Dragon Ball Z, Season 9

Elder Kai:
I'll give you the life that's left inside of me. Then you can make your return to Earth.

Goku:
You mean, you're giving up your life...for me?

Kibito:
Venerable Elder, this is the most unorthodox behavior! You can't just offer up your life to handle a single...situation!

Elder Kai:
As usual, you're missing the bigger picture. After Earth, Majin Buu will come here.

Kibito:
Huh!?

Supreme Kai:
If that is true, then let me give up my life.

Kibito:
What!? No, master!

Supreme Kai:
Majin Buu has been my enemy to destroy since Bibidi thousands of years ago and repeatedly, I've failed. You must allow me to pay my own debt.

Elder Kai:
You're ambitious, but too hard on yourself. Let the old men sacrifice their lives so that the young ones can live.

Supreme Kai:
My dear Kai...

Goku:
You're...too kind.
