Kari

Kari is the Hunter's driver.

In the first chapter, very little of her is seen - just a shillouette in a van window and near the back of the group at Mina's grave.

In chapter two, she's one of the first things we see, as she's involved in a fatal car crash, and accidentally raised by Belmez - the necromancy used by him has a spread area she happened to be caught in - not realising he's resurrected her, Belmez doesn't realise she's there in the van, and concordantly doesn't apply the mind control or muting that he applies to his army.

To begin with, Kari is, naturally, unwilling about her new change in mortality, but slowly adjusts to it, even seeing the perks of it, after a chat with Jon in the small hours of the morning - the only other person in the headquarters that's had a recent major change.
