I Don't Believe in Gods, But I'll Manipulate Divine Miracles ~Intending to Overpower the Other World by Increasing My Magic Arbitrarily~

Waking up one morning, I find myself in an unknown place, and to my surprise, I've become a child! This world has magic called "Divine Miracles." I'm possibly the only one who realizes the limitless potential of this magical power. So, I'll live a fun and exciting life using this power! However, the magic I secretly learned leads to suspicion. A commotion erupts in the small village of Rish, and I'm sent to a local magic academy. While attending the academy, I take a step toward becoming an adventurer, but I get involved in the kidnapping of a marquis's daughter, play with curses, and dream of striking it rich with alchemy. After graduating from the academy's junior division, I go to a magic academy in the capital. There, I'm called a prodigy, earn a grand title as a "Curse Breaker" by making money with curses, and start living with two girls. I face various events, from dealing with a fake "Curse Breaker" to almost being murdered by the church. I get engaged to three girls, succeed in creating Orichalcum through alchemy, and secretly become a billionaire. I'm given a medal for military service, but suspicious people appear, hinting at a storm involving the entire country. A war breaks out between the kingdom and the empire, the capital is attacked, and a rebellion occurs in the empire. Who becomes the new emperor? The story follows a boy (who is actually an adult in his mind) as he gets caught up in a conflict between two major powers while dreaming of a carefree adventurer's life. Note: It takes some time before he becomes overpowered, as the story also depicts his growth process.
