Being thrown into the world of adult entertainment has its ups and downs...

Sona Sitri gets a surprise visit from her sister after a long day of Devil work and checking everything off from her duties from school. What does she want for popping in for a random visit? She got sprung on to have the honor of helping Serafall finding a suitor. For what? A husband. Next to her as Mr. Leviathan who she calls Levinald or Levy for short. I don't own Highschool DxD or the characters but it's a story worth picking up a manga.
