Luca  

, ルカ

Felicitas has been attending since she was young. Luca is proficient in the Temperance arcana and taught Felicita how to use knives in combat. In addition, he excels at household tasks such as sewing and cooking. He grew up with Pace and Debito, who are also his friends today. Despite this, Luca appears to have a strained relationship with his alchemy teacher, Jolly, whom he despises for making him and others participate in the "Tarocco Experiment" as research subjects.
