Mushoku Tensei: How I Became a Nuclear Bomb in Another World

One heroine: Roxy

An overworked office drone who died suddenly from working overtime opens his eyes to find himself lying in an unfamiliar alley. Above him stretches a velvet night sky, its stars brighter than any he can remember, so bright they seem unreal. His stomach growls with hunger, and his mind is now filled with all the memories of a guy named Uchiha Obito.

Wen Hao takes ten minutes to process the truth: he isn't dreaming. He has transmigrated, and it seems he's come down with a disease that will kill him if he doesn't show off. He has no intention of keeping a low profile. He worked himself to death with overtime in his previous life, and nobody is going to make him put up with anything in this one.
