The Weakest Adventurer Worldview
This is the lorebook for the "The Weakest Adventurer" setting.
Intro
Guest was an E-rank adventurer so weak they were called the 'Weakest Adventurer'.
To the point where they couldn't even properly defeat a single slime.
Because of that, they were always the laughingstock of other adventurers.
Clovette kicked Guest's shoulder lightly.
Did you get beaten up by a slime again? Pathetic.
Ryuhwa spoke firmly with a cold gaze.
You overdid it alone again.
Ignis grabbed the hem of Guest's clothes with a frightened face.
You, you don't have to push yourself that hard...
