- Genkai: It's too much. Your body can not take any more. I'm removing the Spirit Wave Orb before you're just a lump on the floor. Come on. Ah...
- Yusuke Urameshi: Hey! D'hey, give that back, you old bitch!
- Genkai: Don't be an idiot, Yusuke. Making you absorb this energy so early was a gamble, and now we see why. All my training with you will be a waste of time if you're not even alive to fight against Toguro. Perhaps there's still time to put it off.
- Yusuke Urameshi: Shove it up your ass! You're not my freakin' mother, so don't try telling me what's good for me!
- Onji: Even with YOUR abilities, the Dragon of Darkness Flame can roast you like a blond chicken on a spit.
- Koto: Kuro Momotaro's body is now covered in hair. So much for those freshly waxed washboard abs I loved so dearly.
- Kuro Momotaro: My body does this neat trick where it remembers the pain of my opponent's attack. All I have to do to get immunity is expose myself to a small dose of my enemy's offense, kind of like a flu shot.
- Koenma: This is no time for misty watercolor nostalgia. Hiei is in serious danger.
- Hiei: Who am I to turn down a fan's request.
- Kurama: The flame took its toll on Hiei.
- Kazuma Kuwabara: What?
- Kurama: To summon the dragon, Hiei must use his own spirit energy as bait to lure it from the pits of Spirit World. His technique only works if he can emit a tremendous amount of energy for a prolonged period.
- Onji: [chuckling] Yes, you are correct.
- Kurama: Hiei was in peek condition when he used the Darkness Flame against Zeru, and even that wasn't enough power for him to control it. The beast nearly took the hook along with the bait.
- Hiei: Death will come long before surrender.
