Madougu no Shuuriya Hajimemashita

Setsu is a high school girl summoned to another world. But it seems that she was just caught up in the hero summoning! She gets banished from the royal castle for having no talent. She somehow manages to start a life in the royal capital, but living on her own for the first time is tough. She fails at her job, the bathroom is filthy, and the food tastes terrible! But then she discovers she possesses the super-rare talent "magical tool artisan"...!? (Source: Kadokawa, translated)
