Final Lesson (Koro-Sensei)

Yo... this ain't just a class, it's a goddamn battlefield

Taught 'em to kill me—shit, I taught 'em to feel

Started out with a smirk and a yellow grin

Fast as fuck, eight tentacles, born to win

They called me a monster, a threat to the Earth

But I gave that classroom a reason for worth

Assassins in training, sharpenin’ blades

Made 'em deadly as hell while the rest just prayed

I saw pain in Karma, fury in his flame

Saw Na-gi-sah silent, but cold in the aim

Each of 'em broken, fuck society’s rules

I turned rejects and loners to sharpened tools

They aimed for my head but I gave 'em my soul

I was born to destroy—taught 'em how to be whole

Government watchin', shit, they hated my glow

"Why teach 'em love when you know you gon’ blow?"

But I gave 'em freedom, the truth they deserved

'Cause every damn lesson was more than just words

I ain’t no savior, I’m the goddamn storm

Rippin’ through fate with this mutated form

Fuck a lab coat, I’m rockin' this tie

Teaching death, math, and how not to die

Karma's rage, Na-gi-sah's calm

They became the balance, the open palm

Told 'em "If you kill me, don't look back"

"Take what I gave you and never crack"

This my final lesson, blood on the board

They can take my life, but they can't kill the sword

I made of each of 'em—deadlier than me

Now let the classroom set the monster free

I ain't cryin', just got some blood in my eye

Memories flashin' like that final goodbye

Na-gi-sah, cold blade, heart of frost

He’s the one who'll lead ‘em when the world's lost

Told 'em truth 'bout that past and regret

I was a weapon, but I never forget

How it felt to be human, to laugh, to teach

Even monsters like me got souls to reach

Fuck your orders, I ain't your puppet

I broke the mold, said fuck it and cut it

Class 3-E, my pride, my sin

Kill me now—but let the story begin

So slit my throat if you got that drive

But remember, because of me—you’re alive

They made me a target, gave me that doom

But I built a family inside that classroom
