Now, he needs to share a body with a moron while trying not to get killed by kingdoms, crime syndicates, and other organizations. All the while, he builds a revolution of street children from the ground up and dabbles in alchemy. Come along as Res tries to cling to his dream of a carefree life despite more and more responsibility.
