Vivid Red Operation Wiki

Himawari Shinomiya (四宮ひまわり, Shinomiya Himawari) is one of the main characters of Vivid Red Operation. She is Akane's classmate, but prefers to stay indoors due to a certain event. Since then, she hasn't attended school. Himawari has a tendency to be afraid of people, and she doesn't look after her appearance, leaving behind her brown locks to cover her face. She loves tinkering with machines and computers and is a super hacker. Possesses a "workshop moe" character. She is a great admirer of Kenjirou's work and fully understands the Vivid System. It is seen that she is the closest to Wakaba as she spends a lot of time with her.


Himawari is a girl of average height and has a huge breasts compared to other girls with long, wavy fair hair which goes halfway down her back. Wakaba Saegusa gives Himawari two yellow hair clips which she always wears. They have become very special to her and she says she cannot bear the thought of losing them.

Himawari was once asked to model for a magazine when she went out to a mall, and then later asked to do an official photoshoot vivid yellow .


Before the event that ultimately changed her social disposition, Himawari is a typical student of National Shin Oshima School who has been interested in technology and computers. One day, a classmate of hers, who has been suffering from online bullying, asked help from her to try and deal with her bullies by removing the anonymity function in the school's BBS system. Himawari agreed to help out in exchange for keeping the plan a secret, but the girl eventually broke her promise. Because of this, Himawari loses her trust in others and developed a reclusive behavior.

Although she no longer attended school personally since that incident, she remained a student of National Shin Oshima School, maintaining close contact with the classroom using a powerful binocular camera she designed herself. Himawari, on the other hand, stays inside the air-conditioned room of her apartment unit nearby, visited occasionally by her mother.


Hacking the Strongest Systems[]

Himawari was introduced as the mysterious girl who was able to hack into the systems of the Manifestation Engine. Kenjirou Isshiki, who has developed the security systems of the Engine itself, was baffled by this incident, so he decides to perform an investigation. His findings soon brought him to National Shin Oshima School, where the IP address of the hacker came from.

Meeting Akane Isshiki[]

During a baseball game on PE class, Himawari's camera was struck by a homerun by Akane, rendering it unusable just when Kenjirou, who is now in the form of a sea otter plush doll, stepped into the camera's sight range. Soon, Himawari receives visitors, including Akane, the one who destroyed her camera, and her friends Aoi Futaba and Wakaba Saegusa.
