Earthlings
A 13-year-old half-Japanese, half-British boy from Cornwall and the protagonist of the series. He is summoned to the alternate world of Flonyard, the Kingdom of the Biscotti Republic as Princess Millhiore's "Hero". He wields the Divine Sword of Biscotti, , a weapon that despite being originally a sword, can assume different forms according to its owner's preference (Cinque usually makes a staff of it). He has a cheerful and straightforward personality, always going at his own pace. Athletic and acrobatic, he loves sports as well. He was a first-year middle school student in Japan's Kinokawa International School prior to the summon. He can fire destructive energy beams from the tip of Palladion, and can create a hoverboard called the from Palladion as well, channeling the flames for propulsion. In the end of both the first and second seasons, both Cinque and Millhi expressed feelings of love for each other, although it still not clear the true nature of their relationship. In the second season, Cinque receives from Adel a special magic gemstone called the , that allows him to temporarily transform in an adult version of himself with enhanced flame powers.
Nicknamed by Cinque, Rebecca is a 13-year-old girl who studies at Japan's Kinokawa International School and childhood's best friend of Cinque. She has a busybody attitude and is the one who understands Cinque the best, and usually feels lonely when he is not around. She goes to Cinque's house every morning to wake him up for school. She has a love for fashion, games, manga, and fantasy-themed novels. She was looking forward to a promise that she made with Cinque, that her family (she and her mother) and Cinque's family (Cinque and his parents) would go flower-viewing during the last three days of Spring Break. In the second season, Cinque brings her to accompany him in his return to Flonyard, where she is scouted by Couvert to join the Principality of Pastillage as their hero. Upon accepting Couvert's offer, Becky receives from her the Divine Sword of Pastillage, , that in her hands is transformed into a broom-like rocket she can use to fly or an energy rifle. It also equips her with a deck of cards imbued with various types of offensive magic. She also receives from Valério a special magic gemstone called the that, just like Cinque and Gaul's Hero Crystals, allows her to temporarily transform in an adult version of herself with enhanced magic powers. At the end of the second season, she told Cinque that she loves him. Cinque replies to her that he loves her too though it is not clear if he loves her as a lover.
Cinque's 15-year-old cousin and an acquaintance of Becky. She is also Cinque's rival in the , a game closely related to Ninja Warrior, where she placed first (to Cinque's chagrin). In the second season, Nanami is summoned to Flonyard by Leonmitchelle to serve as a heroine under her, in the same fashion as Cinque is chosen as Millhiore's hero. The weapon she wields is the Divine Sword , which like Cinque's Palladion, assumes the form of a staff according to Nanami's preference. Ex Machina's staff form looks exactly like Palladion's staff form, save for the color scheme. She can also create ice skates from Ex Machina, allowing her to glide on and manipulate water, and can also morph it into a boomerang. Nanami also holds the distinction of being the only character to challenge and fend off Brioche, who was known as the strongest character in the entire series, in a one-on-one fight on near-equal terms for almost the entirety of the battle before being defeated, which clearly showcases her martial arts and athletic superiority over Cinque. In the third season, Nanami receives a special magic gemstone called the , that just like Cinque and Gaul's Hero Crystals and Rebecca's Demon Crystal, allows her to temporarily transform in an adult version of herself with enhanced water and ice powers.

She is the owner of the Demonic Battleaxe and Divine Sword , both of them are the treasured swords representing the country of Galette. As the leader of Galette, she has to carry the burden of living up to the expectations of her people. Witnessing Millhiore and Cinque's deaths in the near future (within one month from the point where this truth was shown to the audience) by her star-reading power, she desperately tries to avoid it at all costs and that appears to be the reason why she initiates wars with Biscotti at an alarming rate.

In the second season, Leo summons Cinque's cousin, Nanami, to serve as a heroine under her, and correspondingly gives her Ex Machina as her weapon.
