Hitoribocchi no Isekai Hourou - Tsuihousareta F Rank Boukensha wa Koboruto Dake wo Otomo ni Tabi wo suru

Yuris possessed remarkable talent as an adventurer, yet his upbringing in a secluded village left him socially awkward and a stranger to the world. He chose to work alone, diligently hunting weaker monsters day in and day out, rather than joining a party. But certain adventurers, harboring ill will, managed to have him expelled from the guild, forcing him out of town. Alone and adrift, Yuris embarks on a wandering journey with his loyal kobold companion. It's only in his absence that everyone finally awakens to his true greatness...! A fantasy about an F-rank adventurer's incredible climb.
