Nishi no Hate no Pero.

A yakuza who lived his entire life as a lone wolf is reincarnated into another world as Ryu, the third son of a noble knightly family. For the first time, he experiences the warmth of a loving family and grows up cherished. However, he soon realizes that his kindhearted family, though strong in battle for generations, is hopelessly bad at business and incredibly poor! Deciding he has no choice but to step up, Ryu first sets out to reform their finances. Utilizing his mysterious "Gokudo" skill and knowledge from his past life's shady dealings, he successfully sells the crops he cultivates. He even makes a fortune with a food stall at a local festival, launching one new venture after another. But as the family's fortunes rise, so too does the jealousy of worthless nobles who begin to hold a grudge against them.

Tarou Satu, a young man who longed for an otherworldly adventure since a child and devoted his youth to finding it, finally goes to another world on his own. However, things did not go well for him, as his previous life’s memories were about to be erased by God. Despite that, he almost dies during his reincarnation process, which allows him to fulfil the condition for a special ability and luckily, keep his old memories. From there, the now reincarnated Tauro Satu, grows up by using his brains and efforts while gradually developing his mysterious skill, Garbled Text, which everyone thought to be completely useless.
