To Love Ru Darkness, Vol. 3

Momo wants to hook up high schooler Yuuki Rito with the girl of his dreams-but why stop there? She won't be happy unless he gets all the girls of his dreams. To make her "harem plan" a reality, Momo sets Rito up on a date with Run. There's just one small hitch: Run is a shapeshifting alien, who can turn into a boy at a moment's notice.
