Aaron, who disguises himself as an ordinary academy instructor, is actually the heir to the Humerlinde family and the number one heretic on the Holy See's heretic list. Under the name of God, the Holy See massacres other races and monopolizes power. Unable to tolerate it any longer, Aaron publicly tears off the Church's hypocritical mask. Armed with an ancient magical bow, he is accompanied by powerful allies, including Ivy, the Elven Queen, and his alchemist butler. Together, they sweep aside the Judgement Knights and cardinals, crushing strongholds of the Holy See such as the Blood Moon Monastery. He rallies oppressed heretics from across the continent, ventures into an ancient temple to seize its source power, and confronts the Pope and the false god. With overwhelming strength, he shatters a thousand-year-old yoke of divine authority, vowing to overthrow the tyranny of the Holy Light and establish a new world where all beings are equal.
