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 be unable to 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 is to store most of her memories in a virtual memory storage located in the EDEN.

Eater Legion
Eater Legion is the form Erika takes after being attacked by her Eater Bits. It uses Erika's memories and learns of hers and Wormon's desire to go to the Digital World. It then takes on this goal for itself, attempting to break its way into the Digital World.

Hudiemon
When Keisuke, Ryuji, Chitoise and Wormmon try to save Erika from being Eater Legion, she states it is too late and that she is fully assimilated with it and tells the boys to kill the eater. Suddenly Erika's memory banks appears as Erika, then fuses with Wormmon to create. Hudiemon then helps to kill Eater Legion and then Eater EDEN who also merges with some of Erika's memory bank data. When the World resets due to Aiba defeating Mother Eater, Hudiemon decides to stay as Hudiemon, as if she returns with Keisuke, with no Eden in the new universe - the car crash will kill her as well as her parents, rather than giving her an incurable disease. Rather than willingly being killed, she chooses to live in the Digital World and in the new universe, she no longer exists - with Ryuji as an only child.
