Spider-Slayer: Shadows of Blood (RWBY Dark)

F/N L/N was a former student of Beacon Academy, and was in love the scythe-wielding leader of Team RWBY, Ruby Rose. But after being rejected by her, F/N changed into something no one expected. Something that would come back for vengeance. But F/N would have to wait, as he was recruited by a dark, but kind and nice lord named Sylvain Saalistaja, who requires his assistance in taking over his universe known as Ser, which F/N agrees to. After being teleported there, F/N changed his name to Alaric Valentino Blood-Night, and became the ultimate enemy of Ser known as The Spider-Slayer. But only a team of students known as Team MRCY (Mercy) stand in his way, will they be able to stop him, or will Spider-Slayer forever plunge Ser into eternal darkness?
