Description
Julie Sigtuna is the main female protagonist of the anime Absolute Duo. She is a young girl of sixteen years with a strikingly delicate appearance, often compared to a beautiful doll by her peers. Her most notable features are her long, silver-white hair that reaches her hips and is typically styled with twin black ribbon bells, paired with her ruby-red eyes and pale, snow-white skin. Her physical stature is quite small, as she stands only 149 centimeters tall.

Julie comes from a foreign country in Northern Europe called Gimlé, where she is known to hold the status of a princess. This origin is reflected in her speech patterns; she often uses the Danish, Swedish, and Norwegian words for yes, ja, and no, nej. Her surname, Sigtuna, is shared with one of Sweden's oldest towns. Having grown up in this environment, Julie is a native of a culture steeped in Norse mythology, which influences her perspective.

In terms of personality, Julie initially presents herself as quiet, reserved, and graceful, giving off an air of mystery. She is generally shy and soft-spoken, but this demeanor hides a naturally kind and understanding nature. She has a calm disposition and does not easily give in to negative emotions like jealousy, even in situations that could provoke them. Her behavior can sometimes be that of an airhead, and she is described as possessing a natural, unassuming charm, seemingly unaware of her own captivating beauty. Notably, she has a peculiar set of weaknesses, including an inability to swim, a tendency to get motion sickness, a susceptibility to heat, and an extreme sensitivity to alcohol, to the point where she can become intoxicated simply from the smell or from eating rum raisin gelato.

Julie's primary motivation for enrolling at Kouryou Academy in Japan is deeply personal and driven by a desire for revenge. She is an Avenger, seeking to become strong enough to avenge the death of her father, who was killed in battle. The man who murdered her father also left a physical scar on her back, which she regards as a curse, a constant reminder of her mission. This singular goal is what guides her actions and leads her to seek out the protagonist, Tooru Kokonoe, whose own quest for strength aligns with hers. She takes a keen interest in him from their first meeting and eventually requests that he teach her his ultimate technique, which she calls Mjolnir, to aid in her vendetta.

Her role in the story is cemented when she becomes Toorus Duo, his partner in the schools unique battle system. The two share a dormitory, and their relationship is the emotional core of the narrative. She refers to Tooru by the nickname Thor, seeing a resemblance between him and the powerful god from her homeland's mythology. Initially, she may see a reflection of her own father in Tooru, but this perception gradually evolves as she comes to care for him as an individual. Their bond is built on mutual trust and a shared understanding of pain and loss, making him the person she is most open and vulnerable with. He becomes the person who helps her control her darker impulses. Her key relationships also include a friendly rivalry with Lilith Bristol, as she shows signs of jealousy and a desire to prevent Lilith from getting too close to Tooru.

Julie undergoes significant development throughout the series, largely centered on her identity as a vengeful Avenger. When she is reminded of her father's death or overwhelmed by rage, she can enter a dangerous state known as Julie`s Fang or the Curse of the Fang. In this form, her speed and power are greatly enhanced, but it also causes damage to her own body. It is through her bond with Tooru that she is able to prevent the activation of this curse, finding a new purpose and strength in protecting him rather than solely seeking revenge. She evolves from a girl who had abandoned all emotion for the sake of revenge into someone who can once again value connection and trust.

Regarding her abilities, Julie is a highly skilled fighter. Her Blaze, a weapon manifested from her soul, takes the form of a Sword Type known as the Twin Blades or Double Blades, a pair of black swords. She is extremely adept at swordplay, capable of unleashing quick, consecutive slashes that put relentless pressure on her enemies. Her true power, however, is her exclusive ability called Wind Jerzu (known in some sources as Tenbuu or Celestial Soar). This ability allows her to step on and kick off the air itself, generating brief force platforms that let her maneuver in midair, evade aerial attacks, and perform high-speed dashes, limited only by her stamina. Her combat prowess and graceful fighting style have earned her the epithet of an angel bearing black wings.
