OVA
Description
Ren Mizusaka exists solely within cyberspace as the "Wired Ghost," a nickname reflecting her unexplained digital presence and spectral appearance. She manifests as a pale-skinned teenage girl with cyan or blue eyes and blue or lilac shoulder-length hair, often featuring spiky bangs and a ribbon accessory. Her typical manifestation wears a school uniform: a dress or miniskirt, ankle boots, and a necktie.

Her origins lie as one of five orphaned children subjected to clandestine brain-enhancing experiments. Ren's specific procedure focused on extending the duration a human consciousness could remain separated from its physical body within cyberspace. The outcome of this experiment resulted in her permanent existence as a digital entity, seemingly disconnected from any physical form. Her presence frequently bypasses conventional network security, appearing unexpectedly within secure cyber environments. She uniquely manifests virtual objects into tangible form within the digital space, adding to her enigma.

Shy, innocent, and mysterious define her personality. She initially displays significant fear towards Tohru Souma upon their first network encounter, but this fear swiftly transforms into deep familiarity and affection. She persistently addresses Tohru as "onii-chan" (big brother) and tends to refer to herself in the third person.

A profound, previously unknown connection binds her to Tohru Souma. Investigation, particularly within her own narrative route, reveals Tohru was also one of the five orphaned children involved in the experiments. His real name was Shinichi Mizusaka, making him Ren's step-brother. His specific experiment granted enhanced resistance to mental modifications like brainwashing and forced amnesia. This shared traumatic past forms the core of their bond.

Her development centers on this relationship with Tohru. Despite initial apprehension, she rapidly forms a strong attachment, viewing him entirely as a protective older brother figure. This bond drives her storyline, with Tohru actively investigating the nature of her existence and their linked history. Uncovering the truth about the experiments and their familial connection is a crucial part of revealing her background.
