Sagara, Sousuke

相良宗介

Sousuke is a sergeant, approximately 17 years old, serving in Mithril, a paramilitary counter-terrorist force. He belongs to the SRT (Special Response Team) of the Western Pacific Battle Group "Tuatha de Danaan". His call sign is Urzu-7 and his ID number is B-3128; he operates as the team's point-man and is an Arm Slave specialist.
Beyond being a capable Arm Slave pilot, Sousuke specializes in Arm Slave operations and maintenance, improvised explosives, small arms, survival training, anti-armor combat, trap setting, and camouflage. He is also proficient in logistics, demolitions, breach and forced entry, covert intrusion, and hand-to-hand combat. His background and experience as a guerrilla fighter, and later as a mercenary soldier, have made him more sensitive and knowledgeable about tactics and methods commonly used by guerrillas than by government-trained regulars.
Unfortunately, Sousuke is not very good at social interaction off the battlefield. He constantly causes many problems for Kaname Chidori due to his military nature. Even at school, he carries a gun, although it is loaded with non-lethal shells. He is also very bad at blending in with normal members of society because of his nature (for instance, following Kaname with stalker-like aspects and jumping off a train to follow her). That is, he lacks readily available "civil" concepts about life, such as entertainment or anything recreational, and tends to horribly misinterpret the actions of people around him (like considering a guy who dumped his girlfriend a high-level tactician who is to be reckoned with). This is shown throughout the main series in multiple episodes, and the Full Metal Panic? Fumoffu! series focuses mainly on this aspect. This part of his personality is indeed one of the main sources of the series' humor.
His previous name during his guerrilla days was Kashim, which was given to him by Majido, a strategist of the guerrilla forces in Helmajistan.
It is assumed that he changed his name to Sagara Sousuke when he left Helmajistan. While in Helmajistan, he had a close friend named Zayid.
