Homeless Tensei: Isekai de Jiyuu Sugiru Jikyuu Jisoku Seikatsu

Shinichi Tanaka was once the representative director of a major corporation, but his fortunes eventually collapsed, leaving him entirely destitute. Stripped of his wealth, career, and family ties, he is reduced to living on the streets as a homeless man with nothing left to lose. On one particularly bleak, rain-soaked day, a sudden bolt of lightning strikes him down, abruptly ending his miserable existence in the modern world. Instead of death, Shinichi awakens in a strange, unfamiliar realm, discovering that he has been transmigrated into another world. Even more astonishingly, he finds himself inhabiting the body of his twenty-five-year-old self, granting the fifty-six-year-old man a miraculous second chance at life with the vigor of youth. Thrust into this mysterious new environment without any prior connections or resources, he must navigate the unknown dangers and wonders that surround him. What follows is a turbulent and unconventional adventure as a seasoned former executive leverages his lifetime of experience to forge an entirely independent, self-sufficient existence in a fantastical world unlike anything he has ever known.
