Grand Blue

Iori Kitahara moves to the coastal town of Izu for his freshman year at its university, taking residence above Grand Blue, his uncle's scuba diving shop. Iori has high hopes and dreams about having the ideal college experience, but when he enters the shop he is sucked into the alcoholic activities of the carefree members of the Diving Club who frequent the place. Persuaded by upperclassmen Shinji Tokita and Ryuujirou Kotobuki, Iori reluctantly joins their bizarre party. His cousin Chisa Kotegawa later walks in and catches him in the act, earning Iori her utter disdain.

Based on Kenji Inoue and Kimitake Yoshioka's popular comedy manga, Grand Blue follows Iori's misadventures with his eccentric new friends as he strives to realize his ideal college dream, while also learning how to scuba dive.

Just try watching it, you will absolutely love it. The first season was of only 12 epis and it felt so short. That's why i started reading the manga and i am caught up to it now. I watched Grand Blue as a seasonal when it was releasing. It was pretty underrated that time. But until lockdown, it got some amount of popularity and now in 2025 its quite famous. It was even surprising for me that the manga was on top 10 highest rated mangas in MAL. It actually deserves it, as it is goated.

Iori and Kouhei gotta be the best duo of all ... time. It was always hilarious to watch both of them. And comedy is not the only thing Grand Blue is good at. It has some most heart touching moments both in the manga and the anime( quite less in anime as it has Season 1 only).
Some moments were heartbreaking too :(. Iykyk.
Well then, Have a great day ahead. See ya.

Mixed Feelings

Is the peak of comedy in praise of a masculinity that is years behind the times?

Ignoring the tendentiousness of my introductory question, I had some expectations with this series, seeing that it is no less than number ELEVEN in the manga charts here (to give you an idea, it is above series like Kingdom, Punpun, Houseki No Kuni, 20th Century Boys and Nana) and also that a couple of acquaintances had recommended it to me. So I said, well, I'm not in the mood for dense and dramatic stuff, and it's 12 chapters long, so if I like it, I'll pick up the manga. Why ... not give it a chance?

You can see that the people I know aren't immune to adoring things that outside the weeb spectrum wouldn't get half as much praise as they do. And mind you, not every seinen has to be a drama about the human existence and suffering, we need stuff that's easy to digest in the art we consume. The point is that my relationship with this series expresses something very obvious: comedy is subjective, and making it is very difficult.

Although I don't think it's fair to detract from that aspect of the series, because in some moments it's the only thing that saves it from being nothingness itself. It generated this strange thing that only Japanese comedy can generate in me: at times there were well-executed jokes that made me laugh out loud and at other times the degrading sex jokes employed made me think that it's not that hard to realize why Japan has had a declining birth rate for years.

I guess if I can sum up the comedy of this show in two words, it would be: bro humor. I don't know if that term exists but I'm going to coin it. In and of itself the fact that they go for hyper masculine rhetoric behind several of the gags presented in this series is not a problem (shit, JoJo knew how to do it very well). But the fact that a large percentage of the ridiculous and excessive debacle that this series handles is entirely between groups of men, excluding a lot of the female characters from the comedy, doesn't do it for me. And if that wasn't enough, let's sexualize the girls without their consent, because that's hilarious without a doubt! It also doesn't help the constant screaming that is this series, and although that's not something that usually bothers me in anime, here there is an excess of testosterone being expelled so intensely that I'm sure my estrogens formed new antibodies to the point that my ovaries were about to pop out of my body, pierce the screen and hit some of the male protagonists.

This gives me the perfect excuse to talk about the characters, because with the null plot that this has, I don't even think it's worth to talk about it. They're not the worst characters I've ever seen, but they lack... something, I don't know, I feel that none of them have a strong enough personality to impose themselves in a strong way in front of the whole sequence of intense situations that happen to them. Neither of them have much depth and in general their way of being is reduced to a specific gag, and if there is conflict, it only matters on a micro level in a certain situation. There are a couple of funny interactions (Azusa believing that Iori is bi for example, or the two muscular boys which in general I found to be nice enough, although except for the hair color they are the same character twice) but not much more than that. The reduction of characters to a specific gag gets particularly awful with Nanaka (because this isn't going to be the peak of Japanese comedy without gratuitous incest!), Iori and Kohei's classmates (I suffered through their segments a lot) and especially between Chisa and Iori's interactions.

Chisa especially is a character that frustrates me, because she's another eminence of female characters being victims of reductionist male writing. Usually she would be the character that stupid girls like me would have to identify with, and I suppose if it were another type of series she would work for me. But the only thing I can conclude about her is that there's no reason for her to surround herself with those people, being that she's constantly exasperated, and that she's was concieved as a character to have a shy girl that even though she CLEARLY doesn't want to be in compromising situations, the story puts her in them anyway because it's hilarious to see girls in sexual scenes, especially if they don't want to do it! Not to mention the fact that she and Iori are cousins and for half of this season there are jokes about them being a couple, sorry people but nothing in the way they interact says “cousins” (how are you going to make comments about your cousin's ass?) even if this is an attempt to appeal to that fetish, they are failing miserably in the process. Something that even struck me about Chisa, is that more than once they use other characters to tell us how she feels. Weird af if you ask me. At least Asuza is cool and Aina has a bit more range in terms of her personality and for some reason the fact that they called her “Hekabo” always made me laugh, I don't know if it's because I imagined her with that bizarre makeup or what the hell.

