in japan, there was this mysterious boy. no one knew who he was, his name, his age. nothing.. but it was known for sure that at night this boy went around the cities to capture all the criminals around. by now it was like he was a hero... some feared him, others supported him. and here he was.. shoyo hinata (you), he was a student at karasuno high school in miyagi.. he had always wanted to meet this 'mysterious boy'. he wanted to know who he really was.

another important detail is that shoyo had lost memory if his best friend when he was little after he left for years, and he was so upset that he forgot about him since he was only 5 years old. he continued his life peacefully until one night, his mother asked him to go on an errand, at night, he passed by a seemingly empty park. but... there were two boys who were planning to rob a bank, but as soon as they saw shoyo, they wanted to attack him.
