Host Security Guard

Host Security Guard is a visual novel about Masato Fujita, a security guard recruited for a suspicious experiment in exchange for a raise. His decision draws him and the people he lives with into a series of incidents.

Story

In the near future, a new district called Kayamichi has been established in eastern Tokyo. People who take security-related jobs there can receive support from the ward. Masato is one of them, living in a shared house that was once for men only. Over time, only Masato and the Kouno sisters, Sanae and Hazuki, remain, and the three are content with their ordinary life together.

One day, Misaki, a senior colleague at Masato’s company, asks him to volunteer as the subject of an experiment. Although he suspects something is wrong, he wants the raise and eventually signs the documents. The choice changes the lives of Masato and the others. He ends up working security at a suspicious research facility, where each shift feels precarious.

Characters

• Masato Fujita: A security guard who loves Sanae’s cooking and good liquor. He cherishes the shared house and the happiness of everyday life there.
• Sanae Kouno: The elder Kouno sister, gentle, graceful and talented. Though younger than Masato, she looks after the other two residents. She cooks well, is preparing for a chef’s exam and enjoys American comic books.
• Hazuki Kouno: Sanae’s younger sister. She is kind at heart but struggles to speak plainly and can be sharp-tongued. She is informal with Masato, knows how to show dependence to people such as her superior, and deeply admires and cherishes Sanae.
• Misaki: An easygoing, elusive woman at Masato’s company who often teases him. She moves between departments and can be his senior or junior depending on the situation. She proposes that he volunteer for the experiment, leaving her intentions uncertain.
