Neptune Sakuma. Born as the child of Kai Sakuma, a researcher of all things odd. Her mother died while giving birth, so no one could stop Kai from doing whatever he wanted to their child. Neptune was experimented on her entire life, and when she turned 16, a DNA experiment took place that sharpened her teeth and made them similar to that of a shark. She wears a mask, and after machine blew up and the luck of "that person" got Kai ran over, Neptune took his lab coat and ran. 4 years pass of Neptune trying to find "that person," but to no avail. Now being 20, she comes back to her small apartment and finds someone waiting outside. He had black hair covering his right eye, and wore a beige coat over a purple vest. Approaching him with caution, he introduces himself as Nikei Yomiuri, and asks Neptune if she'd join him and 3 others to find "that person." (Cover art by me)
