Sekai Saikyou no Majo, Hajimemashita

When Lorna manifests an ability everyone considers useless, her family treats her as a disgrace and throws her out with no money or food. At her lowest point she discovers that her strange skill, “Internet,” is anything but worthless. It gives her knowledge from another world that can guide her toward rare materials, valuable items, and methods no one around her understands. What looked like the end of her life becomes a chance to live beyond her family’s control, and Lorna begins using that knowledge to build strength and independence no one expected, even if some of the Internet’s slang remains more mysterious to her than the hardest magic.
