    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).

#### 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.

    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.

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)

The admiral has the students practice dogfighting and shooting, despite the protests of the nobility students' instructor Sonia Palez that they're not ready yet. Nanako tells the others she heard a rumor that Karl La Hire was on the island and had a revenge plot against Nina Viento, but everyone jokingly dismisses the rumor, but it clearly makes Kal-El uncomfortable. More flashbacks reveal that six years prior, Balsteros was the victim of a violent revolution against the monarchy, where rebel forces overran the capital and the Priestess of Saint Aldista, Nina Viento, was able to destroy the fleeing monarchy ships using her ability to manipulate the wind. The captured royal family is forced to humiliatingly bow to the new rulers of Besteros and Nina, and Kal-El's father, the king, is beheaded while he and his mother are imprisoned.

She also learns about his secret of being the former crown prince. Meanwhile, Kal-El and Claire attempt to stay warm and in high spirits, and he tells her about the first time his adopted father takes him flying, which started his love for flying. They are soon rescued the next day, and a clearly angry Ariel beats him up for worrying her so much.

A priest from the Saint Aldista church was able to take her into control her powers, and she remembers the deaths of Karl's parents and his hatred towards her, and soon regrets her actions. Falling into a depression because of this, she is paid a visit by the island's navigator, Luis de Alarcon, and asked to join the island of Isla, and she accepts, changing her name to Claire. The students begin to learn how to dogfight, and it is clear that the tag team of Claire and Kal-El is far above the rest.

Feeling emboldened, Chiharu and Mitsuo continue to provide recon for the attacking Isla planes on the new enemy fleet and bombers. However, Mitsuo is shot by an enemy plane and badly wounded, and orders Chiharu to escape by parachute before he commandeers the plane away from her, to his death.

After his mom dies, he clearly resents Kal-El and the kingdom and promises to destroy everything. Ignacio douses Kal-El with a cold dose of reality on how he is running away from his problems, which shocks Kal-El from hearing the truth. Meanwhile, Nina continues to practice her now lost ability to control the wind, to no avail. An observation plane is launched to scout the enemy forces, but with little trained pilots or planes left, Admiral Melze is forced to use the students to help provide defense.

While many students follow her call, Benjamin, Ignacio, Noriaki, and Kal-El volunteer to go, to the dismay of the girls.

Although hesitant to use the students' reports at first, Admiral Melze is convinced by Nina that they are up for the job, and the two students are made temporary recon observers. Their accurate data is enough to get the Isla battleship's guns trained on the enemy battleship, but their plane is shot down in the process, with Benjamin losing his right hand before they bail out. A clearly angry Kal-El and Ignacio begin to shoot down the Sky Clan planes, but another squad of Sky Clan planes fire missiles at the exposed Isla battleship, causing severe damage including primary and backup engines to fail and the battleship to start falling out of the sky. Kal-El is able to pilot the plane by the sinking battleship, and tells them they will guide the battleship. Nina, seeing this, runs outside and is able to confess her love to him, even though Kal-El can't hear her. She then is able to summon her lost powers to summon a massive windstorm to completely obliterate the attacking Sky Clan planes, and then carry the sinking Isla battleship back to the island.

He explains that he has been sent to also discover the Holy Spring by his country but have faced a stubborn resistance from the Sky Clan, who take no negotiations with others trying to discover the Holy Spring. He warns that further attacks will destroy both of their fleets as the Sky Clan is too powerful to defeat in their current states. A messenger arrives with a message from the Sky Clan and to the group's surprise the Sky Clan will agree to a truce under one condition: that they turn over Nina to Sky Clan, as she is prophesied to be Saint Aldista's daughter and is an important figure in their beliefs. They are even willing to allow the fleets to pass through their territory in exchange for Nina. Despite the council's protests, Nina agrees to go to save the fleets. The students learn of this and Kal-El is not happy and talks to Ariel about this. He is surprised that Ariel is being somewhat cold towards his response also and wonders what it could be. The day of her departure, the two meet Nina and share a final embrace with her, and as she is leaving, Kal-El yells to her he will find the End of the Sky and find her someday no matter how many years it will take. Impressed, Ignacio vows to protect her on behalf of Kal-El until he returns one day. The combined fleet soon passes through the Holy Spring and reaches the End of the Sky, a beautiful rainbow like phenomenon, and are stunned to learn that their beliefs exist are true. With everyone safely evacuated to the fleet, the island of Isla passes through the End of the Sky and is reabsorbed. |||

| The council, along with the Levamme representatives, begin to learn more about their world. Their world is made up of three layers, with waterfalls separating each layer much like a staircase, and their world is supported by bedrock. At the end of their world is the End of the Sky, which allows for water to be reabsorbed back into the Holy Spring. The fleet is also able to pass through the End of the Sky and reappear at the other side, much to their amazement. Luis calls in Kal-El, and Admiral Merze is shocked to learn that Kal-El is actually Karl, the former crown prince. As they return home, Luis gives a speech detailing their adventure to a stunned populace back home. Karl is presented to the crowd, much to their disbelief as he is thought to have been dead this entire time. In his speech, he details his adventure and vows to retrieve Nina back from Sky Clan and force relations with them, and proclaims his love for her, much to the crowd's delight. This is all revealed to be a plot by the Foreign Secretary, Amelia, who sees this as a way to gain support using romantic drama to achieve their goals of getting Nina back. The students embrace and celebrate their graduation. Some time passes, and everyone has moved on with their lives. Karl is now a real military pilot and is ready to begin his mission to retrieve Nina back. As he leaves, Ariel punches him one more time, but it is clear that she is uncertain about her feelings for her adopted brother. The combined fleet once again approaches Sky Clan, and it's clear Sky Clan is waiting, and they prepare to do battle once more over the skies. |||
