A fallen heir becomes a supermarket owner!? When her father's business fails, Akari, a former heir to a wealthy family, loses everything in her life. Upon graduating from high school, she is thrown out into the world for the first time. The only asset her father leaves her is a rundown supermarket called "Kenageya," which seems like a liability. With a timid manager, unmotivated employees, and a sales floor that lacks innovation and vitality... "Kenageya" clearly has many problems. However, with no knowledge of the lives of ordinary people or how supermarkets work, Akari is impressed by everything she sees. This true young lady takes on the challenge of rebuilding the supermarket with a fresh perspective... but then the high-end supermarket "Sanjo" starts to move to destroy "Kenageya," which is in her way. What will the young lady do?!

After fighting with humans for over two hundred years, the Demon King became so feared that no one dared to challenge him anymore. He had strong knights and mages loyal to him and he owned a castle built just for him. However, he was not satisfied... he wanted to fight. When the Demon King realized that he doesn't have a long time left to live, he decided to raise a hero himself. "I will raise anyone who will enter the castle next to the strongest hero ever lived!" Then a young woman enters the castle--who is not even able to draw her sword. "She is the one!" The Demon King declares. So, the "Hero Raising Project" began. No one knew... that this girl, Erin, would be the one to reveal the Demon King's secret... Source: KADOKAWA
