Dropout kara no Saishuushokusaki wa, Isekai no Saikyou Kishidan Deshita: Wakeari Violinist, Maryoku Kaifukuyaku ni Naru

Masumi’s dreams of musical stardom have long since faded, leaving her to scrape by playing violin at small part-time gigs. Her unremarkable life takes a drastic turn when she tumbles down a flight of stairs on her way home and awakens in an entirely different world. Before she can even gather her bearings, a squad of knights apprehends her, accusing her of espionage. Desperate to clear her name, she pleads her case to Arc, the stern Knight Commander, but his suspicions remain firmly entrenched until he notices the instrument she carries. Intrigued, he offers her a provisional role: serve as a musician for his knightly order until her innocence is proven. To Masumi’s astonishment, she soon discovers that music in this realm serves a vital magical purpose—restoring the depleted mana of warriors. With no other refuge available, she throws herself into the work. However, she quickly learns that replenishing a knight's magic places extraordinary demands on a musician's skill, requiring flawless precision and stamina. The true weight of her situation becomes apparent when she realizes why Arc’s elite unit has rejected every performer who came before her. They are the most powerful knights in existence, and their immense reserves require a level of mastery unlike anything she has ever faced.
