Serafall furrowed her brows and asked Kisuke a serious question, "Why do you always design things that intentionally hurt the user?"

"Uhmm... No pain no gain? Anyway, hear me out first. Depending on how you use it, the chances of you dying is close to zero. I also won't force you two to take it and allow you to decide after hearing out the benefits and risks."

Issei then answered, "We're listening."

"Great," Kisuke nodded and proceeded to explain further, "The main goal and use of this modified blood is to change or evolve your physiology closer to that of a Dragon, which would allow your bodies to directly convert your reserves to Dragon Aura, or even store it for future use."

Issei and Vali's curiosity and interest peaked after hearing that.

"Now, to actually do this, after taking this blood, using your Sacred Gears as the catalyst, you'll have to convert either your Ki or Demonic Power to that of a Dragon's Aura and resist it before it melts your flesh."

Not just Issei and Vali but the majority of the rest swallowed a mouthful of saliva due to Kisuke's graphic description.

But Kisuke didn't mind their reactions and kept going, "Of course, you can directly use your Demonic Power or Ki to resist it, but that would only defeat the purpose. You see, Dragon and Dragon Slayer, despite being complete opposites, have the same origin, similar to the both of you."

"As you resist the blood, your body will slowly adjust to the damage it has taken. Thanks to the blood and your Dragon Aura, your bodies will be forced in a certain direction, but you can think of this as mastering a specific path that is very suitable for you."

"If you take this slowly, you should be able to use Dragon Aura directly and doing it enough will improve the entire base of your abilities."

Vali immediately caught on to Kisuke's words and asked, "If we take it slowly... What would happen if I took it all at once?"

Kisuke grinned and replied, "Simple~ The chances of you dying shoots up exponentially~ As you are now, the chances of you dying if you took it all at the same time would be around 95%~"

"As I am now, huh... So I can prepare myself to mitigate those chances?"

"Absolutely right~!"

"Then what do I get by risking my life like that? As you've said, no pain, no gain, right?"

Kisuke looked straight into his eyes and answered, "According to my calculations, the amount you take in a short period of time increases the speed and quality of the transformation. So I can say that the more you take, the better the result would be. And if you're lucky enough, you might even develop enough to get the same level of resistance to Dragon Slayer properties as Great Red and Ophis themselves."

Vali then started chuckling, "Then I'll take it. Though it'll take some time to prepare."

"Vali... Are you sure?" asked Azazel with a concerned expression.

"Not now, but I'll definitely take it in one go," answered Vali with a small smile.

"Same with me. I'll take it in one go," Issei suddenly added.

"Issei!? No! You don't have to do that!" Rias immediately rejected Issei's decision in fear that something bad may happen to him. Asia, on the other hand, grabbed the sleeve of his shirt and agreed with Rias.

But instead of replying to them, Issei faced Kisuke, "Kisuke, what're my chances of surviving if I take it now?"

"Hmm... In your case, it'll be around a 75% chance of death."

Vali's eyes widened at his answer but Kisuke immediately explained, "The training he's doing is already taking him in that direction so he's not in as much danger as you are."

"But even then!" Rias still tried to convince Issei against it.

"Buchou... No. Rias," Issei held her hand, "Although my chances are better, it doesn't mean that I'll take it now. I'll take it after ample preparation. And if there is any truth in any of Kisuke's speculations, then all the more reason to maximize its effects." He then faced Asia and patted her head, "You too, Asia. You don't have to worry too much. I won't do it until I'm sure I can safely do it. Besides, Azazel won't allow us to continue if he's not sure that we're not safe."

Asia and Rias looked towards Azazel and the Governor of Fallen Angels scratched his head and sighed in frustration, "Dammit... To have this kind of option, you're more Devilish than most Devils out there."

"I just don't want you people to be cornered without any other options left," answered Kisuke.

Azazel stayed silent for a moment before sighing again, "Fine... But the two of you can't take it without me around. I'll try to get the help of the Five Great Dragon Kings to assist your preparations. That way, you'll have more chances."

Sun Wukong tapped the table and said, "You don't have to worry about Yu Long. I'll ask him myself and I think he won't refuse to help."

Azazel nodded his head towards Sun Wukong and gave his gratitude.

Asia raised her hand and added, "I'll also ask Fafnir-san for his help!" Since she entered a contract with the Gigantis Dragon, Fafnir, Asia is the one in control of him.

"Then I'll try asking for Tiamat's help," added Ajuka.

"Since we're getting their help, I'll ask Midgardsormr myself," said Vali.

"As for Vritra, we'll ask Saji Genshiro to convince him," replied Sirzechs.

Azazel smiled and said, "Thanks, everyone. If every one of them could help, then we should be able to significantly reduce the risk for these two idiots."

Seeing that they already came to a decision Kisuke stood up, "Well then, I've already said everything I wanted to say, so I'll be leaving first," He then looked towards the two hosts of the Heavenly Dragons, "I won't be saying anything else beyond this because I don't want your perceptions to be warped any further. Even though I pushed you onto a certain path, it doesn't mean that the possibilities were reduced. It's still up to you two on how you'll improve and evolve further. Just one last thing, you are what you think you are. Remember that and you'll be fine."

But as Kisuke prepared his teleportation magic, Michael stopped him, "Please wait, Kisuke Urahara."

"Hmm? What is it, Michael-sama?"

"From what I heard, you'll be leaving for a long period of time again?"

Kisuke nodded, "Yes. I'll probably leave in a day or two."

"Then before you leave, if it's not much, could you meet with us again?"

"What for?"

Michael smiled wryly while Azazel and Barakiel sighed in resignation, "Well, we're not sure yet, but we'd like to talk about something with you."

Kisuke tried to guess what they wanted to talk about but he didn't have much clues. Although he still agreed as it's not much effort, "Alright. But I won't have much time by then so please keep that in mind."

"Don't worry. It won't take long."
