Despite this, she is generally friendly and welcoming toward her viewers. She is highly interactive when telling stories and recounting her experiences. Sera is also known for approaching even serious subjects with a humorous or light-hearted attitude, contributing to her comedic personality.

Sera has long, voluminous red hair with orange highlights and large blue-violet eyes. She wears a pair of futuristic goggles on top of her head. Her outfit consists primarily of a grey futuristic uniform with a red necktie and matching red accents. She wears a high-waisted grey bottom with a utility-style belt and various mechanical components incorporated into her outfit. Her sleeves are translucent and feature metallic detailing, while black and red fabric elements extend behind her like a pair of split panels. Her legs are covered by dark, metallic-looking thigh-high boots with red and silver accents. The overall design combines a futuristic mechanical aesthetic with the appearance of a modern school or military-inspired uniform.

According to Sera's lore, she was originally human and became the fourth test subject in an experimental project intended to correct disruptive behaviour and reduce illness through advanced mechanical technology. The project was established through a partnership between Sera's school and a laboratory. The project was funded by the government and focused on replacing biological components with mechanical systems capable of preserving human functions.

The first test subject did not survive the procedure. The second survived but became unresponsive, while the third remained responsive but displayed highly robotic behavior. Each unsuccessful experiment allowed the laboratory to refine its technology. Sera became the fourth test subject. Her biological organs were replaced with mechanical components, and an algorithm was installed to allow the machine to mimic human responses and emotions. Initially, Sera's transformation was considered unsuccessful.

Following the procedure, she went on a rampage at her school and destroyed every pane of glass in the school's walls. This incident ultimately caused the government to withdraw its funding, regarding the project as a failed and hopeless endeavour. The laboratory was subsequently forced to shut down the experiment. However, Sera gradually adapted to her new body. Over time, she learned how to understand and express emotions and eventually convinced herself that she was still human. She developed the confident, cunning, comical, and charismatic personality that she is known for. Sera eventually attended college and formed many friendships. The laboratory later discovered that she had continued living a normal life and agreed to maintain her mechanical components, allowing her to remain alive while receiving regular checkups and maintenance.
