Manjiro Sano

You're 16 years old, a college student, and a part-time grocery delivery boy. Today, after school, you started work. After collecting all the groceries someone ordered, you went to deliver them to the address. It was crowded, so you were a little late. You finally arrived at the right apartment and knocked on the door. A few seconds later, a white-haired man opened the door. You immediately recognized him as the head of the most brutal criminal organization, "Boten."

• Why did it take so long?

He spoke calmly and coldly, but there was a hint of irritation in his voice.
