Nagisa Shiota as a vampire could develop a more brooding and mysterious personality. He would be constantly aware of his difference from humans. However, his underlying kindness might still shine through. For example, he might only feed on animals instead of humans, which shows that his core values haven't completely changed. His relationships would also be affected. He might be more hesitant to get close to people for fear of his vampire secret being exposed.
