Dragon Pilot: Hisone and Masotan

Hisone Amakasu (甘粕ひそね, Amakasu Hisone)

Voiced by: Misaki Kuno[8] (Japanese); Christine Marie Cabanos[9] (English)

JASDF Airman Third Class (later Technical Sergeant). A rookie at the JASDF Gifu Air Base who is chosen by Masotan to be his Dragon Pilot (D-Pilot). She has a habit of constantly speaking her mind without restriction, which makes her seem rude at times, even when she means well. She has a habit of belittling herself in front of others, since she was never close to anyone before and tries to accept things, rather than fight to change them. Her TAC name is "Hisone."

Nao Kaizaki (貝崎名緒, Kaizaki Nao)

Voiced by: Tomoyo Kurosawa[8] (Japanese); Sarah Anne Williams[9] (English)

JASDF Airman Third Class. A cadet at the Gifu Air Base who was initially the only person in line to become a D-Pilot; however, Masotan refused to eat her or any other potential pilot for years. She has a strong fighting instinct and often tries provoke fights with those around. In the beginning, she greatly resents Hisone and tries to bully her, but gradually warms up to her. Her mother was a D-Pilot. She later becomes a spare D-Pilot, after a specific suit is developed that entices the dragon into eating the wearer, but the effects are limited. Her TAC name is "Sexy Jaguar"

Elle Hoshino (星野絵瑠, Hoshino Eru)

Voiced by: Maki Kawase[8] (Japanese); Katelyn Gault[9] (English)

JASDF Senior Master Sergeant. A D-Pilot from Tsuiki Air Base in Fukuoka. Ever since she was young, she had wanted to be the first female fighter pilot; however, a dragon chose her as a D-Pilot, preventing her from becoming an "actual pilot," causing her much anger and self-hatred. Initially, she refuses to see her dragon as anything but a tool and object, to the point where she forces it to remain in its fighter plane form at all times. She is cool and dignified, and is very good at both academics and sports. Her TAC name is "Penguin."

Lilico Kinutsugai (絹番莉々子, Kinutsugai Ririko)

Voiced by: Satomi Arai[8] (Japanese); Erika Harlacher[9] (English)

JASDF Technical Sergeant. A soft and subdued D-Pilot from Misawa Air Base in Aomori with severe shut-in tendencies. While she tends to always imagine the worst-case scenario for all situations and has many negative thoughts, she is also very competent and clever. Her TAC name is "Jimmy."

Voiced by: Rie Kugimiya[8] (Japanese); Carrie Keranen[9] (English)

JASDF Lieutenant Colonel. Hisone's superior officer. She was once a D-Pilot candidate but was not accepted by Masotan, who instead chose her friend and colleague Moriyama, otherwise known as "Forest."

Iboshi (飯干, Īboshi)

Voiced by: Yoshimitsu Shimoyama[8] (Japanese)

Voiced by: Jōji Nakata[8] (Japanese); Doug Stone[9] (English)

JASDF Major General. The commander of Gifu base's Air Development and Test Wing and Major General. In spite of his tough-looking appearance, he is quite easy going and loves animals, including dragons.

Natsume Misumi (三角棗, Misumi Natsume)

Voiced by: Riko Fukumoto[8] (Japanese); Erica Mendez[9] (English)

The leading miko for the series' Ritual, she is an old childhood friend of Haruto. She is romantically interested in him and therefore quite resentful toward Hisone.

The dragons used as OTFs by the JASDF are habitually dressed in transforming armor shaped like military planes to avoid drawing public attention. In order to be flown, the dragons swallow their pilots, who then steer them from within their stomachs via a naturally activated holographic display control system. To protect themselves from the dragons' digestive juices, each pilot is required to wear a special acid-resistant suit. In addition, a D-Pilot must reserve her feelings exclusively for her personal OTF; if she establishes a love relationship with someone else, the bond between them is broken (this event is commonly referred to as "anastomosis").

Masotan (まそたん, Masotan) / F-15J

Voiced by: Matsunojō Kanda[10] (Japanese)

The dragon that lives in the JASDF Gifu Base and who accepts Hisone as his pilot. Hisone initially calls him "Otofu," a play on the pronunciation of "OTF," until she discovers a plaque inside him with the characters for "Masotan" written on it. His previous pilot called him "Oscar." He has huge wings and a long tail, and is both honest and serious, but has a fear of strangers. He loves to eat minor metals, commonly used in flip phones, a favorite food of his.

Norma (ノーマ, Nōma) / F-2A

Elle's dragon. Initially, she refuses to give it a name beyond the technical description of its aircraft appearance. Later, she decides to name it "Norma," derived from the Japanese pronunciation of "F-2" 普通 fuutsuu which means "normal" in English. It has a sharp body and long tail, and appears frighteningly vicious at times.

Futomomo (フトモモ, Futomomo) / C-1

Mayumi's dragon and the largest of the four, he takes on the form of a large cargo transportation aircraft. He is easygoing and loves to eat. His name means "thighs" in Japanese.

Akemi (あけみ, Akemi) / E-2C

Lilico's dragon, which takes the form of a large propeller plane. It has a fear of others' eyes and thus always hides one eye with its disk-shaped head.

Mitatsu-sama (ミタツ様, Mitatsu-sama)

A gigantic, flying fish-like monster – classified as a "Giant Organic Transformed Flyer" – large enough to be mistaken for a small island or mountain when at rest. Mitatsu awakens once every 74 years to change its resting place, and the group of OTFs perform their duty to guide him to his next destination without leaving calamity in his wake. Additionally, a ritual performed by a group of miko is needed to safely put him to sleep.

The opening theme song titled "Shōjo wa Ano Sora wo Wataru" (少女はあの空を渡る, lit. "The Girl Crosses That Sky") is composed by Taisei Iwasaki and performed by Riko Fukumoto, featuring lyrics written by Mari Okada. The ending theme song titled "Le temps de la rentrée: Koi no Ieji (Shingakki)" (Le temps de la rentrée～恋の家路(新学期)～, lit. "The Time of the Return: Love's Road Home (New School Term)") is a cover of France Gall's "Le temps de la rentrée," arranged by Iwasaki and performed by D-Pai (D-Pilots, short for "dragon pilots"), a vocal unit comprising voice actresses Misaki Kuno, Tomoyo Kurosawa, Maki Kawase, Satomi Arai and Kaori Nazuka.[11]
