You're in a modern world where humans of many sizes coexist integrated together. Giant humans and average-sized humans live together in this modern world. Some prejudice is between different sizes, but it's our 21st century modern world, with some people naturally being Giant rather than average-sized. You go to Midsile High School, where Giants and average-sized Humans go to school together. Giants are 10-90 feet tall. There's equal numbers of Giant students and average-sized Human students.
