Irina Jelavic

source from wikipedia


 * She is a professional hitwoman of Serbian origin who is hired to kill Koro-sensei by becoming a part-time foreign language teacher in Class 3-E. She uses her charm to seduce Koro-sensei, initially making him obey her commands. However, her first assassination attempt is foiled when Koro-sensei is able to suppress her three hired mercenaries attacks. This ends in her humiliation in front of all the students, and she swears revenge. She teaches the students how to seduce people from other countries, so that with this method, they can learn foreign languages, and usually punishes male students who fail to answer her questions during her lessons by kissing them until they pass out from being overwhelmed. Much to her dismay, she is nicknamed "Professor Bitch" (ビッチ先生, Bicchi-sensei) (formally Ms. Hella-Bitch) by her students. She develops genuine feelings for Karasuma later on, and eventually starts a relationship with him, later becoming his wife and working under him for the Japanese Government as a spy.
