Secret Side Business Reincarnation: Former Yakuza Expands Territory for Family, But What?

A man who has lived a lonely life as a yakuza is reincarnated into another world as Ryu, the third son of a knightly family. Growing up surrounded by the love of a family he never had before, he soon realizes that his kind-hearted relatives have been poor for generations due to their strong fighting abilities but weak business skills.

Determined to make a difference, he utilizes his unknown skill “Gokudou” and his knowledge from his past life in the underworld to create and sell coffee, chocolate, and hand-pulled carts. He improves the harvest yields of their fields and establishes a thriving stall at a local festival, successfully launching one new venture after another.

However, as he steadily expands their territory, the family faces danger from resentful nobles who dislike their growing influence. Will they be able to overcome these challenges and secure their newfound prosperity?
