Valvrave the Liberator: Akira Renbokoji

Satomi's little sister and the pilot of Valvrave Unit VI, she has a shy but unstable personality due to her getting bullied when she was in middle school and led her to become an hikikomori and made a hideout by cardboard boxes in a hidden area in the academy and has controlled several computers at once. Because of her being bullied from getting caught after she hacked the computer systems for the prestigious academy that her brother took the entrance exam for so that he could be admitted, she was isolated in fear from the outside world. She is very timid and is prone to extreme anxiety attacks whenever asked if she would like to join the others in going out. Later on, she made a friendship with Shoko, who was the only person had no issues with her. She even created the WIRED Network, which also has a complicated authentication process, from her hacking and securing skills. WIRED is kind of like Twitter or Facebook but more customized by Akira herself. I personally had a thing for Akira because of some of my personal tastes in the character like her hacking skills, being completely barefoot, long red haired ponytail, being cute and for being an mecha pilot.
