Description:

Note used to dream of becoming a top-tier adventurer, but now he spends his days drinking away his profits at the local tavern and reminiscing about the past. Funny a boy with the Mapping ability could get so lost, huh? That’s right. Note’s dreams of becoming a big name in adventuring died the day he pulled the infamous trash-tier skill Mapping. Who wants to adventure with someone who has such a worthless ability? Wait... the renowned dungeon-diving party “Arrivers” does? WHAT?! Get your gear packed, because Note has a whole new life to navigate now! (Source: J-Novel Club)
