Irina Jelavić (Japanese: イリーナ・イェラビッチ Irīna Yerabicchi), primarily known by the students of Class 3-E as Professor Bitch (to her dismay), is a professional hitwoman trained by Lovro and the language arts teacher of Class 3-E, employed by Kunugigaoka Junior High School. She is a secondary protagonist in the manga and anime series Assassination Classroom. She is portrayed by Martha Harms in the English dub of the anime, and Shizuka Itō in the original Japanese version.

Physical AppearanceEdit

Irina stands at 5'7" (170cm) tall, and has long blonde hair, blue eyes and fair skin. Described as beautiful, she has a seductive body, with large breasts and hips to accentuate this; though she primarily uses her appearance to seduce males she intends to kill. She often wears expensive, high brand clothing, to give the appearance that she is of celebrity status.


Irina works as an undercover hitwoman, often seducing her male targets before going in for the kill. She is considered a great actress, and uses these skills to adapt to any situation thrust upon her. She is ruthless when it comes to killing, and would never give up on a job until her target is dead. Outside of work, Irina is incredibly clumsy; and the luxury lifestyle she lives as a hitwoman causes her to be somewhat childish in normal situations; often to the chagrin of Tadaomi Karasuma.

However, Irina has deep insecurities about herself and she trusts very few people because of this. Due to traumas in her childhood, Irina shuts out all her feelings, and seems to be afraid of them at times.
