Neeya (ねえや, lit. big sister) is Oboro's childhood caretaker who appears during the flashback of episode 16. The two had a close mother/daughter relationship and after she died, Oboro would frequently go to her grave to pray for guidance and strength. Her character design was based on Kuzuha Kuyou, one of the characters of Masaki Segawa's other manga series . There are hints she may be Oboro's biological mother. Her name is unknown.
- (Upon being asked if Oboro is her daughter) "Perhaps there was a time when we had such a bond, but those memories have faded."
