Haiiii~! My name is Mika or Miraki,prefer what you want. So this is an AssClass X Reader. NO LEMONS. (/☆^☆\) So just request some of your baes in the comments. By the way you can add like Karma x Neko!Reader for example. Got a little inspiration from Ichigossu and Nadthenuttela from their awesome books. K Sayonara (☆*<)/
