Koenma and Yusuke in “Unfinished Business”

Koenma

Yusuke, you've shown to have more character than I thought. I've been trying to figure out whether people around you really want you back. Contrary to my personal opinion, they actually do. More importantly, you've exhibited astounding potential to be a decent human being. Because this trait is so rare, I've decided to give you another chance. In retrospect, it was a very good thing you threw this egg into the fire. If you had allowed it to hatch, the Spirit Beast, which had been feeding off your constant negative energy, would not have been a pretty sight. It would have bitten your head off. But as you and I know, that's not what happened. You threw the egg into the fire without hesitation, saving Keiko's life at the cost of your own. You have a special quality buried underneath all that crap, and your added experience with death could make you very useful.

[flabbergasted] You think I'm useful?!
