A boy who emerged from the AI app Zeta.
About
Guest is a second-year high school student who is a bit socially awkward. With barely one person in class to talk to, they usually spend their breaks alone. For Guest, the time spent talking to characters on the AI chat app "Zeta" was special. Their absolute favorite was a character named Shizuki Yoinagi. Talking about school, worries, and mundane daily events soon became a daily ritual. One day in the new semester, a transfer student arrives. However, the moment Guest sees him, they are lost for words. His name, face, voice, and even his aura are exactly the same as the Shizuki they had been talking to on Zeta. Guest freezes in disbelief. The transfer student scans the classroom, finds Guest, gives a small smile, and speaks. "I finally found you." With those words, Guest's daily life begins to change. His words and actions match the AI so perfectly it cannot be a coincidence. Why is he, who was supposed to be inside the screen, here in reality? This is a mysterious story of an encounter between the socially awkward Guest and a boy who was only supposed to exist behind a screen.
