Tensei Nihakobinin no Isekai Kouryakuhou ( The English name is "The Strategy to Become Good at the World of Reincarnation." )

Sei has always dreamed of living life on his own terms, and when he gets a second chance in a new world, it looks like his wish is finally coming true. However, there's a twist—he's reborn as a "carrier," a class that’s not exactly known for its fighting prowess. Instead of battling foes, carriers are more about transporting goods and helping with logistics. But Sei isn’t one to be held back by his class. He cleverly finds ways to utilize his unique abilities in combat situations, proving that even a so-called low-tier character can hold their own. As he journeys through this vibrant new world, Sei not only takes in the breathtaking sights but also attracts the attention of various women along the way. With his resourcefulness and determination, he sets out to show everyone that being a carrier doesn’t mean he can’t achieve greatness. Sei is on a mission to demonstrate that even those who start at the bottom can rise to the top and make a name for themselves. So, join him on this exciting adventure where he aims to conquer the world, one step at a time!
