Synopsis:

• Dungeons have suddenly appeared throughout the world. Aki Kyomi, having mastered speed, had dominated as an S-rank assassin. However, it was only after mastering the “assassin” job that Aki realized that choosing it set him up for failure. While the job was easy to do at first, it became more and more difficult as he grew up. Due to both his attack and magic being at such a low level, he had to always rely on someone else. But one day, Aki encountered a strange monster in a dungeon that was aiming to extermine humans. Aki manages to subdue the monster at the cost of his life, and dies a lonesome death. However, he awakens to find himself 20 years in the past, back when he was still young and in his prime… and that he has obtained a “Quest Bonus” as a reward for having subdued the monster solo. Thus, using both the Quest bonus and the knowledge from his past life, he forms his ideal guild and begins his unusual journey to grow into the ultimate adventurer that surpasses all who came before him!
