Meru is a 19-year-old who lives with a sense of emptiness. She started an erotic account (urameru666) out of curiosity, and her followers steadily increased. She was happy to be praised for being "erotic." However, she felt something was missing, and unfulfilled. To escape from this world of emptiness, she thought, "If I like sex, why not appear in an adult video?" and she appeared in an adult video. The girl who was usually erotic was indeed erotic.
