Protagonist of the series, Kanata joined the military to learn how to play the trumpet and was assigned to the 1121st Platoon as a bugler. A cheerful and optimistic person, her presence helped to lighten the mood within the platoon.
A-Cup Angst: It only comes up in one scene, but Kanata is aware of Rio and Filicia's assets.
Informed Flaw: Kanata claims to get lost a lot. She gets lost exactly twice, both cases shown in the first episode. She does, however, get easily distracted, and is prone to wandering off her path if something catches her eye.
Meaningful Name: Her given name is written with kanji that mean 'the other side', 'distant' or 'over there'. In episode 13, she declares that she'll go with Rio to find the promised land at the other end of the world.
Shaggy Search Technique: Kanata has a knack for stumbling upon interesting things, be it ancient diaries, automated watchposts or giant winged skeletons.
Super Senses: Her hearing. It starts as perfect pitch, and then heads into the "no one could have heard that" territory.
Women Drivers: By the second OVA she's already driving the platoon's jeep. Although she drives slooowly, she gets distracted easily.
Second-in-command of the 1121st Platoon, Rio appears as a cool and unflappable person with a no-nonsense attitude and can be very strict in demanding military discipline and issuing orders. However, she also cares a lot about her fellow members, which makes her greatly admired by the younger members, especially Kureha.
Achilles in His Tent: The first arc of the series is Rio mulling over whether to keep ignoring the family that snubbed her for years and keep her freedom or give in, get into an arranged marriage and stop a war.
The designated gunner of the 1121st Platoon, Kureha is also the youngest member in the platoon. However, she is perhaps the most serious member and is a stickler for military regulations. Greatly admires Rio and Major Klaus.
A-Cup Angst: Could be, she looked a lil displeased, when Kanata looked at Rio's and Filicia's, but not at her's.
Cry Cute: She drops her professional facade and let's out the waterworks when the rest of the crew decides to go AWOL and stop Hopkins plan to reignite the war with Rome. She goes with it, of course.
Tsundere: She might act tough and professional but she's actually a softie. "I-It's not like I did it for you or anything like that..."
With Due Respect: She's the most military-minded of the crew, pulling rank on Kanata during the second episode on their tour through the base. When Filicia decides to hide Aisha the enemy soldier she properly objects.
The designated driver and mechanic of the 1121st Platoon, NoŽl is a taciturn and reserved person who spends much of her time tinkering at the platoon's tank Takemikazuchi.
The Atoner: Encouraged by Yumina to make up for her role in the Invisible Reaper plague, she pilots the Takemikazuchi against her own army in episode 12.
Bokukko: She uses this male pronoun to refer to herself.
Broken Bird: Machines don't betray you. Unlike Colonel Hopkins, they won't take advantage of a little girl to recreate biological weapons of mass destruction. Thanks to Kanata and Aisha, she gets better.
Bunny-Ears Lawyer: She may not answer you while driving, wonder at a pillbug, fall asleep at random and be quite laconic, but she can repair anything, save those pesky Black Boxes.
Child Prodigy: Singlehandedly repaired the facility used to manufacture a biological weapon known as the "Invisible Reaper" as a little girl.
Sugar and Ice Personality: The Stoic subtype. Noel says very little and uses as few words as possible to say it; however, she's severely emotionally scarred by her part in the Invisible Reaper, warms to Kanata and Kureha inside of a few months of Kanata's arrival, and wants to become 'a lovely wife'.
Teen Genius: Repaired the super-advanced Takemikazuchi alone, in an old, dilapidated high-school gym and achieved fluency in GermanHoly Roman in just under two months.
Terse Talker: NoŽl is pretty concise when she talks. While she is sober.
Leader of the 1121st Platoon, Filicia adopts a very relaxed approach in commanding the platoon, beginning with her insistence of First Name Basis amongst platoon members. She cares a lot about her subordinates and wanted them to be as happy as possible during their time in the Clocktower Fortress.
The Anti-Nihilist: In episode seven she declares life to lack meaning but for the one people give it themselves, and the meaning of her life is to protect her squad mates/surrogate family.
Beware the Nice Ones: She doesn't hesitate for a moment to put a gun to the head of Colonel Hopkins and later shut him up with a warning shot in episode 12.
Call Back: During the battle of Vingt-et-un, shortly before Filicia's entire tank platoon was killed, Lieutenant Olga gets the tank moving with 'Alright, let's go, my girls!' During the Let's Get Dangerous scene in episode 12, Filicia says the same thing to the girls of the 1121st.
Meganekko: Pretty, always smiling and composed, giving orders that sound like suggestions, and a tad vulnerable.
A Mother to Her Men: Filicia lists among the rules of the fortress that no one is to be addressed by rank, and she does every kind of menial tasks not usually performed by officers, like cleaning up the bathroom in episode 2.
Scary Shiny Glasses: Her glasses hide her eyes for serious effect in episode seven and for laughs in the first OVA.
Shell-Shocked Veteran: In episode seven it is revealed that Filicia is the lone survivor of her previous unit and got chronic hallucinations and survivor guilt out of her ordeal. Doting on her unit is her way of coping with it.
Stepford Smiler: She keeps all her serious psychological issues to herself.
Survivor Guilt: Her crew was killed during Vingt-et-une, and she started having hallucinations urging her to join them.
A mikonun well, she works at the church and takes care of the orphans, all right?
Faux Fluency: Whereas Nami Miyahara's Aisha is pretty fluent in German - err Roman, Misato Fukuen clearly isn't. Fortunately Sister Yumina isn't supposed to be, being Helvetian, which means Roman is likely her second language.
Nuns Are Mikos: An inversion of the usual example; she looks more like a miko, but acts more like a nun.
Can't Get Away with Nuthin' : She breaks a leg, almost freezes to death, gets groped, gets hunted as an excuse to ruin the peace talks and then shot, all just for crossing the frontier to try getting a peek of her grandmother's town of origin.
VersŲhnlich: Aisha forgives NoŽl for her role in the Invisible Reaper plague in episode 12.
Du hast genug gelitten, deshalb vergebe ich dir, auch wenn dir sonst niemand vergeben sollte. You have suffered enough, therefore I forgive you, even when probably no one else will.
