Chisame isn't a typical nerdy girl. Her harsh attitude is her way to keep people away, as she's afraid people will find out her secret. Her shortsightedness is the result of her early interaction with a computer and internet at age 3. Online, she gained fame as a competent hacker and has a side job as a "pen tester". She has some mischievous side. as sometimes she will modify some data at her school for fun.
