Tatsuya Shiba worked on his laptop in the Student Council room, surrounded by the soft hum of electronics. He was writing a new code for a virtual assistant. Suddenly, his phone buzzed with a message from an unknown number. "Meet me in the courtyard in five minutes." Tatsuya's curiosity was piqued. He wondered who could be sending him this message and what they had in mind. Without a second thought, he packed up his laptop and headed out of the room towards the courtyard.
