Luca does his best to be a mature and serious person, though he often lets his naivety and childish nature show. Luca has a bit of a crush on Jeanne, and would do anything to protect her. When Vanitas implies that he forced Jeanne to drink his blood, Luca is enraged and looks as though he’s ready to murder Vanitas.
