Character: Okiura Sayaka

The teacher and principal of Yomogi Nursery, a local kindergarten where Kobato works. She has known Kiyokazu since he was seven, which is when her family adopted him. She also went to the same high school as Chitose. She is a kind and trusting person, willing to let Kobato assist her at the school even with Fujimoto's obvious mistrust of her. Upon meeting Sayaka, Kobato wishes to heal the apparent emotional pain in her heart. Sayaka is in debt due to an event in the past involving her father; in spite of this she continues to try her best at keeping the school going. Sayaka was once married to Okiura, the debt collector who frequently pesters her to close down the school. Despite having already divorced him, she has yet to change back her last name for unknown reasons.
