The Age of Machine Gods: the Beginning of the Age of Machine Gods: the Awakening of Unit 1

In this world, everyone will awaken their mecha after the first semester of college. The probability of awakening a mecha is 70% for men and 60% for women. There is not much difference between the two. But people who have not awakened the mecha can still change their destiny by reading. After Jiang Hanyu traveled to this world, he accidentally awakened Unit 1, but was ruthlessly laughed at by his classmates. Because there are no mecha-type tokusatsu TV series in this world, and there is no Neon Genesis Evangelion, so of course we don't know how powerful Unit 1 is. There is a race living in this universe called the Skywalking Beasts, which can be understood as nomads in the universe. They like to plunder resources everywhere. One day, the Skywalking Beasts descended on the Blue Star where Jiang Hanyu is located. This is a defensive battle. But even if the "invaders" were finally driven away. So Blue Star... Is there peace?
