least in this season. The series got good production values and has fun characters so on the whole I would say it’s pretty good. The romance is handled in a serious way as a slow burn which is always the right approach, even if I may not be the biggest fan of the route it decided to go. You can’t win them all after all.
The series starts off by introducing us to Taiki who is a badminton player. He has strong ambitions of becoming the top player and going to Nationals some day. He has a long ways to go for that goal though as his skills just aren’t there yet. He is a first year player so he has time but he wants to make it to the top as soon as possible. Meanwhile he has a crush on the Basketball veteran Chinatsu. She is in her second year and also trying to get her team to Nationals. Can he accomplish his dream and go out with her? Taiki has to play this carefully or he could make the school environment very awkward. There is one thing in his favor though…due to her parents’ work, she will now be living at his place for the foreseeable future.
Naturally living together can make things a bit easier since he will get to talk to her more, but on the other hand it also makes him a lot more self conscious. After all you can think of it as being a selfish move because she is relying on his household right now. So asking her out in this situation may pressure her to say yes, or if she says no, now the whole thing will be even more awkward. So Taiki has to work through his feelings here and I tend to agree with him on staying silent. It just doesn’t feel like the right time. One of Chinatsu’s friends says Taiki should say something since otherwise it is creepy behavior to be secretly liking her.
I get the logic of the counter but don’t really agree with it. There’s nothing inherently bad about it so long as Taiki has no bad intentions. So long as he stays respectful and within boundaries then not saying anything is still the better call. Living together just brings with it way too many complications to have a relationship, although of course this series would be over if nothing happens so you can expect some shenanigans to occur.
Taiki can at times be a little too scared to move forward which causes other problems though. Particularly in the other main romance of the series which is that his childhood friend Hina likes him. Taiki ends up being put in the middle here where he doesn’t really know how to respond to her confession and then that sends a lot of mixed signals over to Chinatsu. So as you can see there are a lot of very messy storylines going on here but it works well because romance is often messy. It’s all about how you respond to all of these sudden developments that shows your true abilities as a character.
I do appreciate that none of the main 3 characters are the jealous types. You don’t see Taiki freaking out when other guys are talking to Chinatsu and vice versa. Not to say they aren’t a little irritated but they don’t suddenly start freaking out or being all sulky. It’s a more mature take which is nice. There are still boundaries of course but if you don’t trust your love interest then the relationship will never work out from the start anyway. So the series definitely gets that one right.
The series also has quite a few sad moments as well. After all, in matters of love there will always be someone who loses out. In this case there are two girls who like Taiki so one will lose and based on the premise and all promotional artwork for the series, you already know who that is gonna be. The series doesn’t pull any punches with this one when the rejection comes through and breaks her heart. Now for the record, once again I have to say that Taiki handled it very well. He didn’t beat around the bush and just offered a complete declination. It may be hard to hear but at least this way he offered up some closure. If he was half hearted or left any room for something to develop then that would have been a mistake.
So while Taiki can sometimes annoy me with how timid and oblivious he can be, this was something he did well. It’s not like there is ever a perfect way to reject someone without leaving them a bit hurt. That’s just going to happen but you can at least do you best to reduce the sting as much as possible. That’s exactly what he did here so I definitely had no qualms with him. Meanwhile the sport moments often don’t go smoothly for the characters either. They definitely get some reality checks and at the end of the day only one player/team can win it all. So statistically the odds of winning are pretty slim.

