Possibly the Greatest Alchemist of All Time

In the capital at the Palum Slave Trading Company, a Fox-girl named Reyva who is capable of magic appears for sale, but no one buys her as she requires time-consuming training. Takumi finishes their coach and enchants it with Spacial Expansion, so the inside contains bedrooms, kitchen and a toilet. Marquis Godwin decides to increase his protection of Takumi from other nations, especially Sidonia. In the future, Akane studies the Church of Holy Light and finds they believe Goddess Anat created humans to be superior to all other races. Arriving in the capital, Papek suggests creating a second enchanted carriage as a gift for the king. With 5 days until they meet the king, Takumi agrees, so Papek arranges a private work space at the Palum Company. Sofia puts her foot down and demands Takumi find an assistant. Palum's manager, Burton, arranges for him to meet Reyva. Reyva believes Takumi will reject her too, so she is thrilled when Takumi offers to teach her and send her wages to help her mother and brother. Sidonia's emperor is furious that Barcula's king has ignored his demands concerning Takumi, and considers invading in response. Elizabeth cautions him to wait until they summon the three heroes before starting a war, and in the meantime spread a rumour about a craftsman disrespecting the church, causing their believers to find Takumi for them.
