Kai Schulen is an identity that was used by different people at different times. This article is about the overall identity.
Kai is the Sergeant Major of Squad E, and a prodigy sharpshooter.
Kai Schulen is a Gallian who volunteered to join the Edinburgh Army when tension rose between Gallia and the Empire. He was placed in a squad that consisted mostly of other volunteers also from his homeland. Schulen excelled in many areas during training, and was promoted to the rank of sergeant major to become the senior non-commissioned officer of the squad. When the squad graduated from training and was officially commissioned as Squad E, he continued to support the newly assigned commanding officer, Claude Wallace (who happens to be from his hometown) in managing the squad.
With the rest of his squad, Schulen volunteered to go through ranger training, and performed excellent in the program as well. Near the end of the ranger training, headquarters selected him for a top secret mission, which lead to his absence from the squad for several weeks. However, missing a few weeks of training did not appear to hamper his performance, and during a sniper examination, he did so well many of the instructors were excited about his seemingly unnatural accuracy.
After graduating from ranger course, Schulen continued to exhibit excellent marksmanship, earning him the nickname "One Shot Killer". As part of Squad E, he participated in Operation Northern Cross and Operation Cygnus, playing an essential role with his leadership and marksmanship.
