"This is Kayko. I'm worried about Yusuke. He has been gone for so long now. Off fighting, I know he enjoys it, but things are being neglected in his absence. So many enemies but there are friends to help along the way. Both the worst and most magnificent is yet to come. But will one solution only lead to another problem? Oh Yusuke! Please take care. Please be all right. And please don't do anything stupid! I want you to come back to me, next time on YuYu Hakusho Beyond!"
