Boku no Hero Academia: Shock Wave

Rai Kusanagi had a hard life in his hometown in the U.S. He along with six other kids were the only ones who had quirks and everyone made them feel like freaks at school. All of that changed when he moved to Japan, for better and worse. Better because his father was a well respected hero and best friends with the number one hero All Might, he felt more welcomed there, and he ended up becoming best friends with Izuku Midoriya to the point where he viewed him as a brother. But worse because his father was later killed by a villain shortly before. Now with the drive to become a hero and ensure no one else is put through the same hell as him, and also wanting to help Izuku be the next successor of All Might, he begins his journey to becoming a great hero.
He also has a thing for Mina Ashido....yes that is somewhat important.
