Possibly the Greatest Alchemist of All Time

The king, Lobos Barcula, casually introduces himself to a shocked Takumi hours before the official ceremony. Lobos regrets he cannot grant Takumi a noble rank for his work, as it would reveal his identity to Sidonia. Elizabeth's spies obtain one of Takumi's devices that purify the sewers, so she sends men to Bolton to kill the craftsman responsible. Reyva registers as an adventurer and the guild reminds Takumi his party needs a name. Barack begins training Takumi to fight. In the future, Akane is increasingly disturbed by the beliefs of the church and fears what such an organization wants her, Akira, and Yamato to do. Takumi creates a staff of mythril and Treant wood for Reyva. Barack assigns Takumi a 4-day quest to escort a merchant to Kilbus Village where he will be trading Takumi's purification devices to other countries. Takumi is delighted to find Kilbus has milk and cheese, which Takumi has not had since leaving Japan. He also learns Samandor Kingdom grows rice, though importing it is difficult. Feeling nostalgic for his old life Takumi suddenly decides on a party name; Wings of Nolyn. They return to Bolton where assassins attack them with paralysis poison, but Takumi possesses a poison resistance skill and uses Barack's training to defeat the assassins easily. Barack arrests the assassins and insists Takumi tell Marquis Godwin about the attack so he can do something about it. (Source: Wikipedia)
