The story of a hero named Fishy TSOAHNF

What else could happen when you graduate top of your class at university? A successful job? A beautiful wife? How about being reincarnated in another world filled with monsters that look as if they would destroy anything in their path?

For Fishy, he ended up getting reincarnated. But that doesn't seem so bad when you're forced to lead a village that doesn't even have one fully built house. At least he lives in a world that's filled with magic and many challenging near-death experiences.
