Merel

Merel is a soldier from Creus's squad

Merel is a 16-18 year old girl with short light brown hair and green eyes. She is insecure and cowardly, ready to flee at any danger. She is very afraid of war, despite being a member of Creus's squad.
She wears a long white dress, a short lilac cloak, glasses on her head, high boots and binoculars.
She is a member of Kreius's XII squad and a former SPD apprentice. In these later chapters, she befriends Charon, Marsha, and Sergei.
Merel was accepted into the St. Pavlov Foundation as a young child after being orphaned during the Tempest, and was educated at the School for the Primary Defense of Humanity (SPD). Although she was in the same class as Vertin, Matilda, and Sonetto, she wasn't particularly close to them. Merel preferred to spend her free time reading in the school library. She eventually learned to shapeshift from a book called "Fiddler Crab Transformation for Dummies."
Even as a student, Merel preferred to remain in the shadows, going so far as to deliberately plan to graduate last in her class to avoid attention and the job search, so she could escape and live a normal life. Her plans were shattered when Kreius decided to invite her to an internship at the Vigiles Bureau and later to join Squad XII.
XII detachment
While serving in the XII Squad, Merel received the code name "Blackbird".
While at the front, Merel briefly meets Marsha. She later also meets Charon, whom she asks to join their convoy heading to the front.
After completing her task of distributing Foundation-issued rations to the soldiers, Merel discovers Charon sitting alone in a corner. She approaches him and tries unsuccessfully to coax him to eat. However, she discreetly slips some rations into his coat pocket. When Charon stands up and tells her he needs to leave, Merel offers to go with him. He declines.
