Saikou Corp

Saikou Corp is a business conglomerate whose logo appears on various devices in Yandere Simulator.

Description
Saikou Corp is the most powerful business conglomerate in Japan. Megami Saikou is the heiress of the company.

The company has appeared many times throughout the debug builds, even as early as the October 8th, 2015 Build where the school's logo was shown on a social media page. The symbol at the center of the logo was "Saikou (最高)" which means "The Best". With arrows pointing in all directions, it means "The best at everything". YandereDev has also stated that Yandere-chan's computer runs on SaikouOS. Her console is the SaikouStation4.

After playing the final level of Yanvania: Senpai of the Night, her game will crash because the disk is scratched. There will be a console error on the screen that tells the player to visit 'www.saikoucorp.com/support' for more help. This is not a real website.

It later appeared in the December 15th, 2015 Build on the back of the laptop inside the Student Council Room, used by Megami Saikou to talk to Yandere-chan. In the February 1st, 2016 Build, the brand was shown on the camera worn by Yandere-chan if the player joins the Photography Club.

As of the April 1st, 2016 Build, there is a Saikou radio in the Computer Lab.

As of the April 3rd, 2016 Build, Yandere-chan now uses a black Saikou phone.

As of the May 1st, 2016 Build, Genka Kunahito uses a Saikou computer.

As of the May 6th, 2016 Build, a Saikou disc can be found inside Mr. Jazzy Feet's tank in the Light Music Club room, as well as a SAIKOU keyboard.

As of the June 29th, 2016 Build, several Saikou devices can be found in the Faculty Room, such as a clock, a radio, a printer, and a computer. The radio was moved inside the Audiovisual Room and made functional.

As of December 16th, 2016 Build, if enabled in Mission Mode, several Saikou metal detectors will appear in the school corridors.
