Darker than BLACK
A man stands at the lip of a rooftop, poised to jump. As police rush towards him, he begins to glow mysteriously, and flies off into the sky. Unfortunately, despite his cop-dodging abilities, his landing is rudely interrupted when a masked being ends his life. Apparently, a decade before the start of the series, an ominous wall appeared in Tokyo. Called Hell's Gate, it ushered in the appearance of Contractors, emotionless people who have superpowers but no emotions, and Dolls, spirit mediums created in someone's likeness. The episode pauses there to introduce Li Shunseng, a Chinese student who has just moved to Tokyo for school. Of course, he's not really who he claims to be, and he seems to have a knack for running into trouble, but at the very least, he seems to be able to hold his own against Contractors.
