Offered as a sacrifice to the Demon King, Nike becomes pregnant, and gives birth to the adorable mixed-blood 'Nichrome.' "I want to find your father for you." Though he is a child with demon blood flowing through him, for the sake of her beloved Nichrome's future, she tries to find the child's father. The only clue is the pattern on his chest.
