Shiori Sasaki

Shiori is Kaori's mother and works alongside her husband as a researcher at the International Science Institute. Entrusted by her close friends — Kanade's parents — she welcomes Kanade into her home as a guardian figure, offering warmth and understanding in everyday life. However, when either Kanade or Kaori steps out of line, Shiori's legendary lectures — lasting several hours — make her the most formidable authority figure in both children's eyes.
