After destroying Earth many years ago, the alien race Gauna has been pursuing the remnants of humanity—which, having narrowly escaped, fled across the galaxy in a number of giant seed ships. In the year 3394, Nagate Tanikaze surfaces from his lifelong seclusion deep beneath the seed ship Sidonia in search of food on the upper levels, only to find himself dragged into events unfolding without his knowledge.

When the Gauna begin their assault on Sidonia, it's up to Tanikaze—with the help of his fellow soldiers and friends Shizuka Hoshijiro, Izana Shinatose, and Yuhata Midorikawa—to defend humanity's last hope for survival, and defeat their alien foes. Sidonia no Kishi follows Tanikaze as he discovers the world that has been above him his entire life, and becomes the hero Sidonia needs.

A very good series, there are a few things that bog it down. The series is a bit slow to start, but it progresses and gets better and better, the internal politics district from the story line and take it in directions that lead nowhere.

Sidonia no Kishi, or Knights of Sidonia, is an alternative future where mankind flees like a pussy from an ever impending extinction.

Straight off the bat, I would like to say that Sidonia no Kishi has a very interesting and eye-catching idea to the whole show. The way humans live in this O'Neill cylinder-ish space station and that there are many different layers of the station. Also, clouds and lakes are even included to make it seems as if it is Earth. Kinda reminds me of Made In Abyss. However, the flaws of the show are quickly revealed as the show progresses in the first few ...

Sidonia no Kishi, aka "Knights of Sidonia," can best be summed up as a collection of interesting elements that never reaches it's potential.

The story is set in the distant future, featuring space ships, war, a third gender, and super powerful aliens known as Gauna. The Gauna in particular is where the story reaches it's peak; these super-powered aliens which resemble machines are incredibly deadly and constantly evolving. You can really feel the fear the characters do when their squads are being cut down like butter, having to watch their comrades gruesomely die screaming.

The third gender that is introduced is also one of it's finer ...
