Grand Blue Season 2

Three months have passed since Iori Kitahara began living above Grand Blue, his uncle's scuba diving shop, and joined his university's Diving Club. Alongside the other members, he has spent his days drinking and recklessly having fun. However, when Iori's sister, Shiori, hears about his behavior, she decides to take matters into her own hands—and bring him back home to make him take over their family's inn.

Despite her best efforts, Shiori temporarily gives up as she sees how Iori has grown attached to Grand Blue and his friends. As Iori and the rest of the Diving Club continue to party like there is no tomorrow, they end up in all kinds of bizarrely amusing situations, still somehow managing to hone their scuba diving skills!

Grand Blue – Season 2

Entertaining as hell and insanely fun. It genuinely hurts when the season ends—but at least Season 3 is already scheduled, so thank god for that. This anime is pure chaos, laughter, and good vibes.

Season 1 relied heavily on naked jokes, and I honestly expected more of the same here. But Season 2 toned that down and instead brought in fresher characters and even funnier moments, which worked really well.

Plot
Honestly, it’s the same old fun. There isn’t much of a plot change this season, but I’m not complaining—Grand Blue never promises a deep story. It promises madness and laughter, and it delivers ... that 100%.

Characters
New characters were introduced and never felt out of place. They blended naturally with the existing cast and added more chaos in the best way possible.

Recommendation
Highly recommended for all comedy-loving anime fans. This one should not be missed.

Mixed Feelings

A Youtuber i follow talked about this anime at the start of the season. Until then i didn't have watched the first season yet, so I watched the first season just before watching the second. That's why this is a "Mixed Feelings" review.

This show is good, it's a lot of fun, but the first season was so increadibly over the top that this second season feels like a downgrade.

We get the same cast of characters and a few more and each one is quite unique and interesting. I never thought i would like a character like Naomi Otoya, but the situations and confusions ... involving him were so fun that I couldn't help but enjoy his screen time.

The romance between Iori and Chisa is still going nowhere but that's fine, their bickering is still a source of good comedy.

It's hard to tell exactly why this season was worse than the first, because it does has the same felling overall.

Maybe it's the character desing that looks more generic, maybe the direction couldn't get the most out of the jokes, maybe it's both or neither of these things.

But at the end of the day it's still a good anime. If you watched the first season long ago, don't worry, just watch it. If, like me, you just got out of first season, maybe give it a few months and lower your expectations a little.

Where Grand Blue Season 1 was pure fun, Season 2 completely shifts toward the romance side. The problem? Instead of bringing something new, the show mostly recycles the same sexual/ecchi comedy about asses and melons yeah, the same jokes again and again. Grand Blue was famous for wild, over-the-top comedy, but here it feels watered down and repetitive.

Like I said, Season 2 is stuck in romance mode. From the first episode to the last, all they do is throw every single girl at our MC, Lori. Some by mistake, some by misunderstanding, and suddenly every girl is chasing or colliding with the MC. It’s not ... romance, it’s recycled drama disguised as romance. There’s no depth, no actual development, just dumb filler situations designed to drag the story. Watching it feels more like punishment than entertainment.

basically S2 is mostly based on OUR MAIN character Lori , almost he got the most of the screen time in the show , every incident is around him .

Characters

Lori – The supposed MC. Honestly, in Season 2 he doesn’t even feel like the main character. He’s just treated like a punching bag. Every female character either abuses him or makes him look like trash, all in the name of “comedy.” His character is not fun anymore—it’s pathetic.

Other characters (Chisa, Aina, Kouhei, etc.) – Their role this time is basically just to support Lori. Nothing new, nothing exciting.

we also have some new characters in S2

(Sakurako) – Easily the most annoying addition. She’s a tsundere, but instead of being interesting, she’s just a straight-up bitch. Honestly, she should sacrifice herself to Truck-kun and save the audience the pain.

The gay character – His presence or absence makes zero difference. He exists, that’s it.


Overall

Grand Blue Season 2 is all about stupid lazy repetitive romance comdey, The humor is stale, the story is boring, and the characters feel wasted.
