Sound of the Sky revolves around a young girl named Kanata Sorami who is inspired to join the military after witnessing a rendition of "Amazing Grace" by a mysterious trumpeter of the Helvetian Army. Becoming a bugler, she is assigned to the 1121st Platoon stationed in the town of Seize (inspired by Cuenca, Spain)[2] in Helvetia (another name for Switzerland), where she is taken into the care of 2nd Lt. Filicia Heideman, M/Sgt. Rio Kazumiya and the rest of the 1121st Platoon. The story takes place in a post-apocalyptic world after a great war regressed humanity's technological capabilities back to early-to-mid 20th century standards.


Kanata Sorami (空深 彼方, Sorami Kanata)
Voiced by: Hisako Kanemoto[3]
Inspired by the song of a mysterious military trumpeter, 15-year-old[4] Kanata joins the army as a bugler and is assigned to the 1121st Platoon. Despite being gifted with absolute pitch, Kanata initially lacks musical prowess, but gradually improves as the story progresses. She is portrayed as optimistic and cheerful, yet dedicated to her duties as a soldier and as a member of the platoon.
Rio Kazumiya (和宮 梨旺, Kazumiya Rio)
Voiced by: Yū Kobayashi[3]
Rio is a 17-year-old[4] Master Sergeant who is also a bugler and trumpeter, and the sole instructor of Kanata in learning military calls and signals. Rio is shown to have a no-nonsense attitude and is stricter in her discipline and the issuance of orders as compared to her commanding officer. Later in the story, she is revealed to be the half-sister of the late Princess Iliya, as well as the second heir to the Arkadia family. Due to her strained family history, she joined the 1121st as a means of escape, but later leaves in order to save the peace talks with the Roman Empire and prevent war. She is later promoted to Lieutenant upon rejoining the platoon after the war ends.
Filicia Heideman (フィリシア・ハイデマン, Firishia Haideman)
Voiced by: Aya Endō[3]
The 18-year-old[4] platoon leader of the 1121st with the rank of Second Lieutenant, Filicia tends to stray away from military convention, preferring to exercise a more casual leadership. Filicia does away with addressing rank with members in the platoon so that everyone is known on a first name basis. Her kindness and gentle nature is well known by the girls as she acts as a type of mother figure to them. Prior to her commission of the 1121st, Filicia was previously assigned to an active combat tank platoon of which she was the only survivor. She is later promoted to Captain.
Kureha Suminoya (墨埜谷 暮羽, Suminoya Kureha)
Voiced by: Eri Kitamura[3]
A private and the platoon's designated gunner, Kureha is the youngest of the girls in the 1121st at the age of 14.[4] Kureha has a strong respect for military code and obeying orders. Her parents died when she was very young and she only knows of them through stories told by others. Her father was once a respected tank commander, and because of this, she took an immediate liking to Major Claus, having believed him to be the one and only "Desert Wolf".
Noël Kannagi (寒凪 乃絵留, Kannagi Noeru)
Voiced by: Aoi Yūki[3]
The platoon's 15-year-old[4] designated pilot and appointed mechanic with the rank of corporal, Noël is often portrayed as sleepy and tired, resulting in her falling asleep when in the company of others or in the middle of something. She spends most of the time repairing the platoon's battle tank, the Takemikazuchi, which is considered a technological relic from the previous age of prosperity. Initially, Noël is unsociable, but slowly breaks out of her mold due to Kanata's friendship. She was purportedly a genius in the Helvetian Academy, earning praise by military officials who used her to help them resurrect a bioweapon technology dubbed the Invisible Reaper. As a result of the terrible devastation and loss of life caused by such weapons, Noël was branded by the Romans with the moniker "Witch of Helvetia".
Yumina (ユミナ)
Voiced by: Misato Fukuen[3]
Yumina is a priestess at the local church who looks after orphaned children. She also acts as a nurse when people fall ill and is fluent in the language of the Roman Empire, which in the story is presented as modern-day German.
Claus (クラウス, Kurausu)
Voiced by: Unshō Ishizuka[3]
A commissioned officer holding the rank of Major, Claus is a despatch rider and close friend of the 1121st. He is mistakenly identified by Kureha as the "Desert Wolf" or "Miracle Claus", a tank commander of the same name and similar appearance who is renowned for his courage and service in the Helvetian army. Due to Kureha's admiration and awe for his supposed reputation, Claus finds it difficult to reveal the truth to her.
Naomi (ナオミ)
Voiced by: Mayuno Yasukawa[3]
Naomi is the owner of a glassware shop who also acts as the front man for some of the 1121st Platoon's dubious activities, including an illegal alcohol distillery.
Mishio (ミシオ)
Voiced by: Mayuko Takahashi
Mishio is an orphaned girl under Yumina's care. She is very protective of who braids her hair, since her mother used to do it for her.
Seiya (セイヤ)
Voiced by: Mana Hirata
Seiya is an orphaned boy under Yumina's care. He is hostile towards soldiers, whom he blames for his parents' deaths, although his view of the soldiers at the Clocktower Fortress improve with the passing of time.
Iliya Arkadia (イリア・アルカディア, Iria Arukadia)
Voiced by: Ryoko Ono
The late first Princess of the Archduke of Arkadia and the half-sister of Rio, she died two years prior to the story. Iliya was the trumpeter of her squad and is known for her renditions of Amazing Grace, which at various times in the past had inspired members of the 1121st platoon.
Aisha Aldola (アーイシャ・アルドーラ, Āisha Arudōra)
Voiced by: Nami Miyahara
Aisha is a Roman scout that Kanata and Kureha discover unconscious and injured while on patrol. While in their care, the platoon quickly befriends her despite the language barrier (as she only speaks in her native tongue) and her status as the enemy. Aisha is revealed to be connected to Noël in the past, having been a survivor of the onslaught caused by the Invisible Reaper.
Shuko (シュコ)
Shuko is a northern white-faced owl that the girls find and decide to keep as embodiment of their mascot. He is thought to have been owned by Princess Iliya in the past.
Hopkins (ホプキンス, Hopukinsu)
Voiced by: Naoya Uchida
A feared Colonel of the Helvetian army, also known as the Demon of Vingt. His desire is actually to provoke war from the Roman Empire. He plans to do this by kidnapping and executing Aisha, but she escapes and is found by the 1121st Platoon, who foil his plans and end the war.

