3. "I study too, you know...How could I teach anyone if I didn't grow and learn day by day?

Now let's get rid of this dangerous cloth. Experiencing my Absolute Defense Form over summer vacation taught me yet another skill: compressing not my whole body, but a portion of my tentacles to release a burst of energy. Remember this Itona, I say assassination is education...The assassination classroom teacher will get stronger every time he teaches!"

-Koro-sensei,  'Assassination Classroom.'

4. "Fun times are bound to end."

-Koro-sensei,  'Assassination Classroom.'

5. "As you go through life, the might current of society is bound to get in your way and there will certainly be times that things don't go as you'd hoped.

When this happens, don't look to society for a cause...Do not renounce society. Frankly, you'd be wasting your time...Instead just say, 'That's life!' and muddle your way through with frustration."

-Koro-sensei,  'Assassination Classroom.'

6. "To win, one has to lose!"

-Koro-sensei, 'Assassination Classroom.'

8. "All of the connections we encounter in this world serve as teachers who nurture us."

-Koro-sensei, 'Assassination Classroom.'

9. "Those who can't do what they have to when the time comes for action will find their presence fading in our classroom. An assassin who neglects to sharpen his blade is no assassin at all. He's just a boastful brat swinging around a rusty sword."

-Koro-sensei, 'Assassination Classroom.'

10. "It’s dangerous for them to grow up without experiencing true competition. Because they’ll keep whining, even without taking the matter seriously. For those with a high level of aptitude... The sooner they know the frustration of defeat, the greater their growth will be."
