He learns a powerful punch attack to use in conjunction with his Blaze. Julie sometimes refers to him as Thor.

She is from a village named Gimlé in Scandinavia. Her Blaze is a Sword Type, known as Twin Blades. The reason she came to Japan and enrolled at Koryo Academy is that she wants to get stronger to avenge her family's death; the scar on her back serves as a reminder of the incident. Because of this she seeks out Tor for help and to teach her his Final Move. Julie says "Yes" and "No" in Danish/Swedish/Norwegian: "Ja" (ヤー, Yā) and "Nej" (ナイ, Nai). One of her interesting features is her single strain of hair that stands and moves around

She is very much into martial arts and Shogi. She can never tolerate idly work, so she always wakes others when they're about to be late. Being a vegetarian, she often gives Tor a plate of vegetables to maintain his stamina and power. Her Blaze is a Kusarigama.

Miyabi Hotaka (穂高 みやび, Hotaka Miyabi)

Voiced by: Ayaka Imamura^[2] (Japanese); Ashleigh Domangue^[3] (English)

Tor's classmate who forms a Duo with Tomoe. She is a buxom girl who tends to be shy around others.^[4] Her shyness, especially around boys, comes from how she used to be in an all-girls school before coming to Koryo Academy. She lacks stamina that keeps her from doing any physical activity for long periods of time. She eventually comes to realize she is in love with Tor and confesses, however, he instead turned her down telling her that he's too weak (having a flashback of his sister's death). Despite his rejection, she takes Tor´s words to her heart, even accepting Equipment Smith´s offer to become stronger, getting a Unit suit, despite having to fight against her friends. Her Blaze is a huge and heavy lance that is capable of doing large scale destruction, however, she has a hard time using it as she lacks stamina.

Lilith Bristol (リーリス・ブリストル, Rīrisu Burisutoru)

Voiced by: Haruka Yamazaki^[2] (Japanese); Caitlin Glass^[3] (English)

A transfer student from England came from an affluent family. She is a very exceptional student who at a young age has learned how to shoot and hunt, however, she is also selfish and arrogant. She is called an "Exception" and due to this, she claims to be able to do anything regardless of the rules. She went to Japan in order to form a duo with Tor after hearing news about his capability and being special just like Lilith, however much to her disappointment Tor declines. She later falls in love with Tor, and declares he will be her future husband and win his heart. Though she is officially enrolled in Koryo Academy, she never attends class claiming that she had already finished her studies a long time ago which is why she prefers loitering around the school garden sipping tea with her confidant Sarah. Her Blaze is a rifle, and she is a superb marksman. Though she is armed with a weapon that she can fire from a distance, she is surprisingly very agile to the point that she can shoot anybody at point blank range.
