Ash-blond, sharp-looking young man. Loewe is left-handed. Acting in secret via his pseudonym "Lt. Laurence" he was a constant obstacle to Estelle and co. He is part of the mysterious organization "Ouroborous," and has been crowned with the title "Emperor of the Sword" via his daunting sword skills and battle prowess. In the endless depths of his deep purple eyes sometimes shows a feeling not wanting strangers to get close to him.
Loewe had once lived in Hamel Village at the frontier between the Liberl Kingdom and the Erebonian Empire. He spent most of his time with Karen, his girlfriend and Joshua whom he considered his brother and best friend. Loewe had the dream to become a Bracer, a dream that he never was able to fulfill ever since Hamel was ravaged by forces of the Erebonian Empire. He lost his love, Karen, and decided along with Joshua to join the Ouroboros organization, his heart filled with hatred. It is suggested that during his training with Ouroboros he met The Leader himself and was admired by the Second and Seventh Angis in the organization.
Under the identity of Swarzritter, Loewe is resurrected by the Arca of Recluse. He appears several times during the group's travels, mocking Kevin. At the Farewell Arena, he wants Joshua along with Kevin and the others to defeat him first if they want to know his identity. After defeated and his identity is revealed, he explains to the group about why he is resurrected. If the group consists of party members who know Loewe more such as Renne and Estelle, there will be extra dialogues. Finally, he and Joshua can say goodbye with each other for the last time and he returns to Karen's side.
