Known throughout Class 3-E as 'Bitch-sensei,' Irina Jelavic is a globally renowned assassin who weaponizes her stunning looks and fluency in ten languages to eliminate targets. Dispatched by the Ministry of Defense under the guise of an English teacher, her true mission is to take down Koro-sensei. Though her arrogance initially created friction with the students, her time in Class E gradually softened her edges, revealing a genuinely dedicated educator and a fierce protector. Beneath her glamorous façade lies a past scarred by war-torn loneliness—and a surprisingly innocent, fumbling heart when it comes to matters of love.
