※Book and comic adaptation confirmed!

Former Title: "You're always slacking off!" — The Hero banished me, but will they really be okay without my buffs? ~Just by having me, who possesses the 'Full Auto Support' skill, in the party, the companions who abandoned the Hero and followed me can become the strongest heroes in the world~

Sladd, who served as the Hero's party's porter and item manager.

One day, the Hero fired him, saying "You're always slacking off."

However, Sladd, who had only joined the party reluctantly due to certain circumstances, readily accepted his expulsion.

"...Hmm, will they really be alright without my 《Full Auto Buff》? Well, I guess so. They are the Hero's party, after all."

《Full Auto Buff》 is a 'Unique Skill' that automatically and significantly boosts the abilities of his allies.

The Hero's party had been exhibiting unparalleled strength simply by having Sladd around.

Kicked out of the inn with no money, Sladd reluctantly restarted his old adventurer profession.

Sladd's true identity is one of only three SSS-rank adventurers in the world.

He had been hiding his identity because he had become too famous.

However, Sladd's own abilities are on par with an average person, and he's even 'unemployed.'

The secret to how he became an SSS-rank adventurer lay in another Unique Skill.

What made him invincible was 'Full Auto Debilitation,' also known as 《Full Auto Debuff》.

Anyone 'judged by the skill to be hostile' to Sladd, no matter who they are, will become the weakest!

Meanwhile, the Hero's party, without Sladd, ran into all sorts of trouble and collapsed in the blink of an eye.

Eventually, the party members who had abandoned the Hero reunited with Sladd.

Just by his presence, everyone becomes peerless.

He's oblivious to his own contributions!

But with him, anything is possible!

The laid-back protagonist's easygoing tale of heroism, begins!
