Shinobu Sensui:
C-class apparitions are like seeds, abundant and worthless, but one of every hundred grows into a B-class with brains and strength that can easily surpass a human's. Want to tell us first-hand, Hiei and Kurama? And then from the B-class a handful take the next big leap, intellect close to omnipotence, bodies of huge size and power, creatures fit for human legend, like the Titans of Greek myth.

Yusuke Urameshi:
I getting really tired of hearing you talk.

Shinobu Sensui:
They are the A-class demons. They're probably watching us right now from the pits of Demon World, waiting for their chance to rise to glory.

Yusuke Urameshi:
Share me the pep rally. You're gonna kill people you were supposed to protect.

Shinobu Sensui:
My job was to protect the universe as a whole, and that's exactly what I'm doing.
