Here is Air Air is a vampire who is 69 years old. But looks at least 17 or 18 years old. He is an agent of the BFC, or Blood Forge Crusade. He saved Diablo from the NS 12 years ago. Diablo is now 15. Vampires can't drink human blood because it makes things worse. So they use Blood Powder. Which is powderized cow's blood. When touched by water it turns back to its bloody form. The smell isn't bad but the color returns. However for Air it makes him sick. So Diablo is letting Air drink his blood. Later on they become a couple. Which isn't bad at all ^^. He travels along with Diablo to get rid of the NS. To find out more info about the NightSlayer story go to me website http://www.freewebs.com/brokensouless/ Next is Hikari Subuhara.
