Akuma de Sourou
  Akuma de Sourou is by Takanashi Mitsuba.

  Kayano is a painfully shy 2nd year high schooler.  When she finally  gets the guts to give a love letter to the guy she likes, everything goes wrong!  She accidentally gives her letter to the school's bad boy, Takeru!!  In the process of running away, she drops the letter, which Takeru picks up.  When Kayano goes back to look for the letter, Takeru tells her he has it.  Takeru commands Kayano to be his servant if she wants him to keep the letter a secret (dirty pig )!!!  What will Kayano do!?!
