Oukyuu ni wa "Are" ga Iru

I object to that false accusation!! This great revenge story starts with a foolish denouncment... At his graduation party, the second prince suddenly denounces Irmhild for the crime of threatening her half-sister. He claimed Irmhild had committed crimes such as pushing her half-sister down the stairs, but the only proof he had was a witness claiming the criminal was a girl with blue hair. "Are you sure you want to do this? I, Irmhild Rippencrock, haven't even been at school this year..." She must clear her name of these crimes, so... Are you ready, Your Highness?
