Sidonia is in the midst of its most dangerous battle yet when we last checked in with the crew. The Gauna had just laid waste to the moon, and all they cared about was how to save it. With Kenji still missing and Nagate’s actions unknown, Sidonia is in danger of losing everything.
When we return to the Universe, Commander Kubal believes that this is all part of some rouse by the Tsugumori pilots. Meanwhile, Admiral Nemetoro must contend with revolutionaries on board. It’s believed they are attempting to take over Sidonia and make it their own. No one can be trusted, which means that many innocent people will die before things get better. On the far finish of the solar system, Muginami has gone into deep sleep mode in order to survive how long she has to wait for Nagate (and her brother Shizuka) to return home.
As for our heroes up on the surface of Enceladus, Kenji made contact with Killy, who is still trying his best to bring down the Wall. They were successful, and this will be a positive thing for them in the end. However, they’ll have to live with the consequences of their actions along the way. The Gauna are now more powerful than ever, and it’s only a matter of time before they come storming back to finish what they started.
Kenji may not take on all of them at once, so he needs an army behind him. To fight fire with fire, he must design a weapon from Tsugumori that can beat the Gauna at their own game. The people of Sidonia will surely see this as a major threat, but it’s something that must be done if anyone is going to survive past Season 3.
Knights of Sidonia Season 3: Cast
The new cast associates include (from left to right): Admiral Yamamoto, Miru Datkins, Tanikaze Shizuka, and Kaito Tatsumiya.
Admiral Yamamoto is the newly appointed admiral of Sidonia who begins questioning Commander Kubal’s decision-making skills during difficult times. It doesn’t help that she considers him too young for the position of admiral.
Miru Datkins is a 15-year-old girl who was born in Sidonia while her parents were in suspension. Her father disappeared while her mother became extremely ill and died soon after. Since then, it’s been just her and her brother Tanikaze Kaito who has taken care of her since they were kids. She’s quiet, reserved, almost always keeping to herself or with her brother. Despite this, she decides to go out for dinner on the night the Gauna attack the moon colony thinking that it would be safe because of all the sensors surrounding them…but nothing could prepare them for that. Her fate is unknown, but she would likely have died in the attack.
Kaito Tatsumiya is another 15-year-old boy who lives with his sister Shizuka. He takes care of all their housework and does most of the cooking as well. Despite being younger, he acts much older because she essentially raised him after their parents disappeared during a Gauna attack years ago. Because of this, they are extremely close to each other though he doesn’t mind her company even when they are having dinner alone together on the day of the moon colony’s destruction.
Tanikaze Nagate is the main protagonist of Knights of Sidonia who was originally built like a tank (literally) to fight Gauna. However, his design had to be changed after he piloted Tsugumori with both Izana and Ochiai, which caused physical changes in his body. Not only did he gain human-like features, but he also gained incredible strength that makes it difficult for him to go back into hibernation when needed. A cycle that’s all too familiar for Nagate at this point since he can’t remember what happened during his time spent in hibernation earlier on…
Nagate continues to have visions of another woman, which complicates things even further though it remains unclear if she is actually real or if it’s a memory created by an imprint his mother left behind.
Knights of Sidonia Season 3: Main Antagonists
Nagate may have to fight a deadly Gauna once again, but he won’t be doing it alone this time. While the Tsugumori is now able to fly and shoot beams from its hands as well as fire multiple projectiles at once from its back, there is still much for both Killy and Tanikaze Nagate to learn about fighting these creatures as they continue their journey towards the Galactic Spiral Riser. To gain intel on what could defeat them, they must first research just how the Gauna has evolved over the last 10 millennia since being introduced into space by the so-called flower of life. But even if a new weapon is designed, can it really defeat this Gauna that threatens the existence of Sidonia today?
