Unohana Retsu, being a millennium-old Shinigami, could understand Rias's thoughts.
Even so, she couldn't help but be amazed by Rias's magnanimity.
Thinking carefully, both Rias and Jibril were good children.
Although Jibril's initial performance had made her very wary, Rias was completely different.
If it was her, perhaps she could be trusted!
"If you have time, you can come visit my world."
Unohana Retsu said suddenly.
"Hmm?"
Rias looked at Unohana Retsu in surprise, then nodded and said, "Maybe in a few days; my world has some problems that need solving recently."
The reason Unohana Retsu made such a decision was not only because she was moved by Rias's actions, but also because she acknowledged Rias's character.
Since that was the case, Unohana Retsu would no longer be wary of what bad things Rias might do if she went to her world.
"If you're free, you can also come to my side~"
Jibril smiled sweetly. "Master, Lord Artosh is very interested in you, and of course, my sisters are as well."
"Yes, as the local host, I will also protect you and won't let you be harmed."
This time, her words carried no killing intent.
It wasn't a facade; Jibril truly thought so from the bottom of her heart.
Unknowingly, Jibril had been changed by Rias.
"Using 'you' as a formal honorific sounds a bit awkward coming from you."
Rias couldn't help but say.
"How could it be?"
Jibril said, "You possess the qualities that earn my respect; this is admiration from the bottom of my heart."
"Well, suit yourself."
Rias didn't really mind.
"Speaking of which, Miss Jibril, don't you want to come to my world anymore?"
Unohana Retsu chuckled.
"I'm busy; I have no interest in a bunch of ants."
Jibril glanced at Unohana Retsu, her tone showing no fluctuation.
For Jibril, if she liked something, she liked it; if she hated it, she hated it; if she was interested, she was interested; and if she wasn't interested, she truly wasn't.
Perhaps there was a tiny bit of interest, but clearly, its proportion in her heart had dropped.
"That really is a pity."
Unohana Retsu smiled very brightly.
Unknowingly, she herself had been influenced.
All of this was brought about by Rias, the Little Cutie who called herself a devil.
For the first time in a thousand years, her heart felt so at peace.
She's truly an incredible person... such a change seems quite nice as well, Unohana Retsu thought.
Soon, three days had passed, and Rias couldn't help but yawn.
Although the research had progressed, there were no fundamental breakthroughs.
However, for Jibril, it could be considered a breakthrough.
Although no breakthrough progress was made in the three areas of Magic Formula and Sacred Gear concepts, and the Fusion Equation.
Using this power briefly was no longer a problem.
After teaching the construction Formula of the Zanpakutō to Jibril and returning to reality, Jibril was the first to manifest the Zanpakutō into reality.
Although there was still room for improvement, it didn't mean the current Zanpakutō was useless.
A Zanpakutō, combined with the first stage of the Fusion Equation.
The Shikai would cut into the opponent's body with its sharp edge, and then the Bankai would gather power into the blade to explode inside the opponent.
Simultaneously with the explosion, the first stage of the Fusion Equation would be activated—energy fusion!
This would result in an explosion of power beyond imagination.
According to calculations, this power might already be capable of dragon slaying!!
At this moment, another matter was bothering her.
How could she give back to Rias?
Although Rias said it was enough to just keep it in her heart, she was not a shameless person.
To take blindly without giving back—instinctively, she was unwilling to do that.
"Right, knowledge."
Jibril thought back to what Rias had said before.
What she owed was not just the concept of this technique, but also the previous debt: information on the existence form of the Dragon-kin.
That information involved capturing some Balen from the Forest Spirit Race and giving them to Rias; because she hadn't cared before, she almost forgot.
"All the knowledge of the Forest Spirit Race."
Jibril murmured, "But I still feel it's not enough."
"Right, Little Rias likes techniques; perhaps she would like the bones of Dragon-kin, or maybe Giant Species and Fantasy Species..."
"But Little Rias is very busy now; I'll wait for a while before mentioning it."
Jibril thought.
Regarding Fantasy Species and Giant Species, she had the record of subjugating them single-handedly.
Now she only lacked the achievement of soloing Dragon-kin and God Species.
No, last time the Flugel collectively tried to subjugate a God Species and failed; clearly, she was still far off.
Dead Fantasy Species were fine, but to capture one alive, she was still lacking too much.
In comparison, Rias preferred them alive.
Moreover, trophies like heads only had symbolic meaning for the Flugel who subjugated them; for Rias, the value would be much lower.
"It's decided. After I get stronger again, I'll catch a Fantasy Species to give to Little Rias."
"She'll definitely be very happy."
Thinking of this, Jibril couldn't help but smile.
She didn't realize at all that her smile was very similar to Azrael's, with a bit of a silly, dorky feeling.
——————
On the other side, her consciousness returned to the main world. Rias yawned and rested for a short while.
Despite being a devil, she was ultimately still a living being; she couldn't manage to go completely without sleep yet.
After a short nap, Rias woke up to find that it was already the next day.
"Am I tired?"
Rias muttered to herself.
Recently, she had found a way to increase her magic capacity and consume it rapidly.
While creating familiar butterflies, she used this method to train her magic capacity.
Although the results weren't great, it was faster than before.
Nevertheless, it consumed quite a bit of energy.
Especially since she often studied techniques in the Arena, which was very mentally taxing.
The sound of 'tap-tap' knocking appeared, and then Rias heard a maid's voice: "Eldest Young Lady Rias, the young lady from the Sitri Family requests an audience."
"I understand."
Responding, Rias rubbed her eyes and then stood up.
Because she was used to sleeping naked and didn't like being disturbed.
She had created a barrier in the room, automatically maintained by Rias's Formula.
Crawling out from the quilt, the Formula positioned in the center of the room activated, releasing a tiny breeze.
The breeze blew over, bringing a hint of coolness.
She spread her arms and closed her eyes, enjoying the feeling of being brushed by the wind~
Rias really liked this feeling of being free from restraint, but she would only do this when she was alone.
There was a barrier outside, and her body was surrounded by a layer of Power of Destruction; if someone looked over, they would only see a crimson ball of light.
That was Power of Destruction.
Destruction Formula Six: Absolute Destruction Barrier.
This was the absolute barrier she maintained daily; it would only destroy things that would harm Rias or things that Rias wanted to destroy.
Things she didn't want to destroy would not be harmed. This was the biggest difference between Rias and Sirzechs: absolute control over Power of Destruction.
A minute later, with a flash of red light, Rias put on her clothes.
"Today's condition is also good!"
Moving her limbs slightly, Rias felt full of energy.
"Time to go play with little Sona-chan~"
