Seri

Seri is the leader of the Vampire Hunter Group.
Both of his parents were hunters too, so he naturally followed in their footsteps.
He is overly serious and devoted to his work. He can make the calmest decisions about things and will not do anything he deems pointless.
On first glance he may appear to be calm and intellectual, but he quite often gets emotional.
He believes everything that happens around him is his responsibility.
