Kanchigai no Atelier Meister - Eiyuu Party no Moto Zatsuyougakari ga, Jitsu wa Sentou Igai ga SSS Rank Datta to Iu Yoku Aru Hanashi

Kuruto served as the dedicated odd-job handler for a renowned hero's party, quietly managing the countless behind-the-scenes tasks required to keep the group functioning during their perilous adventures. Despite his tireless efforts, his complete lack of combat prowess ultimately led his companions to view him as nothing more than dead weight. Deeming him far too useless on the battlefield to justify his place among them, the party unceremoniously cast him out, leaving Kuruto to face the world alone and entirely unaware of his own hidden potential. What neither the hero nor the rest of the party ever realized was that Kuruto possessed extraordinary, unparalleled talents in virtually every discipline outside of direct combat. Beneath his humble exterior lay an individual whose non-combat abilities were ranked at the legendary SSS tier. From preparing exquisite meals that could rival royal banquets to constructing sturdy buildings and engineering highly advanced magic tools, his expertise defied all conventional logic. Now separated from the only group he knew, Kuruto is poised to inadvertently demonstrate his true worth, proving that the very skills they dismissed are actually the most powerful assets an adventurer could possess.
