I am looking for an anime/manga that I forgot it's name. i Remember a college guy and a girl fighting a shapeshifter army with black tuxedo's and glasses. I also remember that the boy's name was chunn/sean and the girl was name ruri but these I flos are super flou. please help. thank you. this manga/anime was in the early 2000-2005

School Shock (Chu Feng) seems to have main characters named Lui Li (Ruri) & Shun Hao Xuan. But it's from 2009. I've never read it but it seems to have fighting in it. And there was an anime of it too.
