The Reincarnated Youngest Prince

Hirano Aito, a name literally EVERYONE knew about. He was the founder of the largest corporation Ocean corps. He died from getting shot by his relatives, I mean how would they expect the toddler they left to fend for himself turned out to be a genius and unexpectedly controlled the black market too (they found this part by accident). Though, getting reincarnated as a baby was NOT part of the plan. He became even more confused when he found out he was born in a world filled with magic as the youngest prince Louis Kalle Rothschild, of the Ruixotia Kingdom. With his past life knowledge as a genius, how will he live as the youngest prince?
