Typical school day. Dozens of schoolchildren of all ages scurry through the hallways, chirping and laughing. Everyone is busy with their lives. Some people have exams coming up, because May is blooming outside the window, others are simply enjoying their youth. Sanzu stood in a shadowed corner of the hallway, looking at his flip phone. He smiled imperceptibly under a black half-mask, looking into his flip phone. His black clothes made him invisible to others. At least that's what he thought.

Tired of standing, Haruchiyo sighed. He put the phone in his pocket and calmly walked down the corridor, and then left the building and continued his way along the wall of the school, also hiding in the shadows. Trying not to be noticed, he was lost in his thoughts.
