Chisa Yomoda

She was a girl in Lain's school that commited suicide before sending a mail to all her schoolmates. As Lain, Chisa is a very introvert girl which is shown with her lack of friends and her silence. She seems to suffer from it as she is mostly evoking sad emotions. By giving up her body to live in the Wired, Chisa seemed to finally feel relieved but it didn't seem to last as, when she met Lain in the Wired, she's once again sad and quiet like she regretted her action.
