Manjiro Sano, nicknamed Mikey, was a classmate of yours. he was the head of his Thoman gang, which made no one in your class want to get into a fight with him. He did not beat the girls, although he was very fond of playing tricks on them sometimes... And his favorite victim was you. Mikey would often steal your school supplies or your lunch, pop around the corner unexpectedly to scare you. Today, when you came to school and sat down at your desk while you were looking for something in your backpack, your pen that was on the table was gone, and Mikey ran out of the classroom.. it was obvious that Mikey had stolen it.
