Rafe Lostfield is the goofiest and most reckless member of Neutron's party. He and his seven friends earned the title of heroes after defeating Demon King Xavier in the last war of the Acedia Era. But one night, Rafe suddenly woke up in a strange meadow. He was confused because he couldn't find his friends, and the atmosphere around him felt strange. His body also felt strange, and his mana flow suddenly decreased drastically. Rafe wanted to visit the nearest town to find information, but instead he was mistaken for a serial killer. Rafe had no idea that he was already in the Superbia Era, an era 2000 years away from the end of the Acedia Era. What really happened to Rafe? Where are the other seven Neutron members? Who is behind all this? Rafe wants to find out all the answers.
