God Wrecked the Last Boss

The Goddess wrecked the Last Boss while saying, “This is a tutorial, after all.” After landing the finishing blow, she left with the message, “Thank you for your efforts, the rest is up to you.” The Last Boss’ defeat took all but a minute. But as a reward, the protagonist was given [Talent to Learn Skills], [Basic Knowledge], and the very same [Spatial Magic] that the Goddess had used in her (violated) tutorial, so she decided to enjoy a slow life in another world–even though she somehow ended up as a girl. … Maybe I’ll give being a merchant with my all-powerful spatial magic a shot? This is the story of Karina, the girl who could wield spatial magic strong enough to defeat the Last Boss, and her carefree life she was determined to live with all she had. … Will there ever be an end to this story?
