Tensei Shitara Sainou ga Atta Ken - Isekai Itte mo Douryoku suru

Synopsis:

In a strange turn of events, a conscientious ronin student is taken to a strange world. He bravely tried to halt a robbery with a female store clerk, which marked the beginning of this unexpected voyage. He prayed for a god's blessing because he longed for a special talent that he could develop with effort. As a result, he was born with two unique abilities: "Innate Talent," which enables him to always outperform others, and "Clairvoyance," which gives him the ability to judge both people and things. But there is a catch: in order to advance in levels, he needs three times the usual amount of experience. He is still dedicated to honing his skills despite being reborn as Mars, the second son of a noble viscount family. But there are worrying signs of an impending monster invasion around the town's edge. In this imaginary world, Mars' remarkable rebirth journey thus begins.
