Jade

Zombie/vampire hybrid myth, he's friends with SAM as well, he's got those sleepy eyes. He's a senior at the school they go to, but is very rarely ever actually seen on campus. Most people don't like his vibe for some reason, despite him being very easy-going and nonconfrontational. He suspects its due to being part zombie. Basically "adopted" SAM and Keiji when they first showed up at the school, and he's teaching them to be normal teens.
