Dietrich

Dietrich was the current generation's Claymore #8 but has since been demoted to a yet unknown rank. Dietrich's skill surprises Helen and Deneve as she evades being knocked unconscious, saves Helen and demonstrates either a strong improvised attack or unnamed skill.

Etymology
"Dietrich" is a male German given name. However, it can also refer to, an actress who was often typecast into the roles of strong, independent, but emotionally cold women, which describes Dietrich's personality very well.

Appearance
Dietrich appears to be a fairly young Claymore and is shorter than Helen or Deneve. Her hair is long and she wears it in two bunches. She wears the traditional Claymore uniform and has a Claymore's silver eyes.

Personality
Dietrich possesses a strong sense of duty. She is fiercely loyal to The Organization, but 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 of Galatea.

Employment as a Claymore
Dietrich is first seen fighting an Awakened Being with a small group of Claymores while being watched by Helen and Deneve. Her team (#8 - herself, #28, #35, & #42) is very inexperienced and their underpowered team is also at a disadvantage because of poor tactics in allowing the awakened being battle to move into a river, which costs them their primary advantage of mobility. It isn't long until she is the only one left still standing.

She tries to continue fighting the Awakened Being alone, but she is fairly easily outmatched and gets stabbed lightly in the stomach by one of its tentacles. It is then that Helen and Deneve join the fight, each cutting off an arm before turning their attention to her. They both try to knock Dietrich out, but she is quick and evades them both, which impresses Deneve. She quickly determines that Helen and Deneve are friends and not foes and pulls Helen out of the way of the Awakened Being's tentacles. She then turns her attention to her three injured comrades and carries them to safety with the help of Helen and Deneve, whom she believes are Secret Warriors on an important mission. They all then return to fighting the Awakened Being. Deneve manages to blind it, whil Helen uses her Drill Sword technique on its head. Dietrich attacks after Helen, using the Awakened Being's body as a spring to reach a height higher than normal. Then, using that height and the power of gravity, she cuts the enemy in half with a downward slash.

Travelling with Helen and Deneve
After killing the Awakened Being and checking on her comrades Dietrich thanks Helen and Deneve, but refuses their request to keep the incident a secret from The Organization, saying she could never lie to The Organization because she swore not to. Helen and Deneve decide to leave but Dietrich follows them and although slower, manages to catch up with them using her surprisingly high stamina. She suggests that she could follow Helen and Deneve by pretending to be kidnapped, therefore meaning she woudn't have to lie to The Organization. When this fails she suggests she could lead them through the south as it had changed in the past seven years, suggesting she knew they were survivors of the Northern Campaign. She tells them that almost all the towns in the south were gone and also that they shouldn't continue as there were demons.

When they reach the next town Helen and Deneve enter in order to find Isley, who they believe is the 'Demon' Dietrich was talking about. While Helen and Deneve encounter Isley in the town the 'Demon' appears in the forest outside of the town before Deitrich, who hides behind a tree and panics at the appearance of the shadowy figure. While Helen and Deneve are engaged in the midst of a fight with the 'Demons' and Isley in the town, Dietrich quickly saves Deneve by stabbing a 'Demon' from the back before it is able to attack Deneve and escapes with Helen and Deneve out of the town. She then explains to them the true nature of the 'Demons', whose true names are the Abyss Feeders. It is unknown whether this level of knowledge is common for all post-time skip Claymores, or if Dietrich found out all of this information herself, a la Miria.

She has since left the company of Helen and Deneve, and has left for Rabona upon Deneve's request to update Miria and Tabitha about the developments regarding Isley and the new Absyss Feeders. However, she declined further information to Miria upon further questioning, expressing loyalty to the Organization, and states that her delivery of the message to Miria is simply a means to repay her debt to Deneve and Helen.

Repaying the debt
Dietrich appears again in the end of chapter 101 to save Yuma from the yoma spike creatures spawned by the merged Luciela-Rafaela being. It is unknown why she was in the region but her motivation seems to be repaying the life debt she owes to Helen and Deneve, as she immediately identifies Yuma as their companion (despite never meeting her before, but probably by Yuma's outfit) and proceeds to help her without hesitation. As it turns out, she didn't plan to rush head on at the unknown enemy: instead, she brought a group of Abyss Feeders with her. These Feeders are apparently the ones who were sent after Riful but since Riful was killed by Priscilla, they have lost their target and were instead gnawing aimlessly at a piece of her clothes. Using this piece as a bait, Dietrich (having studied the Feeders extensively earlier) has lured them to Yuma's location and sicks them onto the yoma spike creatures. The Abyssal Feeders' regeneration abilities allow them to survive combat with physically superior enemies and also, apparently, grant them immunity to yoma spike parasites. Additionally, just as Dietrich expected, an attempt to parasitize the Feeders makes them start feeding upon the yoma spike creatures instead of their intended target.

At that point, she also mentions she was demoted by the organization for failing a mission.

She is seen following Yuma and Cynthia to a cliff side. She had apparently suffered damage to her left eye, but makes no notice of this. Upon hearing Cynthia state that Helen and Deneve were near the Destroyer, Dietrich rushes down the cliff side right after Yuma scolds her for being reckless towards the Destroyer in hopes to help the both of them even if it costs her her life in order to fulfill her agreement of repayng the debt. As the three reach Helen and Deneve, Yuma rushes over to heal Deneve's arm as Dietrich asked about the situation. Helen relunctantly told Clare was dead, but Cynthia senses an aura that tells her otherwise. Dietrich listens as Deneve explained her analysis to the them all.

Following the Attack on Rabona
Once Rabona was cleared of the Yoma threat, the Ghosts decided to attempt a rescue mission into Organization Headquarters to retrieve Miria - as Devene states that she's not content to simply "believe" Miria fell in battle. Deitrich stops the group briefly, inquiring if the assault on Rabona was engineered by the Organization. After Devene attempts to dismiss Deitrich, by releasing her from her debt, a then uncommonly emotional Deitrich explains that her hometown fell in a raid similar to Rabona's. Devene offers Deitrich to follow them back to the Organization and that if she comes to different conclusions than the rest of the group she would be free to cross blades with the Ghosts. She accepted the offer without a word spoken and began to follow.

Deneve and Helen
Dietrich was impressed by the power both Helen and Deneve showed while saving her and her team and seemed determined to pay them back. She showed concern for their safety when they ran into the Abyss Feeders and Isley, showing she wasn't only helping them to repay her debt.

The Organization
Dietrich seems to be fiercely loyal towards the Organization, shown when she refused to give Miria any more information Deneve had told her to give. She also said that she could never lie to the Organization and tells Miria she will fight against them for the Organization, should Miria and the others attack it.

Galatea
Dietrich was in charge of tracking Galatea, who she calls "Renegade Galatea". She seems genuinely surprised to see Galatea in Rabona with Miria, but the two don't seem to harbour any dislike for each other. Dietrich even leaves without capturing Galatea though hints she may try and capture her again should the Organization tell her to.
