1 ~ The Twins

A military prodigy from the 104th Training Corps faces a devastating loss during the Battle of Trost. On that day, all of her comrades noticed a change in her. She became numb and cold, like the sound of her heart had slowed to a mere echo. All she focused on was training to kill. On the night of their graduation, a promise was made to their fallen comrade: To return her to the person she used to be; to restore her heartbeat.
