Akari Hirai is a young woman who grew up in a farm, during the time before Morioh started growing. Once it started to, she moved into the town, with dreams of living bigger then her old life. She soon becomes romantically involved with a coworker who is quite charming, and earns quite a bit in the company. Everything changes though once a woman calls her, informing her that lover is in fact sabotaging buildings throughout Morioh for financial gain. When she comes to roof of her work to confront him. She is pushed off and trapped between 2 buildings. She cannot call for help, as no one can hear her voice. And she can't get out as both exits are shut off to her. Her former lover Teruhiko promises her he'll release her. If she tells him where she's hidden his money from the sabotaging.  But she believes that he's lying.

Akari will not give up though, she is determined to find a way out of this space. And better her life. 

I have no real idea of Hirai's voice, other then it's medium high, and that she's tough yet vulnerable. She feels doomed at times, reflecting on her past mistakes. But is given small hopes to keep her going!
