URA KAGYOU TENSEI: MOTO GOKUDOU GA KAZOKU NO TAME NI RYOUCHI HATTEN SASEMASU GA NANI KA?

Description

A gangster who has lived all alone is reincarnated into another world as Ryu, the third son of a knight family.
He grows up receiving the love of a family he never had the chance to be with, and then he realizes something.
His kind-hearted ancestors have been good at fighting but weak at work, and they've been an extremely poor family for generations!
He decides he has to do something to help, so he starts by reviewing his finances.
He then uses his unknown skill, Gokudo, and his knowledge of the underworld from his previous life to sell the crops he has grown, and on top of that, he makes a stall at a festival a huge success, and gets one new business after another on track.
However, a thug nobleman appears, who holds a grudge against the Ryu family for their rapid growth...
A fantasy about a kind-hearted ex-gangster boy's sense of duty and compassion as he manages his territory begins!
