Otome Game no Heroine de Saikyou Survival

Alicia loses her village in a monster attack and endures three brutal years in an orphanage before finally escaping. During her flight, an older woman tries to kill her, but their struggle brings Alicia into contact with a strange crystal that floods her mind with unfamiliar knowledge, including a shocking truth: she was meant to be the heroine of an otome game.

Disgusted by a future written for her by someone else, Alicia refuses to follow the assigned story. Using the knowledge she has gained, she learns to fight and survive alone in a world far too cruel for a child, deliberately shaping herself into a strong, calculating girl who will choose her own path at any cost.
