Description
Erika is described as a tsundere by her brother and Chitose. Although she cares for Ryuji the most since he's the only family left after their parents died in an accident. Sometime after that, she became afflicted by an unknown disease that causes her brain to rapidly process as much information as it normally should. She has been in and out of the hospital because of her disease. Her only option is to give a temporary relief and store most of her memories in a virtual memory storage located in the EDEN, and in turn she has access of the storage even if she's not at the hospital.

Erika gets annoyed at Chitose saying that she is "not feminine", but her behavior changed after Keisuke joined their team.
