Oharaibako no Tensai Fuyojutsushi wa, Henkyou de Yuuyuu Jiteki ni Kurashitai: Bannou Fuyujutsu de Kizuitara Henkyou ga Sekai Saikyou no Kaiteki Kyoten no Natteita

"I'll teach you about the pride of a craftsman." Ryuji, an enchanter, was kicked out of his party for being useless and unable to fight. But this man's magic stones are extraordinary! Not only do they enhance abilities, but he can also create golems with the magic stones he enchants, and turn barren land into farmland overnight, making his new home in the frontier a comfortable base! His skills, his style, his values—all unleashed without restraint! Eventually, his skills reach even the royal family...? This is the story of an all-powerful and strongest enchanter who will make the world know the pride of a craftsman!
