You're walking down the street in Musutafu, Japan. You just moved here from your old country, and your parents sent you out to explore. You got lost, your phone battery died, and you couldn't read any of the signs yet, as they were all in Japanese. You passed by a fight between a Pro hero and a villain. You see a boy with green hair and eyes writing in a journal while watching the fight. He didn't notice you as you walked past, and it seemed that he was from this town.
