itisanna

She said so herself in the light novel and manga that her mother died when she was in junior high. Right now she is only a freshman or a first year. This story definitely doesn't take place in the future because in a later chapter the author says that Yasuhara is 17. At most it could only be about 4 years. I doubt that they moved after her father died because Mai's family did not seem to be able to afford it because after her parents died she depended on others to raise her. She only started to live on her own after working for SPR. I also think she was capable of living on her own earlier since she already lost her father as a child. she probably had to help her mother out a lot.
