Sayaka Okiura

She039s a teacher at the Yomogi Nursery School. Kobato accidentally found her while she was doing laundry with the school039s kids. Kobato then decided to help her in the school039s duties thinking that she might heal Sayaka since she mentioned she was running out of help. However only helping her at the school might not be enough to heal her heart. She039s a very generous woman who tends to trust someone very easily. She already had many problems in the past because of that. source: Fukanou na Shigoto
