Noroma Mahou to Yobareta Mahoutsukai wa Juuryoku Mahou de Musou Suru: Mada Juuryoku no Gainen no Nai Sekai nite, Shounen wa Banyuuinryoku no Ou to Naru

Orphaned by circumstance and burdened with an alcoholic father, Wade resolves to escape the slums by becoming an adventurer. He enrolls in a prestigious adventurer academy, enduring grueling training to graduate at the top of his class. However, during the ceremony where students discover their magical affinities, Wade is assigned "Slow Magic"—a seemingly useless ability that no one understands how to wield. What the inhabitants of this world fail to realize is that Slow Magic is actually Gravity Magic. In a realm where the very concept of gravity does not exist, Wade holds an unparalleled advantage: he remembers his past life as an overworked corporate employee in Japan. Armed with modern scientific knowledge that surpasses anyone in this fantasy world, he recognizes the limitless potential of his power. By mastering gravitational forces, he can become the strongest mage alive. Determined to harness this unique magic, Wade begins rigorous secret training. Joined by Ais, a shy girl gifted with ice magic, he sets out on a journey to conquer the unknown. Together, they strive toward an ambitious goal—transforming a despised, misunderstood magic into absolute power and making Wade the wealthiest and greatest adventurer the world has ever seen.
