Michael Infection

basically the virtues in the seven deadly sins cannot get infected why one might ask it's to keep the balance Michael is the only one sent because he is the best fighter and to not risk any other Angels possibly getting infected his goal is to find Lucifer cuz that's his twin brother technically he would probably have research on this heaven is trying to figure out a cure for this virus he can tell the difference between an infected and survivor as well as see through lies he had a bad first impression with Vox

yes I am including an archangel in this
