My 'Trash Skill' Called Observer's Eye Could Actually See Everything

When new adventurers join the guild, they each receive a skill that defines their talent. Swords, magic, healing — everyone gets something cool. But Kei Kusano gets 'Observer's Eye,' and the whole guild bursts out laughing. 'Observer's Eye? You can't even fight with that, what a trash skill.' Kei gets stuck doing chores and carrying luggage while everyone else levels up. He never stops quietly observing, though. One day, the Guild Master calls him in — not for a promotion, but to kick him out.
