Kurz is portrayed as an outgoing and flirtatious character, often described as a womanizer who enjoys teasing others and frequently using playful or flippant language in conversation. His energetic and friendly nature allows him to be sociable and to form connections easily, though his behavior often crosses boundaries. This is especially evident in his dynamic with Melissa Mao, who frequently clashes with him due to his habit of making inappropriate remarks and engaging in sexual harassment.

In many ways, Kurz serves as the foil to Sousuke Sagara, his more serious and disciplined teammate. While Sousuke is rigid and militaristic, Kurz is casual, lighthearted, and carefree. However, beneath this laid-back exterior, Kurz demonstrates a serious and determined side. In combat situations or when confronted with genuine threats, he shifts into a focused and aggressive professional, highlighting his reliability as a skilled sniper despite his often unserious behavior outside of battle.

Kurz is depicted as a tall and attractive young man, distinguished by his shoulder-length blond hair styled into a mullet with long locks, and light blue eyes. His build reflects both athleticism and the sharpness expected of a professional sniper. As a member of Mithril, he is most often seen wearing the standard sage-green uniform issued to personnel aboard the Tuatha de Danaan, typically paired with brown laced boots.

Kurz Weber was born in Tokyo, Japan, to West German parents on April 1, 1979. He grew up in the Edogawa ward of Tokyo and attended a public school in the area until the age of fourteen. During his middle school years, his family was tragically killed, leaving him without close relatives.

Following this loss, Kurz began working as a mercenary soldier for hire, where he quickly discovered his natural aptitude for sharpshooting. Within two years, he developed into an expert sniper and later demonstrated proficiency as an Arm Slave pilot, though the source of his formal training remains unknown. Outside of his military activities, Kurz briefly worked as a model for TAG, a soldiers’ lifestyle magazine.

It is later revealed that Kurz and Sousuke Sagara unknowingly encountered one another years earlier as enemies on the battlefield in Lebanon. Each regarded the other as one of the most formidable adversaries they had ever faced, though neither realized the other’s identity. Only Melissa Mao learns the truth after hearing accounts of the battle from both men.

Kurz’s personal motivations are influenced by his past trauma. Much of his income from Mithril is directed toward covering the medical expenses and organ transplants of a girl he unintentionally injured while avenging his family against the assassin who had murdered them.

Eventually, Kurz was scouted to attend Mithril’s Special Operations Soldier Selection center in Belize, an institution that recruited candidates without disclosing its ties to Mithril. Initially suspicious of the organization, Kurz deliberately concealed his marksmanship skills, which led Melissa Mao, one of the examiners, to dismiss him from consideration. However, during an unexpected attack by a local communist rebel group, Kurz distinguished himself by saving the daughter of the Belizean president, showcasing his true abilities. This act earned him Mao’s respect and secured his recruitment into Mithril’s Tuatha de Danaan Special Response Team, where he was assigned the callsign Uruz 6.

Sousuke Sagara
Kurz shares a complicated yet ultimately strong bond with Sousuke. Their personalities contrast sharply, Sousuke is rigid and militaristic, while Kurz is playful and carefree making them frequent foils within the Special Response Team. Unbeknownst to both men, they once fought as enemies during a battle in Lebanon years prior, each leaving a deep impression on the other as exceptional combatants. Despite their differences, their time as comrades aboard the Tuatha de Danaan builds a mutual respect and trust, particularly in combat situations.

Melissa Mao
Kurz’s relationship with Melissa Mao is often contentious, as his flirtatious remarks and inappropriate advances frequently provoke her irritation. Despite this antagonistic surface dynamic, Mao recognizes his skill and potential as a soldier, and she was ultimately the one who approved his recruitment into Mithril after witnessing his heroism in Belize. Their interactions reflect both comedic tension and underlying camaraderie.

Teletha “Tessa” Testarossa
Kurz shows a degree of respect toward Captain Testarossa, though his casual and sometimes irreverent manner contrasts with her professional demeanor. While not as central to his dynamic as Sousuke or Mao, his loyalty to her as commander of the Tuatha de Danaan underscores his commitment to Mithril and its mission.

Kaname Chidori
Kurz frequently teases Kaname in line with his easygoing and flirtatious personality, though unlike with Mao, his behavior toward her is generally less invasive. He recognizes her importance to Sousuke and often provides lighthearted commentary on their developing relationship, sometimes serving as comic relief in contrast to their more serious struggles.

Kurz Weber is remembered within the Full Metal Panic! franchise as both a source of comic relief and a demonstration of the duality between levity and seriousness in warfare. His flirtatious, irreverent personality provides contrast to the discipline of Sousuke Sagara and the professionalism of Melissa Mao, creating a dynamic team balance aboard the Tuatha de Danaan. At the same time, his skill as a sniper and Arm Slave pilot establishes him as a dependable soldier whose contributions are essential to Mithril’s operations.

Among fans, Kurz is notable for his combination of humor and combat expertise, which highlights the series’ blending of military realism with character-driven storytelling. His backstory, particularly the tragedy of his family and his ongoing support for the girl injured in his past, adds depth to a character often portrayed in a comedic light, cementing him as one of the more nuanced supporting figures in the series.
