Shuriken Sentai Ninninj2015

Sasuke:
Before we start the ninja training, I want you to consider what a ninja is.

Takaharu Igasaki:
We know that! Those who are ninja do not give in to fear worries. Or take things lightly.

Tsumuji Igasaki:
Good.

Takaharu Igasaki:
Right?

Yousuke Shiina:
That's important, but not quite.

Tsumuji Igasaki:
Not quite!

Takaharu Igasaki:
Eh?

Sasuke:
Hidden from people, we cut down evil. That's what a ninja is.

Yousuke Shiina:
Unbeknownst to people, unbeknownst to the world. We become shadows to strike down evil. That's what a ninja is.

Takaharu Igasaki:
Eeh?

Sasuke:
You're shinobi but you don't hide? If you keep saying that, you'll never be a real ninja.
