Astolfo Granatum is a side character in The Case Study of Vanitas. He is a teenage boy who is a Chasseur Paladin, as he holds the seat of Garnet. He’s easily enraged and claims that he wants to kill every single vampire in order to cleanse the world. He is the youngest paladin in history at the age of fifteen.
One day, he wasn’t able to kill a young vampire who had been hunted down by the Chasseurs, leading to his family and him being abused for days on end by a group of vampires. His mother was violated in front of their eyes, then had her head split open. His father died, too. Astolfo and his sister, however, survived longer and forcibly got their blood sucked over the course of several days, being marked by thirteen vampires in the process. He held his sister’s hand while she died and swore that he would kill every single vampire, while also screaming for help. Eventually, he is saved by Roland who kills the young vampire and makes Astolfo admire him in a heartbeat.
