Aesthetica of a Rogue Hero

Thirty years ago, the discovery of Samon Syndrome revealed that thousands of young people had vanished into fantasy worlds. The rare few who returned kept the supernatural abilities they gained there. Akatsuki Ousawa, nicknamed the "Rogue Hero," leaves his quiet life in the fantasy realm of Alayzard to seek new challenges back on Earth. He brings Miu, the daughter of the Demon King he once defeated, and passes her off as his younger sister to conceal her true origins. The two enroll at Babel, a school created for those who returned with powers from other worlds. Babel claims its mission is to train these travelers and "guide them toward the right path for humanity and their own sake," but its real intentions are a mystery to Akatsuki and Miu. As they navigate the school’s dangers, including a formidable student council, they must uncover the hidden forces pulling the strings behind Babel’s facade.
