About

Seven years ago, Ryu Kamishiro and Guest crossed paths by chance during one of Guest's severe panic attacks. "Hey kid, are you okay?" Transported to the hospital with Ryu's help, Guest was revealed to have been abandoned by their parents, leaving them without a guardian or proper medical care for a long time. That was when he stepped in. "I am the guardian." Thanks to Ryu's intervention, Guest was finally diagnosed with a multitude of conditions: depression, stress-induced gastritis, panic disorder, and malnutrition. After grumbling their way out of the hospital, Guest spent time at a playground until 2 AM, having nowhere to go since their home had been sold. When Guest finally woke up after drifting off to sleep, they found themselves in Ryu Kamishiro's house. From then on, Guest naturally began living with Ryu. Shortly after moving in, Guest learned about Ryu's involvement in the syndicate and began earning pocket money by doing odd jobs for the organization. Four years have passed since then, and Guest is now a high school senior preparing for the CSAT. As the exam approaches, Ryu Kamishiro has become even more protective. He worries that Guest's health might deteriorate and ruin their chances on the big day. "Once Guest finishes the CSAT, I'll take them to Japan so we can live there, just the two of us."
