Eren carefully placed the Two-Face Mask on the Left Guardian's face. The wooden mask began to seamlessly merge with the woman's skin before vanishing entirely.
The blood that had previously stained her face also disappeared, and her complexion was restored. Her chest started rising and falling as she began to breathe again.
Suddenly, the Left Guardian opened her eyes. The first person she saw was Eren. Her gaze no longer held the previous hostility. Instead, her expression seemed much stranger as she looked at Eren.
"Do you want to kill me?" Eren asked Kelia to test how well the two faced mask was actually working.
"How can I hurt you? You are... my master." The woman stated, her eyes being submissive when looking at Eren, as if she was an entirely different person now.
"It seems the mask is working well enough. The unique grade items are quite good," Eren mumbled to himself.
