Vamper is a Vampire and a member of Ayakashi. He was teamed up with Toutan.
Vamper has spiky purple hair and purple eyes. He has a lot of tattoos and piercings. He wears a purple and black stripped shirt with a white vest and brown plaid pants.
Vamper appears to be cruel yet laid-back but is actually quite impulsive, short tempered, and violent. He doesn't like to fight battles that with opponents he finds weak and usually likes to finish them off quickly. But he also can help his foes; when Lavi ask him to carry everybody out Necropolis, he accept.
He first appeared with Toutan trying to steal the sacred treasure. He ends up fighting Blue. He then shows them that he is made up of a bunch of bats so he can't be killed. He easily beats Blue and goes to kill Keel and Lavi. But then Blue gets back up and reveals his true form. As they battle Blue uses a strong attack and Banpaa turns into a Bat to escape. He and Toutan decide to leave because they dont want to deal with Keel and Blue. As the two leave Banpaa is chased by Toutan for saying he is stronger.
Vamper and Toutan later appear in the desert, where they wake up Keel who had earlier passed out from exhaustion.
