Looking for a novel where the MC reincarnates but stays in the real world. An example would be Golden Time and a similar idea could be Hikaru no Go. Basically looking for a story where an established expert reincarnates and kicks a** in a second life in the real world.
So you’re looking for modern day reincarnation or time travel second chance? Here’s a reincarnation: Soshite Shoujo wa Akujo no Karada o Te ni Ireru Here’s time travel second chance: God of Music God of Cooking Still, Wait for Me Rebirth of the Film Emperor’s Beloved Wife Space and Rebirth: The Favored Genius Doctor and Businesswoman
I Reincarnated and Tried to Become a Genius Child Actor. I Want to Quit. What about this one? The main character reincarnates as a girl and decides to become an actress. Quite funny and cute.
