Erika Mishima (御島 エリカ Mishima Erika?) is a character in Digimon Story: Cyber Sleuth - Hacker's Memory. She is the younger sister of Ryuji Mishima and also a member of the Hacker Team Hudie. Her Enjoy! Chat avatar is a Morpho Butterfly named Bu773rfly.


Erika wears her Blue Hudie coat like a cape while sporting a yellow, thigh-length, sleeveless dress with frills underneath. A small plush whale named Toto sits on her coat's left shoulder and uses big whale plush named Memetan that acts as her keyboard.


Erika is described as a tsundere by her brother and Chitose. Although she cares for Ryuji the most, since he's the only family she has 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 more information than it normally should and she has been in and out of the hospital because of her disease. Her only option is to get temporary relief by storing most of her memories in a virtual memory storage located in EDEN, which she always have access to.

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

Other forms

Eater Legion

Eater Legion b

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 vg

Hudiemon is the resulting form of the merging memory data of Erika and her partner Wormmon in a Champion level Digimon with humanoid appearance and butterfly features that solely gives the essence of their Hacker Team Hudie.

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. Due to her becoming a Digimon, Erika's actual data were transferred to Wormmon as a whole and making the latter as a new vessel. 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 in this form, as if she returns with Keisuke, with no EDEN in the new universe - the car crash will badly hurt her and her parents, with only the latters surviving from the accident, after she will not be able live much longer giving her 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.

It has some significant process to Biomerge Digivolution since; (1) The Tamer and Digimon are on their digital state, and (2) It is only possible to do inside the Digital World and we can call EDEN a Digital World but also in term a man made.
