As a member of the "Nine Road" for decades, I've traveled the world preventing global catastrophes. My long-awaited retirement was finally within reach. <br><br>At 56 years old, what awaited me was the fame of being a battle-hardened veteran who had reached the highest EX rank, and countless accolades as humanity's hero and Earth's guardian! <br><br>All that was left was to truly enjoy a life of wealth and glory! And just as I was about to settle into a comfortable retirement...<br><br>"Aaaargh! This can't be happening!" <br><br>I woke up to find myself as my 24-year-old self from 32 years ago! Even worse, I'm back in the past when I had absolutely nothing!!!<br><br>"I wasn't supposed to be the regressor!" <br><br>Moreover, Nicholas from the Nine Road was meant to be the returner. Does this mean I have to gather the Nine Road myself from scratch? <br><br>A life forced to start over as an unexpected regressor! This time, I'll finish things quicker and try to enjoy life.
