Etsuko Satoda

A retired assassin currently working as a teacher at the Japan Clear Creation (JCC), teaching assassination practica. Satoda is a polite teacher who enjoys jesting opponents and speaks casually, yet matter-of-factly. She cares for her students and despite teaching them to become killers, doesn't want them to die. She taught Sakamoto, Rion Akao, and Nagumo during their time as students and still thinks of them fondly.

Even as a retired assassin, Satoda retains the skills she had in her youth. She is known for her mastery over Aikido, which she uses to redirect or nullify attacks with minimal effort.
