Heidi

Heidi is a craftsperson working in the ink workshop of Ehrenfest, whose passionate dedication to developing new inks caught Myne's eye and led to her appointment as the lead researcher for multicolored inks. Her intense curiosity and deep concentration are such that once she enters a research state, she neglects both food and sleep and loses sight of social etiquette entirely. This near-obsessive fixation on her goals has been likened to Myne herself, making Heidi an indispensable force behind the advancement of movable-type printing technology.
