Lugner-sama, you get angry when I disturb you, don’t you?
One of Aura the Guillotine's executioners, she is good at detecting magical power, and her unique magic is the imitation magic "Erfassen". By memorizing the flow of magical power within a person's body when they move, it copies the other person's movements and reproduces them on its own.
She also summons various weapons from the void, including a battle axe. In the original story, she also wields a broadsword, and in the anime, she also carries a spear and a throwing knife.
When she confronts Stark, she imitates the techniques of his master Eisen, whom he once witnessed and who he calls the strongest warrior.
However, Stark saw that her attack was much lighter than Eisen's actual technique, and after creating an opening with his plan to receive the ax's horizontal strike with his abdominal muscles, he used all his strength to attack Linie. Linie was defeated and died after being hit by the vertical slash "Lightning Strike".
