- Kurama: The tree won't stop until its host is dead. As you said, Toguro, your regenerative powers make you unable to die.
- Elder Toguro: I feel so weak!
- Kurama: You will suffer for eternity here, torn between your hate and your agony - and so be it.
- Yusuke Urameshi: Those demons are just lining up for a shot at us - not the kind of crowd you wanna be stuck in a cave with.
- 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.
- Shinobu Sensui: If you can kill Mr. Makihara right now, I'll give Kuwabara back to you unharmed.
- Yusuke Urameshi: What?
- Kazuma Kuwabara: [bound and gagged] Thay yeth! Thay yeth!
- Shinobu Sensui: It's your choice. If you refuse the challenge, I'll deflect any other attack you make by using Kuwabara as a human shield.
- Itsuki: [to himself] Clever tactic, Mr. Sensui. Control their actions by making them believe they have a chance. Instead of trying to predict their next move, you make it FOR them.
- Sadao Makihara a.k.a. Gourmet: Touching, Seaman. You want to save Kuwabara so very badly because he saved you, but at the same time you're terrified of letting Sensui find out how much your new buddy means to you, aren't you?
- Kiyoshi Mitarai a.k.a. Seaman: What?
- Sadao Makihara a.k.a. Gourmet: You're scared Sensui will kill him to punish you for being a traitor. But you've got a juicier one, don't you, Kurama? You're a lot more torn up from killing Gamemaster than Yusuke believes. Not only are you riddled with guilt, you're embarrassed. Yoko Kurama would never be so weak.
- Yusuke Urameshi: It's like he's lifting thoughts straight from our brains. The only one I know who can do that is - Ah! - Murota!
- Sadao Makihara a.k.a. Gourmet: Bingo! That old flimsy? Haven't you wondered where he's been since the hospital let him out?
- Yusuke Urameshi: Eating my teammate - that's on my ass-kick list.
- Kurama: I'll take this one, Yusuke. Don't argue. I am not in the mood.
- Yusuke Urameshi: Mental note: Never tell Kurama he's letting his fox side down.
- Shinobu Sensui: When Toguro told me about the many achievements of the new Spirit Detective, Yusuke Urameshi, I could feel the hands of the universe tugging at my arm. In the trial against humanity, the defense now had an able attorney. At last I could begin the sentencing.
- Elder Toguro: Sensui gathered up a bunch of these new psychics for his plan, including this brainless lump. You see, we both agreed my regeneration was taking too long. I needed another body, so Sensui let this ogre take me, making him think that I was the one being betrayed. Merciless, really. The poor ape had no idea what he'd swallowed. I'm like a cockroach with a brain. The best was when he realized what was happening. That's when he became afraid. Fear is pleasure enough from the outside, but I felt his terror from within as I slowly took him over. It was palpable, a fear so thick I could eat it.
- [Elder Toguro laughs maniacally]
- Kurama: That's enough. You've survived for far too long, and now it ends.
- Elder Toguro: What's wrong with you? Why don't you scream and die?
- Kurama: It's the sinning tree.
- Yusuke Urameshi: The sinning tree? Sounds a bit heavy.
- Kurama: It ensnares your mind with hallucinations of wickedness while it sucks away your life.
- Yusuke Urameshi: Wow, that's freaky. He still thinks he's fighting you even now when he's all wrapped up?
- Kurama: Yes.
