Counting all the students and teachers in 'Assassination Classroom' feels like revisiting an old yearbook—so many faces with distinct quirks! Officially, Class 3-E has 28 students, plus their inhuman teacher Koro-sensei. But if we include recurring figures like Principal Asano, Irina Jelavić (aka Bitch-sensei), and Tadaomi Karasuma, the roster expands to around 40+ named characters. What's wild is how each student gets their moment, from Nagisa’s quiet cunning to Karma’s chaotic brilliance. Even side characters like the original assassination targets or the government officials add depth. The series really makes you remember them all by giving everyone growth arcs or standout gags—like Sugaya’s art obsession or Hara’s terrifyingly perfect smile.
Honestly, I sometimes rewatch just to catch tiny interactions I missed, like Nakamura’s sarcastic asides or Maehara’s failed flirtations. It’s rare for an ensemble cast to feel this balanced, where even background characters like Kataoka or Yoshida have defining traits. And let’s not forget Koro-sensei’s 100+ tentacle forms—technically one character, but each expression is a mood!
