Knights of Sidonia 2.12

Decisive Battle

Part of the Crimson Hawksmoth works its way into the cockpit of Tanikaze's garde, the Tsugumori. It looks just like Hoshijiro. It almost gets him but Izana manages to activate some of the garde's systems. Tanikaze and destroys the Crimson Hawksmoth. The part that looks like Hoshijiro survives.

Hundreds of gaunas converge on the Tsugumori. Several of the Hayakaze attack ships arrive from Sidonia just in time to destroy the gaunas. Everyone returns to Sidonia. Life kind of returns to normal.

Entry

The reconnaissance squad is quickly cut down to just two, one of whom is Izana. The pilots and the people running the command center of Sidonia watch what's happening, unable to help. Kunato is concerned that the loss of Izana will endanger his plans. He suggests to Sasaki that they should employ the new version of the Tsugumori. Tanikaze is ordered to report for duty. He is given some instructions and then sent out with Tsumugi after Izana and the other surviving member of the reconnaissance squad.

Mozuku is riding shotgun in Tsumugi. Together they take off for Planet 9. Izana makes a discovery while she waits for help to arrive. She descends through the atmosphere of the planet. The gauna continue to follow her but after she loses her kabizashi she notices that they stop following her. She jettisons her fuel leaving her very little energy to get her around.

Tsumugi and Tanikaze arrive at Planet 9 and are quickly attacked by the hordes of gauna. They kill many of them but then the Crimson Hawksmoth emerges from the gauna horde. Tsumugi takes on the special gauna while Tanikaze goes looking for Izana.

Duty

Tanikaze and Izana investigate Senshukyo. She is convinced that he brought her to get her alone, away from the others. He still believes the directions he received from Yure Shinatose and sticks to the plan. The instructions call for them to spend the night there together. Izana takes a look at the instructions and realize that her grandmother is behind it all and gets angry.

Yuhata and Tsumugi spy on Tanikaze and Izana from a distance. Yuhata has no problem with doing so but Tsumugi feels a bit guilty about it.

A mission is sent to investigate Planet 9 of the Lem system. Izana is sent as part of the 5 person squad but Tanikaze is not. Everything goes well until it doesn't. The recon squad discovers a giant new gauna. One of them is killed and the others are in danger as the episode ends.

Knights of Sidonia 2.08

Reunion

Teams of Gardes work on repairing the breach in the hull caused by the weapons test. Tsumugi causes a bit of problems flying around the work site a little too quickly. Yuhata moves in with Nagate and Izana. They didn't invite her to but they are too polite to say no. 

Izana goes to visit Yure, her grandmother. Yure notices the changes in Izana's body and insists that they dress up in some revealing clothes she used to wear when she was younger. They get dressed up and go out for a bite to eat but then Yure gets called away and Izana has to return home alone. She is very nervous about being seen dressed such as she is.

Rumbling

The test of the new weapon goes horribly wrong. It is made from gauna parts and starts to act like a gauna. They can't shut it down. It starts to affect all of Sidonia. Surveillance for the area where the weapon's test was conducted is restricted. Yuahta send out garde units to investigate because it is the only way to get eyes on the disturbance.

Yure Shinatose tries unsuccessfully to manually disconnect the gauna from the power source and loses an eye while trying to do so. The distrubance ends when the gauna parts explode, blowing a hole in Sidona and obliterating itself. Captain Kobayashi considers the experiment to be a success and wants Yure to continue work on perfecting control over the weapon.

Knights of Sidonia 2.06

Startup

Nagate moves in with Izana. The pipes are creaking. It turns out to be Tsumugi who has crept through the pipes to visit them.

Yure Shinatose and Numi work on a new weapon. They report in to Captain Kobayashi who wants to know when it will be ready.

Nagate and 3 other pilots take part in a test of a new propulsion system. Momo Kunato, pilots Tsumugi. 

Nagate goes to the real estate office. He has an order which entitles him to a place in any sector, without restrictions. The housing office person finds him just what he wants: a remote place with lots of old piping.

Knights of Sidonia 2.05

Desire

Izana Shinatose and Tsumugi are badly injured but they both recover. Izana opts to get a robotic hand to replace the one she lost in the battle. Nagate worries about them while they heal.

Tsumugi is set up in new quarters. Izana and Nagate want to bring Tsumugi to the area where most people live but Yuhata denies that request. They go around her and find a way to give Tsumugi a glance at the living area, from a great distance.

Nagate returns from that trip only to find that he's been evicted because his living space is being given to cadets. He turns to Izana and asks if he can stay at her place.

Knights of Sidonia 2.04

Rage

Several squads of Gardes prepare for the onslaught of the Gauna cores on Sidonia. Tsumugi is enveloped by Gauna 550 but breaks free. Kunato tries to give Tsumugi orders but she is enraged by what she just went through. She attacks the gauna cores that are headed for Sidonia.

Tsumugi gets overwhelmed. Izana tries to help Tsumugi and is dealt a devastating blow. Tsumugi finally comes to her senses, grabs Izana, and heads back to Sidonia. The Gardes continue to fight the swarm of Gauna. 

The squads of Gardes attack Gauna 550, surround it but then it starts opening up. It reveals a heigus cannon which it then fires right at Sidonia. The Gardes are helpless to stop the blast but Tsumugi somehow deflects the blast so that is misses Sidonia.

Knights of Sidonia 2.03

Course

Captain Kobayashi takes over in the wake of the murder of the immortal council. She has Sidonia head for the Lem System where all out war will be conducted against the Gauna. It is also there that humanity will settle. There are people who protest the decision but they know nothing about the immortal council just that Captain Kobayashi is exercising dictatorial powers.

Nagate and Izana interact with the Chimera some more. Yuhata does some digging and finds some buried information about the Chimera. Kunato Industries supplies the military with some advanced armor. 

Knights of Sidonia 2.02

Ability

Kunato/Ochiai convinces Yure Shinatose to help him. He has begun experimenting with creating Chimera (human/gauna hyrids). He needs Captain Kobayashi's permission so that he can get more resources.

Tsumugi Shiraui, Kunato/Ochiai's first chimera, arrives in time to help Tanikaze and the others to defeat Gauna 549. Tanikaze recognizes the voice of the chimera, it is Hoshijiro.

Kunato/Ochiai introduces the Chimera to the assembled pilots and other people of Sidonia. Tsumugi attempts to be gracious but the people have their doubts. She gets excited when she sees Nagate and starts wagging her tail so violently she causes physical damage to the chamber. The crowd once again rails against the Chimera until Kunato/Ochiai ends the meeting.

Knights of Sidonia 2.01

Discord

Norio Kunato and Mozuku enter the forbidden area beneath his family's ancestral home. They find Ochiai's lab and they are quickly overpowered by deadly plants. Norio and Mozuku recover but they are no longer themselves. Norio is now Ochiai. They go to the Extraterrestrial Research Division and overpower Numi Tahiro, the scientist who is there keeping an eye on the ena that looks like Hoshijiro. Tahiro's brain is taken over by one of the creatures that Ochiai bred, a Blood Nematode.

Tanikaze learns about the disappearance of the ena that looks like Shizuka. He is down in the dumps. Shinatose doesn't know why he feels sad but tries to cheer him up. They plan a trip to a shrine but then he gets a call from Yuhata. He agrees to meet with Yuhata. Izana decides to go to the shrine by herself. He catches up to her after talking to Yuhata, who tells him the something that Numi told him, not to think about the ena and it was just an ena.
