Yu Yu Hakusho Season 4 Episode 18

Kuwabara: (mockingly) What's up, Mister Mazaku? I thought you were goin' to Demon World to become the king?
Yusuke: I will, someday, but who's gonna be here to kick your ass?
Kuwabara: Well, if you're goin' back, I better give you the beat-down now I was always too nice to do!

Keiko: Yusuke... this is the end! I'm tired of waiting for you, Yusuke! Half my life, I've waited for you to come around! Even when you were here, you weren't, really; you weren't here for me! Go on fighting, but it's time I get what I want!
Botan: I could cry...
Yusuke: I don't want you to wait, either.

Kuwabara: I met Genkai for the first time ever after going up these stairs, and I ended up fighting against Rando. Though I didn't know it at the time, it was the first case Urameshi and I worked on together. After that, it was Maze Castle-- I met you and called Hiei a rut-boy for the first time. And then, Tarukane and my pinky string and meeting the love of my life. And then it was the whole Dark Tournament with Toguro, and then Sensui, and now this. This journey sounds great, but it means that's all over; you gotta move on... it's just hard to believe.
Kurama: True, but when we need to, as you just have, we can remember.

Genkai: Once you've given me a teary-eyed funeral, I'll be leaving this whole estate to your group. That includes this temple and all surrounding land. A shore on one side and a stone wall on the other will tell you where it ends. Leave nature as it is. It takes several hours by car to reach the closest town-- not a convenient place for humans to live, but perfect for apparitions. The Kekkai barrier is down, but it will take a long time for humans and demons to live in peace. I spent my life trying to understand a demon and failed. Make this a safe house to bridge the gap as I never could.

Genkai: There's only one reason I've asked you all to come. These recent years have caused me to think about my legacy and so I want to tell you what to do after I die.

Kuwabara: Koenma?! Where'd you come from?
Koenma: Well, that's a lengthy story-- you'll just have to ask my dad.
Kuwabara: You cheeseball!

Hiei: Don't worry, old fool, you're not dead. We'll get you back home quickly enough. But first I have to do a little procedure to make sure you don't remember any of these fun things when you wake up. Pleasant dreams. (Snaps his fingers to put the human to sleep)

Mukuro: You can go back to the human world. I'd make sure no one came looking for you.

Hiei: (Props his feet up on the table) Hm. That's not why I stay.
