ガラス工房の錬金術師, Glass Studio Alchemist, Garasu Kobo No Renkinjutsu Shi

Luolight is the heir to a baron. Upon meeting Lava, a fire spirit of Salamander, he regains memories of his previous life as a glass artisan. However, even the baron’s mansion doesn’t have window glass. There’s no glass workshop—there’s not even a blacksmith’s forge. Food is scarce, and the territory is a poor, remote land where everything is lacking. Even so, in this world, I’ll become a glass artisan!
