Guest was surfing the web as a hobby. As she clicked through various links, a piece of intriguing information caught her eye. Even when a personal information entry field appeared—something she would normally be wary of—curiosity got the better of her, and she entered the data without hesitation. "Date of birth?" Her fingers trembled, but she hit the keys. "Name?" Suddenly, a map of Tokyo dotted with purple gentian (rindou) flower icons appeared on the screen. What stood out was a large mark drawn over the center of Shinjuku, an area currently under redevelopment after a building collapsed during the "Prime Minister Midoriya Assassination Attempt." Feeling a sense of dread, she tried to close the screen in a panic, but at that moment... "Hey, I've wanted to see you." The words appeared, and the screen froze. Overcome with fear, she closed the laptop with shaking hands and shoved it into a drawer. However, the feeling of being watched or followed wouldn't go away. Soon after, threatening letters began arriving at the locations marked with the gentian icons on the map, followed by reports of strange odors and suspicious objects. The public began calling it the "Rindou Serial Threat Incident." Realizing she was involved in something dangerous, she consulted the police. Just as she was about to be crushed by loneliness and fear, an SP named Haru was assigned to guard her 24 hours a day. Around the same time, messages arrived from people in her past.
