Layla functions as a lady attendant (jijo) to Marrine Kreische, identifiable by her dark green hair and violet eyes. Her core responsibility centers on delivering intimate personal support and counsel to Marrine.

She exhibits acute awareness of Marrine’s emotional fluctuations, notably her lingering attachment to Alexis Deux after the Great Hall Tragedy. In a pivotal vulnerable moment, Layla persuades Marrine to review Alexis’s unread love letters, uncovering his genuine devotion—including an elaborate romantic display of roses in Marrine’s courtyard. Layla subsequently arranges an encounter where Alexis organizes children to serenade Marrine, directly influencing Marrine’s acceptance of his marriage proposal before the Great Hall Tragedy.

Her duties expand into relaying militarily critical intelligence, such as assassination plots targeting Alexis, straight to Marrine. Her inclusion in strategic briefings alongside high-ranking Alliance officers like Aubest Meletes underscores her trusted role within Marrine’s inner circle. Records confirm her attendance during Marrine’s private reflections and decisive wartime events.
