He was the Heir to the Nanami Conglomerate, and an accomplished sailor. As such, he lived a wealthy and lavish lifestyle. Pre-Stone World, He has been seen as a greedy playboy, rarely seen without the company of beautiful women, exotic sports cars, and excessive partying. While he is arrogant and greedy, it was his greed that fuelled his ambition, which was the cause of his great success pre-Stone World. He spent a great deal of time studying, and was active in ship making, from making small models, to building huge ships. The money he earned, he put toward bettering himself and the company. Senku deduced that his presence would be beneficial to the Kingdom of Science, as his greed does not only apply to himself, but to those around him. He pushes and motivates everyone.
