Boukun Tyrano-san

Ralph once reigned supreme as the undisputed king of all dinosaurs, ruling over a prehistoric world where his power was absolute. However, his dominion is shattered when a mysterious, massive object suddenly crashes into the Earth. Despite his fearsome strength, even Ralph is rendered entirely helpless against this catastrophic event, losing consciousness as his era comes to an abrupt and devastating end. He awakens sixty-five million years later in a drastically transformed modern world, only to discover that he now inhabits the body of a human named Mikobayashi Kana. The age of the dinosaurs has long since passed into extinction, leaving Ralph stranded in an unfamiliar era where his former glory means nothing. Overwhelmed by this impossible reality, his singular driving obsession becomes finding a way to return to his original time and reclaim his lost kingdom. Yet, as he navigates this strange new life, Ralph makes a startling discovery. He is not the sole remnant of the ancient world hiding within modern society. Other "modern dinosaurs" exist alongside him, suggesting that the cataclysm that ended his reign may have scattered more of his kind across time than he ever imagined.
