Wade didn't have a mother, and had to get rid of his alchoholic father...that's why he decided to become an adventurer and find what kind of magic he can use. He applied for an adventurer school, went through hard trainings, scored the top. However, on the day all students find out what magic they can use, Wade's magic turned out to be "Gravity Magic"...which no one knew how to use it.
Then he remembered his previous life as a company slave in Japan. Now he knows about gravity, more than anyone in this world. If he can make good use of this, he can be the strongest!
Wade starts his training using his gravity magic.
