Akira Renbokouji
The younger sister of Satomi Renbokouji, Akira is a skilled hacker and hikikomori who confines herself (along with several computers) in a cardboard box in an inconspicuous part of the Academy, known only to her and Satomi.
A victim to severe bullying in middle school, she decided to isolate herself from the outside world and in doing so develops a phobia of social situations. It’s not until Shouko stumbles across her and eventually befriends her that Akira starts to open up and gradually overcome her fears.
Akira spends most of her time in front of the computer either on social media, or hacking into the school’s security cameras and students’ cell phones. She is also the one who posted the video of Haruto initially piloting the Valvrave onto the WIRED Network.
She becomes the pilot of Unit 06 in order to save Shouko, and in the process thwarts a Dorssian attempt to infiltrate Module 77 using a large drill.
