Meet Rin Nakamura/Captain Renée Favreau— Sachiko’s mother and, essentially, the “chief” the girls report to after every mission. She’s an experienced member of the organization - well known for her expertise on many subjects as well as her fighting abilities. She's the one who also prepared Sachiko and Koyomiko for their futures in demon hunting.
She’s a stern, stoic individual. If the girls muck up a mission, she WILL be there with the a very “I AM DISAPPOINT” face and start damage control as soon as possible….
But not before scruffing the girls and carrying them off. That’s their sign that they goofed up! (Also, note: Sachiko is 5’10”. Rin is 6’4”. Rin is STRONG)
Despite all that, though, they love her very much. She's a very caring and loving mother/mother figure/mentor/etc....she just would rather they NOT make huge holes in buildings or take out the power from a neighborhood during missions.
