Slad is the baggage carrier for the party of heroes. One day, the hero told Slad that he was expelled from the party because he was useless as he was always just slacking off. Despite the fact that Slad had no choice but to join the party, he agreed to the hero and left the party. When he was fired, he thought to himself, “….Hmmm, I wonder if they will be okay without my Fully Automatic Support Buff? Well, I guess they’re going to be fine. They belong to the party of the hero afterall. ” His skill, the “Fully Automatic Buff”, is a unique skill that automatically significantly increases the status of his companions. That’s why the reason the heroes’ party was so strong was because Slad was there. When Slad is forced to leave the inn with no money in his hands, He had no choice but to resume his old job, and that was being an adventurer. What the hero party didn’t know is that Slad is one of the only three SSS-ranked adventurers in the world, and he hid that fact because he became too famous. Slad’s ability as an adventurer is almost the same as an ordinary person and that’s why he remained unemployed for quite some time. The reason he became an SSS-ranked adventurer lies in his another unique skill. What makes him undefeatable in battle is that he has the “Fully Automatic Debuff” skill. With this skill, whoever Slad judges to be hostile to him will become really weak no matter how skilled they are. After a while, the hero party collapsed and disbanded, and eventually the other members who had given up the hero joined Slad in his adventures.
