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

Fifteen-year-old Kurt Rockhans works as the helper of the famous adventuring party Flaming Dragon Fang despite having almost no talent for combat. When his companions throw him out in search of a stronger member, Kurt takes whatever work he can find to support himself, from construction and gathering materials to cooking and crafting.

That is where a fact Kurt himself fails to understand becomes obvious: his aptitude in nearly every non-combat field is SSS rank. Adventurer Yulishia realizes that the tasks he considers ordinary are actually beyond the level of master craftsmen and tries to make him recognize his own value. Kurt's extreme humility keeps him moving from one simple job to another, unaware that his supposedly "useless" skills are beginning to solve problems even the strongest fighters cannot handle.
