My Supermarket, His Army's Pantry

After being abandoned by her parents as a child, Taylor Stein is left with a supermarket and an overwhelming amount of debt. One day, a general from ancient times suddenly barges into her supermarket and buys out the entire store, earning Taylor a grand sum of one hundred and fifty thousand dollars, which she uses to buy herself a motorcycle. She soon discovers that the back door of the supermarket is actually a portal leading to the Norton Era.
