Lyudmila Andreyevna Ruslanova, nicknamed Milasha, hails from Orussia and serves in the Orussia Imperial Army. She is assigned to the League of Nations Air Forces Aviation Magic Band, a non-combat unit focused on boosting morale through music, accompanied by her familiar, Olivier.

Milasha's personality swings between extreme energetic highs and lows, consistently mirroring her surroundings. Her natural intensity and caring nature often make her unintentionally come across as frequently upset, despite no desire to appear angry. She secretly pens poems in her flight log, revealing a creative streak. Within the unit, she shares a friendly fashion rivalry with Virginia Robertson, her own style noted as unconventional.

Functionally, she handles vocals and lyrics for the squadron's performances. She operates AT-6 Texan Striker Units, a Liberion-made trainer aircraft also known as "Harvard" within the Britannian Commonwealth. She possesses a noted sensitivity around her ears.

Her background involves joining the music squadron after being assessed as unsuitable for frontline combat, alongside other witches facing similar challenges, finding an alternative purpose here. Her interactions bolster group cohesion, particularly during collaborative efforts like songwriting. Advice to compose songs for someone dear helps her and the unit forge emotional connections through their music.

Character development unfolds through the unit's shared journey: progressing from shaky beginnings in basic flight – initially resolved by holding hands for stability – to independently mastering complex aerial choreography. This growth signifies both enhanced operational skill and strengthened bonds. Her archetype is Lidiya Andreyevna Ruslanova, the renowned Soviet folk singer, aligning with her musical role.
