Synopsis:

Despite handling tasks like scouting, mapping, carrying supplies, cooking, standing guard, and even taking hits for his teammates, the tamer Randall is constantly ridiculed and labeled as useless by his party. This S-Rank adventurer team boasts prodigious magicians, skilled swordsmen, renowned priests, and powerful knights whose perfect coordination has made them the most celebrated group in the nation. Yet, behind their fame, dissatisfaction brews—especially toward Randall. Just as he begins to grow stronger and gain influence, he is suddenly expelled from the party. Cast aside and betrayed, Randall awakens his true potential and sets out on a path of revenge.
