Mofumofu to Isekai Bouken Meshi

Synopsis:

Sano Jyu, an employee of the company, was usually feeling hot inside due to his weak constitution. Then he collapses as a result of a feverish outburst and a busy season. The goddess then shows up and informs him. You should have been born in this planet, but you made a mistake. He was born with magical power in a world devoid of magical power, and that strength is what causes the fever. Thanks to the goddess's might, Itsuki is reincarnated in a different universe with a healthier body and greater magical strength than anybody else, exactly as he had hoped. And he starts his second life as an explorer with the fabled magical beast that was created from the egg that was handed to him as his companion.
