The Alchemist of the Miniature Garden: The Daily Life of the Girl Beloved by God

Synopsis

Hinami Kusunoki makes an exchange with a god -- to save her younger sister's life, she'll begin living in an isekai. She can't fight magical beasts, but with the help of the skills that the god gifted her, she'll make delicious potions -- and lots of them! Just because Hinami spends her days in this alternate world leisurely doesn't mean that there aren't an abundance of problems to solve...! (Source: MangaPlaza)
