If there was anyone in this world who could drag his sister back from the gates of hell, it would certainly be these two people before him!
He had to beg them! He could only beg them! No matter how humbly he had to beg!
As long as he could make them agree to save Ume, any price— even if they wanted his life— would be fine!
"Wow..."
Seeing Gyutaro's determination to do anything for his sister, Mitsuba's heart was slightly moved.
As if suddenly recalling some distant past, her eyelids lowered and a sigh of admiration escaped her lips.
"Truly enviable. If I had such a wonderful elder brother by my side back then, perhaps I wouldn't have chosen to become a demon..."
"Does Holy Maiden have a poor relationship with your elder brother?"
Hearing this, Doma became curious again.
"We did in the past, but those are all old matters now. Elder Brother has changed a lot these days, it's all in the past..."
Saying this, Mitsuba sighed again.
"Forget it, forget it. Who made me someone who can't bear to see others suffer, a soft-hearted good person... Little one."
She shook her head to herself, finally stepping forward and crouching down before Gyutaro, speaking seriously:
"Your sister's current condition is certain death. Normal methods can no longer save her life.
But I do indeed have two methods here that can still drag her back."
Meeting Gyutaro's puzzled gaze, Mitsuba slowly raised her fingers.
"First, I will give you a flower. As long as your sister wears this flower close to her body, her body will return to its state before the fire. Everything that happened tonight will cease to exist for her.
But you must constantly be careful— once this flower leaves your sister's side, she will immediately return to the state you now hold in your arms, and will likely die instantly.
Second, I will bestow that lord's blood upon you, transforming both you siblings into demons like us, granting you both powerful bodies and eternal lifespans.
But the price is that from now on, you will only be able to live in the darkness of night, and must feed on humans to survive..."
"Second! I choose second!"
Before Mitsuba could finish speaking, Gyutaro impatiently made his choice.
He didn't care about being a demon or not, didn't care about eating people or not.
He only knew that as long as they could become demons, his sister could regain a healthy and powerful body, and could even live forever and ever!
As for humans, demons, feeding on humans— all this messy stuff, Gyutaro didn't care about any of it.
If they couldn't be human, then don't be human. If they became demons, then so be it. If they needed to feed on humans, then they would feed!
Anyway, the two of them had never been treated well since childhood. Even their mother who gave birth to them showed nothing but disgust toward them, viewing them as burdens.
Since this was the case, why should he care about others?
Why should he care about those who had never cared about them?
To hell with it! Let all this messy stuff go to hell! As long as my sister can be happy, that's all that matters!
"Truly resolute..."
Looking down at Gyutaro's eager appearance, a brilliant smile immediately bloomed on Mitsuba's face.
Her palm suddenly split open, and blood slowly seeped out.
"Then, as you wish."
"..."
The transformation of the Gyutaro siblings didn't take too long— just over a day in total.
What surprised Mitsuba was that this pair of siblings actually woke up together.
What surprised Mitsuba even more was that these two siblings had actually become extremely rare "Twin Demons"!
Twin Demons, also known as twin demons— as the name suggests, they were two beings as one, demons with a "shared life" bond.
For this special type of demon, as long as one demon was not decapitated, the other demon would not die even if decapitated.
To thoroughly kill Twin Demons, one had to decapitate both demons simultaneously within an extremely short time frame.
Even in the past several hundred years of history, demons with this special mechanism were extremely rare.
After all, its conditions were extremely stringent— besides requiring the two demons to have close blood relations, they also had to be transformed simultaneously, and both parties had to have a deep bond with each other, and so on...
What delighted Mitsuba even more was that both siblings had each awakened a Blood Demon Art.
Among them, Ume, as the sister, could transform her own flesh and blood into multiple sharp silk ribbons. These ribbons were flexible and sharp, capable of both large-scale slashing attacks and binding enemies.
More importantly, these ribbons could also serve as Ume's "eyes," helping her observe and gather information.
A Blood Demon Art more suitable for gathering intelligence in towns with many buildings, rather than for combat.
As for Gyutaro the brother, his Blood Demon Art was much more offensively powerful.
According to his human combat preferences, after becoming a demon, Gyutaro preferred to use twin sickles forged from his own flesh and blood as weapons.
He could use his own blood, combined with the sickles, for various attacks— such as transforming into blood sickles, condensing blood slashes, and so on...
In terms of application, it was somewhat similar to Doma's Blood Demon Art, much like an inferior mutated version of Doma's Blood Demon Art.
If developed diligently, perhaps more attack methods could be researched in the future?
Additionally, Gyutaro's blood also carried potent poison. Even a slight scratch could allow the toxin to rapidly invade the human body and take effect, quite lethal.
"Above is the complete current ability summary of this sibling pair, Lord Muzan."
Late at night, inside a private room of a courtesan house in the entertainment district, Doma and the Gyutaro siblings were heartily sharing several Demon Slayers that Doma had just captured from outside.
Meanwhile, Mitsuba sat alone to one side, reporting to Muzan who was far away in another location through mental communication.
[So what do you think of them, Mitsuba?]
"I believe Lower Rank would be completely no problem for them. With effort, perhaps becoming Upper Rank is also possible.
After all, the situation of Twin Demons both possessing Blood Demon Arts is indeed rare— this has only happened once in several hundred years.
And setting Ume aside for now, Gyutaro indeed has considerable potential. If trained well, he can certainly become a good helper for Lord Muzan in the future..."
Mitsuba replied seriously.
As the excellent secretary of the Demon King, temporarily holding the power to convene Upper and Lower Rank meetings, and possessing the authority to decide the seats of the Twelve Kizuki as Upper Rank One.
Although she really didn't want to do this in her heart, she would still work seriously when it was time to work.
Sigh, no helping it. Who made their Demon King lord withdraw into his shell and stop caring about anything...
