“A love that spanned 15 meters.”
After a mysterious alien race called the Gauna destroyed Earth, the last remnants of mankind survived within a massive spaceship, the Sidonia, for 100 years. Now the Gauna have returned. Once again on the brink of extinction, a humanoid weapon born from a human and a Gauna, the Garde Tsumugi Shiraui, and ace pilot, Nagate Tanikaze, rose up and saved humanity in its darkest hour.

10 years have passed. The people aboard the Sidonia have enjoyed a peaceful respite. Even Tsumugi quietly passes the days with her thoughts dwelling on the ship’s hero, Nagate.

However, Captain Kobayashi knew that true peace would not last so long as the Gauna were somewhere out there.

And now, the fate of humanity rests on one climatic battle for survival. The Sidonia’s crew’s final mission to protect the ones dearest to their hearts has begun.

Characters & Voice Actors List

Nagamichi Tanikaze

Voice Actor: Ryouta Oosaka

Garde ace from the 628th training class and sole pilot of the “Tsugumori,” he was assigned to unit TS-028 while training and later to 704. Nagate was raised by his grandfather Hiroki below decks on the Sidonia and has little knowledge of life on the surface and generally keeps to himself. After Hiroki’s passing, Nagate was arrested while trying to sneak into a residential area and steal rice. The ship’s captain then made arrangements for him to be trained as a Garde pilot. He is unable to sustain on photosynthesis like other passengers on the Sidonia and must eat solid food daily.

Tsumugi Shiraui

Voice Actor: Aya Suzaki

Tsumugi is a living bio weapon created by combining Gauna organic material with a human embryo. As many aboard the Sidonia did not accept her at first, she observed them by extending her worm-like appendages through the many ducts of the ship with some assistance from Nagate and Izana. As her notoriety grew, however, she was welcomed by the passengers with open arms.

Izana Katose

Voice Actor: Aki Toyosaki

Guardian pilot from the 628th training class, Izana pilots unit 723. “She” is in fact binary, neither male nor female and her appearance reflects it. Izana became Nagate’s first friend upon reaching the surface. While very friendly toward him, she often becomes jealous of Tsumugi and Yuhata.

Yuhata Midorikawa

Voice Actor: Hisako Kanemoto

Yuhata is a late addition to the 628th training class and the younger sister of Izumo Midorikawa, a member of Sidonia’s strongest team, the Akai Squad. She enjoys building model Guardians in her spare time.

Norio Kunato

Voice Actor: Takahiro Sakurai

He is a Guardian pilot belonging to the 628th training class and is assigned to unit 701. Extremely skilled, he boasted the highest ratings of the class. Norio is destined to inherit Kunato Developments as its 8th president, and has the pride to match his elite standing. Labeling Nagate and Izana as “bad seeds,” he refuses to accept Nagate as the rightful pilot of the heroic Tsugimori.

Honoka Sisters

Voice Actor: Eri Kitamura

Members of the 628th training class, En is assigned to unit 703, Ren to 706, and Hou to 705. The Honoka Sisters are actually 11 identical clone siblings who underwent accelerated growth and compressed mental training. While they differ very little in appearance and intelligence from their trainee counterparts, the Honoka Sisters are a mere five years old.

Captain Kobayashi

Voice Actor: Sayaka Ohara

Kobayashi is the 28th captain of the Sidonia as well as its commander. She wears a full-face mask resembling those worn in Noh theater while in the presence of the crew. Ever level-headed, Kobayashi is willing to make tremendous sacrifices to ensure the Sidonia’s survival. However, she enjoys mingling with the passengers in various disguises.
