Dietrich was Claymore No. 8 of the final generation. She has demonstrated great cunning by tracking Helen and Deneve as they travelled west. It is also added that she kept her current pace while tracking their Yoki. Dietrich possesses a strong sense of duty. She also possesses great honesty. She is willing to tell The Organization about the existence of the Seven Ghosts if asked about it. However, despite her fierce loyalty to The Organization, she feels she must help Helen and Deneve as a way to pay back the debt she owes them. She appears to have good deductive skills and a serious mind because she immediately analyzes Helen and Deneve's goals and then prioritizes the safety of her teammates. She has been described as "persistent" and "following instructions to the letter" by Galatea , who calls her "Tracker Dietrich," as she has been previously involved in tracking down Galatea. She will soon join the Seven Ghosts in an attempt to bring the Organization to its knees.

Claymore
When a shapeshifting demon with a thirst for human flesh, known as "youma," arrives in Raki's village, a lone woman with silver eyes walks into town with only a sword upon her back. She is a "Claymore," a being manufactured as half-human and half-youma, for the express purpose of exterminating these monsters. After Raki's family is killed, the Claymore saves his life, but he is subsequently banished from his home. With nowhere else to go, Raki finds the Claymore, known as Clare, and decides to follow her on her journeys. As the pair travel from town to town, defeating youma along the way, more about Clare's organization and her fellow warriors comes to light. With every town cleansed and every demon destroyed, they come closer to the youma on which Clare has sought vengeance ever since she chose to become a Claymore.
