Fanatics of the Magic Academy

Rose arrived in a Western fantasy world. Good news: he was a fanatic, and a holy son. Bad news: magic reigned supreme in this world; those who worshipped gods were burned at the stake. What the hell?! Is it too late to switch to magic now? Just as Rose was trying to figure out how to leave the cult, he discovered things weren't so simple. What did it mean that the mastermind behind their cult was actually a high-ranking magician? What did it mean that fanatics who worshipped angels would grow wings, and fanatics who worshipped dragons would become dragon girls, and that these perverted upper-class figures preferred this? What did it mean that it was easier to become a fanatic? What did it mean that my parents didn't actually love me, and that raising me into a fanatic was just to make me a toy for the upper nobility?! Is this…right? In a world under absolute magical rationality, everyone was considered expendable. Ordinary people, with the slightest carelessness, would fall into the "kill line" and quickly become research material in some magician's laboratory. Those at the bottom could only survive by being extremely cautious and exploited to the extreme. The only way for ordinary people to change their fate is to take out huge loans to attend a magic academy, where all magic books use extremely obscure and difficult language to build incredibly high barriers to knowledge. Even the high and mighty magicians cannot escape this structural suppression and alienation. ...Everything in this world is eroding Luo Xin's sanity. [Your sanity has collapsed, but your faith grows ever more fanatical.]
