After calming down Serafall, Kisuke showed her where Akeno and Irina were resting, "T-this is?"

Serafall saw them floating in a blue liquid within a glass tank, naked, "What happened?"

While checking their vitals and changes on their bodies on the terminal, Kisuke answered, "They were contaminated by a very strong Dragon Slayer curse. Thanks to that, their original bodies had to be discarded."

"...Samael's curse, I see... T-then what are these?"

"So It's called Samael's curse. Well, I grew them in accordance with their DNAs, and some other things like preserving their Devil and Angel factors since their Evil Piece and that card were removed."

Serafall took a deep breath and held her head due to the slight headache, "You preserved their Devil and Angel parts without the Evil Piece and the Brave Saint Card?"

Adjusting the density of the medicinal solution, Kisuke answered blankly, "Well, yeah. It's a bit tough but I'm glad I was able to do it without messing up big time."

'A bit tough?' Serafall's headache worsened, "What other things did you do aside from preserving those?"

"Ah, that was the hardest part. You see, when I found Ophis-chan, Himejima-san, and Irina, they were on Great Red's back and Ophis-chan was trying her best to keep them alive."

"M-mhmm..." Serafall decided not to say anything else for now and listen.

"And while I was about to reconstruct their bodies, Great Red offered his help and parted with a bit of his flesh and scale. Not wanting to lose, Ophis-chan also gave part of her power."

"Are you trying to say that a part of these new bodies are Great Red's flesh and Ophis-chan's powers?" Serafall finally reached the limit of her understanding.

"Yeah, but the hardest part is actually balancing it with Samael's curse."

"...S-Samael's curse...? What do you mean?"

"Iya~, I thought it would be such a waste if I didn't use it! Since I got the chance, I went all out! And thankfully, I managed to do it and I learned a lot of things in the process~!"

At that point, Serafall snapped and shouted, "WHAT THE HELL!?"

Kisuke was startled at her sudden outburst and looked at her with eyes wide open, "What's up?"

However, Kisuke's clueless face infuriated Serafall more, "Don't you realize the problem!?"

"...For what?"

"Grahhh!!!" Serafall uncharacteristically scratched her head before she pointed towards Kisuke and started explaining, "First of all, Samael is an existence that was erased from the records and his most redeeming feature is his Dragon Slayer properties which is of the highest level that it could even affect Ophis and Great Red, the strongest beings in this world!"

"Yeah, I figured that out when the curse wasn't drowned by both Great Red and Ophis' powers. That's what made it possible to combine it with their powers in the first place."

"T-then how did you combine two opposing forces?"

"Opposing? No, you got that wrong. 'Dragon' and 'Dragon Slayer' were never opposing forces. The only difference they have is the 'goal'."

"Goal?"

"Yes. The 'Dragon' is an oppressive form of power against all other things. Meanwhile, the 'Dragon Slayer' uses the same base as 'Dragon', but instead of all other things, it's against fellow 'Dragon', directly targeting their weakness."

"It's hard to explain it in words, but you can imagine a 'Dragon' is a pressure-resistant material that could easily hold everything while 'Dragon Slayer' is the needle that could easily puncture it. Both could be made from the same materials but could be designed to be used differently."

Serafall massaged the bridge of her nose, "Yeah... I can understand your analogy..." But deep inside, Serafall knew that it wasn't that simple, 'I guess that's how Issei-kun managed to keep Ascalon within the Boosted Gear, however, the difference between the Ascalon's power and the Heavenly Dragon Emperor is so large, and it was only possible because it could contain it. Samael's curse is different...'

However, Serafall didn't voice out any of her concerns regarding this, as she knew she wouldn't be able to understand it either way. Besides, there are still some other problems that she's more concerned with than bodies that Kisuke is cultivating, "The Dragon genes are indeed more than surprising, but that's about it, so let's set that aside for now."

Sighing, Serafall continued, "The main problem is the fact that you preserved their Devil and Angel side without the help of the Evil Pieces and Brave Saint Cards."

Kisuke stopped for a moment and thought about Serafall's words, "So you're saying that the fact that I made them Devil and Angel without the help of those systems is the problem? If so, then I can understand your concerns. If this were to go out, it'd become complicated out there."

"Right. The conversion isn't as simple as just changing the body. The Evil Pieces and Brave Saint Cards system isn't just there to change the physiology but there to let the 'Master' lend their energy to their non-Devil or non-Angel servants to slowly convert their own energies."

Serafall sat back down before continuing, "If you were to suddenly change everything, including their energies, loads of problems will come out, and the biggest one of them is the problem of the soul not being able to adapt to the sudden change."

"This is also the reason why stray Devils are very problematic. Without their 'Master', only a few things could happen. First is the safety feature of the Evil Piece kicking in. This will stop the conversion and will slowly revert them to their normal race."

"Second is when that safety feature failed to activate. This is very common to those Mid-Class and High-Class reincarnated Devils, they are already so strong that they can't be reverted back. As a result, without the supply from their 'Master', the body will wildly convert almost everything to Demonic Power, and a not fully mature reincarnated Devil wouldn't be able to take this conversion. In most cases, they'd look for more energies around them and most of the time it's through 'eating' others. It was also at this point that their soul is already affected and corrupted. Instead of a full-grown Devil, they'll just turn to violent and hungry monsters."

"The third case is when the reincarnated Devil is strong enough even though he or she is not a mature Devil. Thanks to their strength, they will be able to take the sudden conversion. This is the case with Kuroka after she became a stray Devil. However, someone of her caliber is very scarce that this is not a very viable method of converting many Devils at once."

Serafall then looked towards Kisuke, straight to his eyes, "As I recalled it, Akeno is just a Mid to High-Class level while Irina is also around the same level, albeit a little bit weaker. Without the Evil Piece and Brave Saint Card, they'll only suffer... Or did you find a way for that not to happen?"

Serafall already instinctively knew of his answer but still chose to ask. Depending on his answer, this is really a very problematic case.

"Yep, I'm aware of those problems and most of it stemmed from the soul not being able to adapt to the body."

"...Then..."

Kisuke nodded at her, "Since I'm aware of those problems, I also knew how to solve them. I can confidently say that Himejima-san can remain a Devil and Irina can remain an Angel without the problems that you spoke of."
