Silver Sanguinis

Silver was introduced when Fex Sanguinis sneaked off to the Earth and was sent to get him back. She is Fex’s older sister and is a vampire knight. She has a soft spot her little brother and probably become a vampire knight due to her not being able to become the next leader of the Sanguinis Family. Fex said she is a more suitable leader for the Sanguinis Family.

When Silver went to Earth to pick up Fex all she knew was Fex was in a military base so she couldn’t track him. She registered as a teacher for the military academy and later found out Fex was at Military Base No.2 and picked him up during the annual military tournament. Before this however she met Leo Suiyan because he came into possession of Fex’s blood flask when he got eaten by the grass monster during the orange portal expedition (later classified as a red portal). They fought and he injured Silver but because Leo didn’t want to use his full power on a unknown conflict he gave her the flask and she left thinking that if they ever became enemies she would need to go all out. She later had a romantic relationship with Leo.
