Ren Nanahoshi (七星 蓮, Nanahoshi Ren)

Voiced by: Masahiro Itō

Vocalist. A first-year university student who is studying at the Faculty of Law. He could not forget the excitement of the outdoor live he saw as a child, and wished to stand on a big stage one day. However, since he is not good at communicating with other people, he would only sing on his own at karaoke sessions until he was scouted by Yūto, who was looking for vocalist for Argonavis. He is usually a calm person but will get fired up when it comes to music.

Yūto Goryō (五稜 結人, Goryō Yūto)

Voiced by: Daisuke Hyūga

Guitarist. A first-year university student who is studying at the Faculty of Literature. Born within a prestigious family in Hakodate, he immersed himself with music activities due to his inferiority complex towards his superior older brothers. He is strong-minded and optimistic, and does not doubt that he will one day become successful with his band and that his family will finally look at him. With his creed "we wouldn't know before we try it", he created Argonavis with enough confidence.

Wataru Matoba (的場 航海, Matoba Wataru)

Voiced by: Seiji Maeda

Bassist. A first-year university student who is studying at the Faculty of Literature. His father used to be a seafarer and his mother's whereabouts are unknown. He has always been with his older brother since they were small. He started to become interested in bass because his brother was in a band. He is a prudent character who makes negative remarks to those who try to talk positively. However, he does that to make the band successful.

Rio Kikyō (桔梗 凛生, Kikyō Rio)

Voiced by: Shuta Morishima

Keyboardist. A first-year university student who is studying at the Faculty of Political Science and Economics. Being surrounded by study, sports, and music to the point that he could do anything, he is nicknamed "Shindou", (meaning child prodigy) by people around him. Above all, he hoped to be a baseball player, but got hurt before the Koshien and had to give up his baseball career. He doesn't show his real emotions but will respond to people who need him and try his best.

Banri Shiroishi (白石 万浬, Shiroishi Banri)

Voiced by: Shohei Hashimoto

Drummer. A first-year university student who is studying at the Faculty of Business. He wants to make a name for himself and earn money with the band to rebuild his parents' dairy farm that was sunk with debts. From his experience of playing taiko when he was young, he showcased a powerful performance and sold himself to joining Argonavis. He made use of the fact that his drumming is surprisingly powerful from someone his height and stature to be able to join Argonavis. With a thorough pragmatism and a personality that dislikes waste, he is constantly a high tension and a mood maker.

Gyroaxia

A college students hard rock band based in Sapporo, Hokkaido.

Nayuta Asahi (旭 那由多, Asahi Nayuta)

Voiced by: Jin Ogasawara^[2]

Vocalist. He leads GYROAXIA due to his powerful vocals and overwhelming charisma. He expects nothing from his band members other than the best. However, if they are not up to his expectations, he won't hesitate to cut them off without warning. He seems to be doing all this to get back at his father, who was a legendary bandman, for abandoning him and his mother. He has no other interests other than music to the point where he initially has a disconnect with his bandmates.

Kenta Satozuka (里塚 賢汰, Satozuka Kenta)

Voiced by: Shinichi Hashimoto^[13]

Guitarist. Bewitched by Nayuta Asahi's talent, this leader of GYROAXIA spares no effort in making his name well-known. He is proficient in intel-gathering and uses it to gather information on rival bands, among others. While he adores Nayuta, he doesn't adore him as his own person rather, he adores him as a vocalist. Since he lives in different homes from Wataru Matoba, due to their parents' divorce, he worries about him a lot.

Reon Misono (美園 礼音, Misono Reon)

Voiced by: Takumi Mano^[13]

Guitarist. A stubborn man who is also very exceedingly patient. He's the enthusiastic hardworker type who won't stop trying until he excels. While he strongly opposes Nayuta's dictatorial ways, he recognizes the talent in GYROAXIA and strongly believes they deserve to be on top. The only person who has guts to bear his fangs towards Nayuta, but against someone as unpredictable as him, he always holds back from directly confronting him.

Ryo Akebono (曙 涼, Akebono Ryō)

Voiced by: Hiroto Akiya^[13]

Bassist. He committed a crime back on his home planet and was banished to Earth as punishment. His crime was "the inability to make people happy". So he will stay on this planet until he is able to make someone happy... or so he says. He's a rare kind of genius—one able to join GYROAXIA without much of a sweat.

Miyuki Sakaigawa (界川 深幸, Sakaigawa Miyuki)

Voiced by: Kōsuke Miyauchi^[13]

Drummer. He was a kickboxer before switching over to drums to get more popular. Making use of his natural strength, he engraved GYROAXIA's rhythm to anyone who ears with a flashy manner. He's nice to kids and women, looks superficial at first, but he's actually quite stoic. He's among the oldest in GYROAXIA and also admires Nayuta. However, he doesn't get along with Kenta's idea of throwing away his humanity for him.
