Serial Experiments Lain starts with Chisa's suicide as she falls from a roof, her body is crushed by a falling building sign. Before jumping, she looked peaceful.

Some days after, each students for her school receives a mail from her after her death. Lain responds to it which initiate a chat with Chisa. Chisa explains that she didn't die but have just abandoned her flesh. She wanted to show everyone what she did. As Lain tries to understand why she killed herself, Chisa answers "God is here."

After that, Chisa will appears mysteriously to Lain trying to convince her to follow her. The first time on her way back to school and second time during her class and the last time when Lain plugs herself to the Wired. The last time, Lain remembers having walked with her from school one time, she thinks that Chisa decided to contact her as a friend but as she talk to her Chisa doesn't answer and shows a sad face before disappearing once again.

When Lain "reboots" the reality, Chisa can be seen still alive going to school. We learn that Chisa seems to have taken Lain's role in this reality as Alice tried to invited her to going out with her at the Cyberia but she was too shy and decline the invitation (the exact same scenario happened to Lain during the first episode).

Personality
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.

Lain
Chisa went to the same school as Lain and both are in the same class level, one day they even went back from school together. After her suicide, Chisa sent mail to all her school including Lain. Lain responded to the mail and started to chat with Chisa about the Wired. This chat launched Lain's interest to the Wired. After the chat, Chisa appeared to Lain several times, one time trying to explain to her why she killed herself.
