Chapter 1(Introduction):

A weak young man named Kaizen Woo, 19 years old, came from a humble family. His parents had fallen into a coma, leaving him alone in a cruel world. The only family he had left was his younger sister, who was currently away, forcing Kaizen to face everything on his own.

Kaizen was often mocked by other Seekers with higher rankings. At that time, his rank was only D, the weakest in the Explorer Association.

"Yeah, that's right. After all, I'm so weak... I can't do anything," he muttered softly every time he was ridiculed, his voice filled with despair.

At that moment, Kaizen dressed awkwardly in an oversized black suit, making him look even more out of place among the other Seekers.

One day, a great opportunity came his way. He joined a dungeon exploration mission of C-rank alongside three other members:

Sung Bou, a C-rank man with a firm personality and strong confidence.

Jaen Do, a B-rank warrior known for his strength and aggressiveness.

Mikki, a girl with a D-rank like Kaizen but with a much stronger fighting spirit.

This mission was Kaizen's greatest hope to earn a higher income, covering his parents' medical expenses and supporting his younger sister's living costs.
