After barely escaping a collision with a gigantic Gauna at the cost of many human lives, Kobayashi—the captain of the spaceship Sidonia—is prompted to change her political paradigm. Once she seizes full power, Kobayashi aims to eradicate the Gaunas from the Lem system where former Sidonians have recently established a colony. Her ambition is justified by two breakthroughs: the development of highly effective, long-range anti-Gauna weapons, and the creation of Tsumugi Shiraui—the first human-Gauna chimera possessing great destructive power.

Facing hostility toward chimeras and her uncertain large-scale military expedition, Kobayashi enlists the help of the new elite pilot Nagate Tanikaze. Due to his personal experiences with Shizuka Hoshijiro and Benisuzume's placenta, Tanikaze soon develops a close bond with Tsumugi. As the final battle against humanity's most formidable opponent approaches, Tanikaze tries to enjoy the last days of peace with his friend Izana Shinatose—all while Kobayashi secretly pursues the development of an experimental weapon that could very well lead to the complete destruction of Sidonia.

Sidonia no Kishi has always been one of the most underrated anime series ever in my mind. Actually I'm genuinely confused as to why it isn't higher rated than it is because I swear I almost never see anyone say anything negative about it. It's an anime which is not afraid to kill off characters, has a storyline on an epic scale, excellent usage of battle CGI and probably the best sound directing I have ever heard. Overall it's an incredibly joyride from start to finish and I really wish more people would give it a shot.

Mixed Feelings
It's truly perplexing to see how often anime enthusiasts overlook Sidonia no Kishi (Knights of Sidonia). It's a show with a tried-and-true formula for mainstream success. With a dense bishounen protagonist that catches the fancy of all the female characters, a premise that warrants lots of over-the-top carnage and narrative twists, a simple setup that requires very little qualifiers to buy into, and even less thought process to grasp; it's easy to watch, easy to merchandise, and made for mass consumption. But for reasons beyond comprehension, it's only viewed by a few stragglers that come upon it by happenstance, with the only reasoning I could ...

Finally, the second season becomes available on Netflix as of July 3rd, and honestly I just plowed through all 12 episodes like a junkie with a drug addiction.

Picking up where the last season ended it seemed to focus more on Nagate's personal life and his personal Heram, which brings up something I consider to be a flaw. For me, to have the full female cast fall for Nagate pulls away from the series plot, which is a shame since we only get 12 episodes with the possibility of not getting another season. We get it, he's a bad ass. 7/10

This is ...
