Dokushin Oji-san no Isekai Life: Kekkon Shimasen, Free na Dokushin Koso Saikou desu

Oda Gentoku is a skilled handyman who operates a modest odd-jobs shop in his local town. Living entirely on his own terms, he embraces a relaxed and carefree lifestyle while proudly declaring his lifelong commitment to remaining single. For him, the freedom of bachelorhood is not merely a circumstance but a personal philosophy he happily defends every day. His peaceful routine takes an unexpected turn during what should have been a standard electrical repair job. A sudden accident leaves him electrocuted, and instead of meeting his end, he awakens to find himself transported into an entirely different world. Stripped of his familiar surroundings yet retaining all of his practical expertise, Gentoku faces this strange new reality without panic or hesitation. Rather than seeking out grand adventures or romantic entanglements, the steadfastly single middle-aged craftsman simply decides to resume his trade in this unfamiliar realm. Armed with his dependable skills and an unwavering dedication to his independent lifestyle, he sets out to build a comfortable existence from scratch. This is the story of a man who proves that true happiness requires no attachments—only the liberty to enjoy a quiet, self-directed life as a master handyman in another world.