Considering what I just said, this series made me conclude something interesting about comedy anime set in our world. Even though it takes place in a realistic setting, with characters that you could run into in real life, doing things that the average Japanese person would do, the situations portrayed at times are so absurd that they border on the far-fetched. And as much as you can tell me “it's a comedy, you can not take it so seriously” yes, that's true, but there are limits to how far I can let humor go to modify the ways of human interaction in such an extreme way. Especially if I feel that the characters don't do enough to make the lack of realism employed at least enjoyable to watch (I mean, GOD, WHAT PERSON WITH A MINIMUM OF RESPECT FOR THEMSELVES LETS HIS FRIENDS INTERRUPT A SEXUAL ENCOUNTER AND STILL BE FRIENDS WITH THOSE PEOPLE? not to mention that they claim not to have a partner and then live crying, anyway, I insist, then they wonder why their birth rates are declining).

You can see that the escapist and ludic theme reigns supreme in this anime, even if there's a lot of humiliation and extreme interactions involved, since at the end of the day it's an “ode to youth” and living a dream. In any case what I see here is a fourth-rate wet dream that would probably come from the mind of someone whose only contact with the world and with art is comedy anime, because (although maybe I'm giving people too much credit) I find it hard to think that someone who is not used to anime could conceive of this as “peak comedy”. Maybe I didn't turn my brain off enough and I overestimate too much what I consume, but clearly my brain isn't going to turn off if I watch humor that degrades women!

Maybe I'm asking too much of anime, who knows. Maybe a little more diving would have made this more digestible for me, at least I expected that when it started. Maybe less sexualization would make me a little nicer to what I see, but then again maybe my western brain likes to talk and complain about the things weebs like. If the manga is anything like this, I don't think I'll read it, and its position on the charts will continue to baffle me, though if I decide to leave my dignity behind for a while maybe I'll watch season 2.

Anyway, I think I got a crueler review than I thought, despite my complaints it's not the most offensive or degrading comedy I've seen and if you're better at turning off your brain than I am, there's a chance you'll enjoy it. The animation delivers and despite everything, it's funny at times even for pretentious sourpusses like me. But I think I'm better off watching Nozaki-kun, at least there the gender roles are not so strongly delimited.

I went into this show with a lot of expectations, thanks to all the hype. People kept saying, "Oh, it's one of the funniest anime out there," and honestly, I feel like I missed the joke. Don’t get me wrong, I can appreciate over-the-top humor and ridiculous situations, but this? It just felt like it was trying too hard most of the time. Like that one friend at a party who keeps telling the same joke, hoping someone will laugh, but you’re just sitting there sipping your drink, waiting for it to end.

Let’s talk about Iori, the main guy. The dude has zero backbone. I ... get it, he’s supposed to be this everyman thrown into absurd situations, but come on, bro, stand up for yourself! Watching him constantly get dragged into drinking contests or stripped down to his underwear while he just awkwardly smiles or panics… it wasn’t funny after the third time. It was like watching a train wreck in slow motion, except you don’t even care about the train.

And then there’s the comedy. Look, I’m not some stoic guy who doesn’t laugh—I wanted to laugh. I really did. But half the jokes were just loud yelling, dudes getting naked (again), and overused gags that felt stale after two episodes. Like, I get that naked guys are funny in certain contexts, but when it’s 80% of your humor? Eh, it gets old fast. My face was so blank most of the time, I could’ve been mistaken for a statue.

The diving part? Oh yeah, remember how this anime is supposedly about diving? Because the show sure doesn’t. Every now and then, they throw in these beautiful underwater scenes that made me think, “Okay, maybe now it’s going to get serious and meaningful,” but nah. It’s like the anime itself forgot it had a plot and decided to double down on its frat-boy antics instead.

And can we please talk about the lack of romance? I’m not saying every anime needs to have some grand love story, but they teased something between Iori and Chisa just enough to keep you hoping for something—a confession, a real connection, maybe even just a moment where they’re not awkwardly arguing. But nope. Nothing. It was like ordering a pizza and getting an empty box. A little disappointing, you know?

All that said, I won’t lie—there were a few moments where I cracked a smile. Like when Kohei gets into his otaku rants or when the older guys act like total lunatics. But those were rare, and they weren’t enough to carry the whole show.

So yeah, I’d give Grand Blue a solid 5/10. It’s not the worst thing I’ve ever watched, but it’s definitely not something I’d recommend unless you’re really into slapstick humor and drunken chaos. Maybe the manga is better? I dunno. Either way, it’s one of those shows I’ll probably forget about in a few months.