While looking at a bell owned by Rio's father, an owl steals it, forcing Rio to stop Kanata falling off the balcony trying to get it. As Rio participates in the festival, Kanata decides to search for the bell. She finds it hanging off a ledge, but when she goes to get it she falls into the lake, where she sees the golden skeleton of a winged creature.

When Kureha takes Kanata to see the tank of the squadron is housed, which is in the process of being repaired, Kureha expresses her depression because the military often ignores the squadron's existence. Later that night, Noël and Kanata claim they saw a ghost in the barracks, so Kanata and Kureha are sent to investigate. They learn the place used to be a school. Kureha laments that their platoon is in the middle of nowhere and is generally ignored.

When Kanata wakes up, she tells Rio that she has always been useless and has caused troubles for others. She also mentions to Rio that she always wanted to play a song, having heard it from a trumpeter she met when she was younger.

Kanata and Noël head to a glass works factory, where they are having trouble replicating the optical lens needed for the tank. Kanata reassures Noël that it is not the machines that are good or bad, but the people who use them.

With little options left, and after a few civilians get arrested, the girls use the restored Takemikazuchi and are victorious in a battle against Hopkins and his men. Upon reaching the field between the approaching Roman and Helvetian armies, Kanata sounds a cease-fire signal, but is ignored. She then plays Amazing Grace, which temporarily stalls both forces. Before hostilities are about to resume as the song ends, Rio arrives, accompanied by the Helvetian Royal Guard.
