Rebel Seoul by Axie Oh

After a great war, the East Pacific is in ruins. In brutal Neo Seoul, where status comes from success in combat, ex-gang member Lee Jaewon is a talented pilot rising in the ranks of the academy. Abandoned as a kid in the slums of Old Seoul by his rebel father, Jaewon desires only to escape his past and prove himself a loyal soldier of the Neo State.

When Jaewon is recruited into the most lucrative weapons development division in Neo Seoul, he is eager to claim his best shot at military glory. But the mission becomes more complicated when he meets Tera, a test subject in the government’s supersoldier project. Tera was trained for one purpose: to pilot one of the lethal God Machines, massive robots for a never-ending war.
