Chronicles of an Aristocrat Reborn in Another World manga volume 2 features story by Yashu and art by Nini.

Cain von Silford—reincarnated aristocrat with immense power and divine protection from mischievous gods—is now ten years old. He’s off to the royal capital to make his debut when scores of orcs swarm a carriage holding two young noble girls. He saves them both, and finds himself doubly engaged to be married! And then the god of commerce makes a seemingly impossible demand—one for which his magic is useless, and only his knowledge of Earth can help him achieve!
