As the hungry girl, Noa, collapsed, her memories of a past life as a thirty-two-year-old man returned. Crying won't fill her stomach. What she needs first is food and Wi-Fi. Stepping out into the city with her small body, Noa discovers a world of dungeons and monsters. Armed with her past life's knowledge and awakened skills, she uses whatever she can. But even thinking like an adult, her limbs and stomach are still those of a four-year-old. "I'm fine on my own," insists the girl, while the adults around her can't leave her to fend for herself. A funny and desperate modern dungeon survival story, starting with an empty refrigerator.