The series is definitely an emotional rollercoaster with everything going on. At the end of the day I would say it does have an upbeat tone though. The bad things that happen never overwhelm the positive moments. Nobody is falling off a building or getting a rare disease. The drama we get are personal losses and tragedies but nothing that can’t be undone. I think it would actually change the series tone if they went for any storylines that were a bit too dark and depressing. So for me this is the right amount of drama to bring tears to your eyes but by the final episode you know that you’ve had a good time of it.
The animation is pretty solid for the series and helps to elevate the Badminton scenes. The colors are striking and there is a good amount of movement here. It looks better than what you may have expected for a romance series. So I definitely appreciated that. The soundtrack is a little more on the weaker side though. You’re not really going to remember it all that well by the end. It’s not bad by any means but it just feels more like free domain type music. It doesn’t really do much to elevate the series to the next level.
As for the characters, I already spoke about Taiki a bit. Nice kid who means well but I would definitely like to see him act with more confidence. He allows himself to be manipulated too easily by others and tends to really overthink things which gets him into trouble. In order to improve both in romance as well as his sport journey, he will need to get past that and really reach the next level.
Chinatsu does well as the main heroine. She tends to be fairly quiet and keep to herself. Since the series is from Taiki’s point of view, we don’t see her thoughts quite as much. I do appreciate this though because often times it is good to keep to yourself. Chinatsu is always polite and doing what she needs to without being overly expressive. Definitely no issues on that. I’d say if anything her only weakness can be that even when she’s upset she doesn’t say anything which can just lead to resentment. When you’re upset and it’s a possible misunderstanding then you definitely gotta find a way to clear the air there. A big example is definitely when she has a bit of an unspoken fight with Taiki before Nationals that makes things awkward so they aren’t really able to talk and it leaves her a bit distracted. Of course that’s not a valid excuse during a game but still worth noting.
Then we have Hina as the other heroine and the most tragic part here is always when you have the losing heroine accidentally be written to be more fun than the main one. Hina is easily the best character in the series and a real go getter. While everyone else is being too quiet or nervous to say anything, she just marches up to Taiki and confesses. This is absolutely the best way to go about things. It’s a very old fashioned way of thinking to assume that the guy has to make the first move and you just gotta wait your turn. Hina liked him and decided to just go for it.
Immediately she got my respect there and was a very supportive person otherwise. She still didn’t try any underhanded tactics to get an edge and was honorable the whole time. That’s the kind of character you want to have in your corner. Hopefully things go well for her in the future but I’m not rooting for any rebounds here. Ideally she will just continue to do really well in her career and win at Nationals. That would be a fun way to complete her arc.
Kyo is Taiki’s best friend and usually he’s a decent guy but he does have some of the absolute worst takes possible. He spends a whole lot of his screen time constantly gaslighting Taiki and getting him to make the worst mistakes possible. If he didn’t say anything then Taiki would be in less trouble. The guy is mainly just around to confuse the other characters but hasn’t really had any important moments otherwise. You could take him out of the series and for now it wouldn’t really change anything.

Then we have Haryu who is Taiki’s rival. A strong player all around and his romance journey has mainly been rather smooth. His relationship with Karen is a fun one and they are a good example for Taiki to look at and see how things should be done. Haryu does have a rough moment near the end where he starts to fear Taiki and ducks him during all encounters. That’s not how you want the rival to look, but he eventually gets over it. Ultimately the guy is getting older and may have hit his limits in terms of Badminton skills. Meanwhile Taiki still has an opportunity to be the best that there ever was.
Nagisa is a good friend to Chinatsu but doesn’t get much of a role. I’d say she is mainly around because every main character needs at least one friend at their side so the characters can vent a bit. She tends to be rather straight forward which is good and she talks a lot more than Chinatsu. So if the heroine ever needs any help, she knows where to turn. So while Nagisa doesn’t do a whole lot, just being around is still supportive.
Another minor character is Hyodo who is currently the number one Badminton player. The guy is completely invincible and never loses. Anyone who challenges him is very quickly humbled and that’s the kind of ability you like to see. He quiets everyone down with his overwhelming power. Nobody can hope to easily take him down. His character gimmick is that he tends to take everything literally. Not the most interesting gimmick, but again it’s not like he appears all that much.
Then we have Yusa who is being set up to be Taiki’s more serious rival. The guy beat Taiki at first and then Taiki beat him so they are definitely very close in ability. He makes for a fun antagonist here. He’s not a bad guy or anything but of course he is standing in the way of Taiki’s dreams. The guy appears to be the more emotionless sort for now and is very focused on Badminton itself. That kind of drive is always hard to defeat.
Then we have Ayame who joins up near the end. Her ideas of romance are very different from the rest of the characters so she ends up rocking the boat a lot. She will go out with anyone who asks her out and will then usually break up right afterwards when it doesn’t work out. So for that reason she has a ton of ex-boyfriends but most of them end off on a positive note. Naturally she is there to give Taiki unfortunate ideas instead of just letting him trust his heart. She always means well but yeah Ayame has a lot to learn about romance. That much is clear early on and her meddling causes some really serious problems.

Overall, Blue Box was a fun romance title. I appreciate the fact that the series really goes into detail on the different relationship dynamics instead of jus running through it. We know that the series can take up to 2 years in universe because of the grade system so that leaves time for a really good slow burn. Slow burn romances are often the best way to handle things because it allows the characters to fall for each other organically. So I’ll definitely be ready for season 2 and in the meantime you should check this one out. Just watch out if you are a big Hina fan since things often go rough for her and even the opening animations foreshadow this.
Overall 7/10
