Jack Reynolds transmigrates into the mech world and becomes a nearly scrapped mech. He is awakened from ruins by Molly Moore, whose mech compatibility is 99. However, because the mech Jack becomes has poor performance, Molly abandons him. He is then found by a pair of twin campus beauties. One twin is a mechanic and the other is a pilot, but their mech compatibility is only 6, so they are ridiculed at the academy. Jack obtains the strongest mech system. The more he fights, the stronger he becomes. He leads the twin campus beauties to participate in various assessments and tests, constantly proving the power of his mech and repeatedly humiliating Molly.
