Voiced by: Natsuki Hanae

Kal-el is the former crown prince of the Balsteros Empire, Prince Karl La Hire, whose monarchy was overthrown by the Wind Revolution. While imprisoned with his mother, seeing a plane flying in the sky cemented his aspiration to become a pilot. After a month in the prison, he was adopted by Michael Albus. Due to unpleasant memories of the Wind Revolution, he has an absolute hatred towards Nina Viento. He enters Cadoques High's Aerial Division along with Ariel. He falls in love with Claire Cruz at first sight. After discovering that Claire is actually Nina Viento, his feelings become conflicted. When he remembers his mother's words "to forgive rather than hate", he lets go of all hatred he had for Nina.

Voiced by: Aoi Yūki

Claire is a girl with the power to control wind and was called a witch by people around her because of it. She joined the Wind Revolution as Nina Viento and helped defeat the forces of the Balsteros Empire, but lost her powers in doing so. She later hides her identity as Nina and joins Cadoques High's Aerial Division, where she is Kal-el's flying partner. She falls in love with Kal-el, but is conflicted after realizing he is Karl La Hire. During the final battle with the Sky Clan, she regains her powers.

Juan Rodrigo Bandereas (ホアン・ロドリゴ・バンデラス, Hoan Rodorigo Banderasu)

Voiced by: Takaya Kuroda

The hot-blooded, "macho" instructor of the "commoner" Centezual flight class. He comes off as arrogant and selfish, and has a surprising tolerance for pain as evidenced by laughing off a punch to the ribs (and yet not a kick in the shins). Juan cares very deeply about his students, going so far as trying to throw technicians off a plane so they wouldn't force students to go onto the battlefield, as well as flying into a war zone alone and unarmed to search for survivors.

Sonia Palez (ソニア・パレス, Sonia Paresu)

Voiced by: Yumi Uchiyama

The cool-headed, professional instructor of the Van Whyl flight class, who comes from the lesser nobility. Juan and Sonia appear to have a mutual respect for each other, but she has a very limited tolerance for his inflated ego. She aids Juan in rescuing Chiharu de Lucia after her plane is shot down, but resigns soon after, when Commander Melze orders the students of Cadoques back into battle.

Congress of Isla

Luis de Alarcon (ルイス・デ・アラルコン, Ruisu de Ararukon)

Voiced by: Jūrōta Kosugi

Luis is also one of the major reasons Claire was able to continue attending the school, despite Countess Ulshyrra's efforts.

Leopold Melze (レオポルド・メルセ, Reoporudo Meruse)

Voiced by: Yusaku Yara

Commander of the flying battleship Luna Barcos, de facto leader of Isla's military, and father of Fausto. After the initial encounters with the Sky Clan, he underestimates their tactics and equipment, ultimately leading to disastrous losses later on, including the death of his son. He has to order the Cadoques students into battle, pressing their training planes into service as ersatz fighters, which he deeply regrets but sees no alternative.

Amelia Cervantes (アメリア・セルバンテス, Ameria Serubantesu)

Voiced by: Fujiko Takimoto

Isla's Foreign Affairs adviser, though roughly serving as Luis's adjutant and adviser, Amelia takes her job extremely seriously, feeling that humor has no place in it. She is one of the first Isla officers to speak with a Sky Clan pilot, and discovers that their language was very similar.

Voiced by: Takeshi Maeda

Isla's Finance Minister, who deals with the day-to-day operations of the civilian side of Isla.

Michael is Ariel's biological, and Kal-el's adoptive, father. He had been serving the new Republican government of Balsteros as a mechanic, and was present on the day of Maria La Hire's execution. Finding Kal-el after he had escaped from his jail cell, and seeing the boy's malnourished state, Michael took it upon himself to rescue the boy from his miserable fate and give him a place in his home.

Gregorio was Kal-el's father and the former king of the Balsteros Empire, who was overthrown and executed during the Wind Revolution.

Maria La Hire (マリア・ラ・イール, Maria Ra Īru)

Voiced by: Yuri Amano

Maria was Kal-el's mother who was imprisoned alongside her son in the aftermath of the Wind Revolution. She was held in custody for a considerable time after her husband's execution before her own was carried out. Before the coup and her subsequent imprisonment, Maria was a pilot (though whether in a recreational or military context is not known), and was a big influence in Kal-el's desire to become a pilot.

Others

Countess Ulshyrra (ウルシラ伯爵夫人, Urushira Hakushaku Fujin)

Voiced by: Chiaki Kanō

Claire's appointed Guardian, and a sort of "wicked stepmother" figure in her life. The Countess forces Claire to adhere to a very strict schedule and curfew, in order for her to fulfill her ceremonial duties as Nina Viento. She has threatened to pull Claire from the flight school numerous times when she felt it was interfering with her official duties. Claire is ultimately removed from the school after the first Sky Clan raids against Isla but this was due solely to Claire's emotional conflict over her role in the Wind Revolution and her feelings towards Kal-el driving her into giving up her identity, and fully becoming Nina Viento, not to the Countess' efforts.

Shizuka Hazome (シズカ・ハゾメ, Shizuka Hazome)

Voiced by: Hana Satō
