Synopsis
The catastrophe, "Hammer of Eden," resulted in the loss of six billion lives and the flooding of 90% of the land. The New United Nations were formed to pursue peace on the ruined lands 14 years later. Keel is a boy living in a town called Yabitsu, an area which prospered due to the energy from the nuclear generator brought by the catastrophe. His next kin, Aoi, is the secretary general of the New United Nations. She views the catastrophe as an opportunity to create a new world in which nations can help one another overcome differences in races and religions. However, her efforts to realise that vision fail because of the unwillingness of the nations to change. Gould, a military officer, feels that the only way to make an order is through the military. Using Ulysses, a nuclear submarine, along with his crew, including Keel's brother Tean, Gould carries out a coup to declare war against the New United Nations in his attack on Yabitsu.

I genuinely can't remember a finale that left me glued to my seat not knowing what would happen next. Incredibly tense and action focused right until the last third where we finally get all the answers we need. It's a very hope-filled ending that still leaves some small bits unanswered but more as a mean to make the watcher wonder about the future than as a failure on the writers part. Great episode.
The beginning of the end. This episode starts to close the series with a final plan that Keel and Tean want to realize. The tone is properly serious and the pacing is good.
Heavily emotional chapter that starts to resolve some of the conflicts that the twins have. Keel starts to grow into a more mature person and Isla continues to be very supportive of everyone.
The tone changes constantly on this episode, swinging between big emotional moments and the usual comedy bits. Over all good, it mostly sets the final arc of the series.
A very exciting season finale in the story, full of action, plot twists, very emotional, not to mention quite moving. We see Keel and Tean seeking the end of the war by all means, and how the story of Isla, Aoi, and Captain Gould progresses, each in their own way with their vision of the world they dream of. It is canon within the story and closes the anime with a flourish.
A fast-paced episode, everything moves very quickly. Keel continues searching for a way to keep Isla and the baby alive, the United Nations is trying to prevent the nuclear bombs from being dropped, and Gould is looking for a way to win the war without firing a shot. It's canon within the story, keeps you hooked, and is quite entertaining to watch.
In this slow-paced episode, we see the submarine Ulysses being taken for repairs by the crew Keel, Teen, and Josie met earlier. Meanwhile, the United Nations discovers the submarine's location and will go to assess its condition. Keel must face a difficult decision: whether to continue his life in peace or return to the submarine with all that it entails. It is canon within the story and quite emotional due to the difficult themes it touches upon.
Incredibly tense start and an exploration into how heavy the role of Aoi is on her shoulders. Keel keeps being naive as always but the situations he gets in are very funny regardless. I'm happy the ostrich is still around, I love him.
We get to see a different side to Josie, one less collected and a bit all over the place which is a really nice change of pace. This chapter also gives us more character development for Keel. I only wish they would have given Isla a bit more to do but the chapter wasn't focused on the Ulysses so it makes sense.
A rather emotional episode, full of surprises. We have some flashbacks to the space station where we see more of Keel and Tean's character in their childhood, somewhat different from how they are now. We also see the Secretary-General facing a dilemma about whether or not to discuss the current world map, and Captain Gould having to protect his ship from damage. It's a fast-paced episode, with considerable development of both the main and subplots. It's canon within the story and entertaining to watch.
A fast-paced episode where we see Keel, Josie, and Teen trying to reach the submarine Ulysses. There's a lot of movement in the plot involving Captain Gould and Secretary General Aoi. It's canon within the story and has its share of action, deep dialogue, and some comedy. Entertaining and quite enjoyable to watch.
It's a fast-paced episode, full of comedy, bets, and plot twists. While Keel and Joshua are stranded on an island due to lack of fuel, Teen and the general secretary arrive on the same island. There are quite a few funny events, it's canon within the story, and quite a few surprises. An entertaining and quite enjoyable episode to watch.
Tense episode full of naval action. We get to see Gould's skills as a captain in full display and the desperate mesures the enemies take to try to put him down. We also get more info on the twins life on space which is nice because it gives Tean more time to shine considering the story has been neglecting him.
We see how the conflict escalates between the United Nations and Captain Gloud. Everything moves quickly, there's a lot of military strategy, some battles, deep dialogues and plot twists. It's a fast-paced episode, with plenty of tension and canon within the story, entertaining to watch and quite enjoyable.
A fast-paced episode, we see General Gould advance his offensive against the United Nations and all the geopolitical movement surrounding the advance of the Ulysses submarine. On the other hand, Keel Island discovers what the weapons carried by this vehicle were used for. It is a canon episode within the story, entertaining to watch, with quite a bit of deep dialogue on military, offensive and defensive topics.
A slow-paced episode, but with plenty of deep dialogue about the political climate, we see Keel trying to adapt, as is Isla. However, things don't go as planned, and certain events turn the plot and subplot around. On the other hand, the episode is canon within the story and quite entertaining to watch, as it includes some action scenes and others of comedy.
Very refreshing to see a character in a war setting that doesn't fully get the complexity of armed confrontations. We get to see this episode how Keel copes with all of it while also showing us how disconnected the world got after the catastrophe. I feel like Tean is very bland right now but it might just be setting for later chapters. Overall good episode.
In this slower paced episode we keep exploring the political climate of the new world. Keel also gets his whole character challenged as a nice stepping stone for development. I was worried that Isla would be just a character only defined by motherhood but she's actually very proactive, optimist and adapting better than Keel.
This episode we get better acquainted with the crew of the submarine. Captain Gould is really funny and Keel got what he deserved for being a cheater while playing.
We continue with the adventures of Keel and Teen, and we have a well-paced, canonical episode within the story. We see flashbacks to their childhood on the space station, and we see how Keel realizes that the ship he's on was the one that attacked his island. Meanwhile, Captain Gould begins to face aircraft carriers and ships that attack them. Very entertaining and quite enjoyable to watch.
