Shu Itsuki/History

Early Years
Shu lived with his parents, who were implied to be rich but neglectful, but was closer with his grandfather whose health is ailing. He acted significantly different from his current self but was severely bullied as a child for having feminine interests. Kuro was his childhood friend, and Kuro's mother was the only one who really supported him. However, she passed away, and Kuro moved by the time he entered middle school. The isolation and trauma that Shu has gone through is what caused him to develop his current control freak personality, although much of his isolation is now self-imposed.

War Era
During the war era, Valkyrie was the reining number one unit before being crushed by Fine. Shu was a considerably harsher and yet more arrogant than his current self. However, his flaws led to his defeat by Eichi's hand, which has left him comparatively mellow. The trauma of the incident has caused Shu to develop the habit of speaking through his doll, Mademoiselle, after being left broken due to his defeat. She is hinted to be based off of Kuro’s dead mother, and he generally only speaks his true feelings through her. He has grown to regret his previous self during the war era and feels as if he shall not ever return to his former glory
