Rias is the princess of the Gremory Household, and her older brother Sirzechs is a total siscon.
Not only would it be in the inventory, but even if it weren't, Sirzechs would find it for her.
After sending the Sacred Gear to Jibril, Rias returned to the library once more.
"Right, @Unohana Retsu."
She almost forgot there was another person in the Chat Group.
Unohana Retsu: "Is something the matter, Devil... Miss?"
"Call me whatever you like."
Rias: "Zankensoki and asauchi—do you want to trade?"
"You even know about things on my side..."
Unohana Retsu smiled and said, "What do you want to trade with?"
"Equivalent knowledge."
Rias said, "Also, I can be your sparring partner."
Unohana Retsu: "Sparring partner?"
"The Chat Group has an Arena function. Since you don't enter with your true body, death isn't an issue. Also, once inside the Arena, time in the outside world is essentially frozen, which is very convenient."
Although there hadn't been a real battle, according to calculations, Unohana Retsu was on par with a High-Class Devil, and her strength was already quite formidable.
And although Rias was only three years old, her Destruction Magic Power had already awakened; at age three, she already possessed the strength of a High-Class Devil.
Combined with her unique fighting style and original techniques, she wouldn't fare too poorly even against a Devil King.
And the so-called Devil Kings weren't the Old Devil Faction royalty or those small-fry from the Chaos Brigade, but Devil Kings like Serafall.
Of another note, reaching the level of Transcendents would still take some effort.
"In other words, Miss Devil is very strong?"
Unohana Retsu narrowed her eyes slightly.
"I wouldn't call myself strong. After all, I'm part of the new generation of the Devil race and still quite immature in many aspects. In this world, my strength doesn't even rank."
Rias said, "But I understand Miss Unohana's strength. Your technique and battle experience are superior to mine, but you lack raw power. Our strengths are roughly equal, so as sparring partners, we can better improve together."
In the world of Shinigamis, Unohana Retsu's strength was already among the very top tier.
Even the Royal Special Task Force, the members of Squad Zero, would not be significantly stronger than her.
The only person capable of suppressing her in all aspects was the Captain of First Division, Yamamoto Genryūsai Shigekuni.
And yet, such strength was considered 'unranked' according to that Miss Devil?
Undoubtedly, this stirred the flames of battle she had suppressed for a thousand years.
"I'll have to face it eventually."
Whether she was making an excuse for herself or truly thought so was unclear.
Unohana Retsu glanced at the Arena rules in the group, thought for a moment, and revealed a smile like a demon's.
As expected, she was finding an excuse for battle.
She had lived in peace for over a thousand years, but that didn't mean she had completely let go.
Years of cultivating her heart had only suppressed the killing intent within; in essence, she could revert back to that unprecedented great villain at any time.
"Very well~"
Unohana Retsu smiled and posted: "But first, a sparring session. I want to see with my own eyes before I can judge whether I can trust Miss Rias."
Without a doubt, this was an excuse.
However, this was exactly what Rias had in mind.
After all, her power was extremely dangerous. Even if she could control it perfectly, she couldn't be certain she wouldn't hurt others.
To truly improve, one must face life-and-death struggle and put oneself under pressure.
"Fine."
Rias replied.
With a thought, she clicked on the Arena and sent an invitation to Unohana Retsu.
In the next instant, Rias appeared within the Arena.
At the same time, Jibril's figure appeared in the spectator stands nearby.
"Ara, I didn't expect you to be such a cute little girl?"
Unohana Retsu looked at Rias floating in the air in astonishment and couldn't help but say.
"Waaah, so this is a Devil? An unseen creature and energy system!!"
Jibril wanted to fly over, a scythe subconsciously condensing in her hand, but she ended up crashing into an invisible light barrier.
Blinking, Jibril swung her scythe, trying to break the invisible protection, but unfortunately, she couldn't do it.
"It's better not to waste your energy."
Rias glanced at Jibril and said, "After all, this is a product that spans worlds, something even the Great Red couldn't detect. Even a Heavenly Strike won't shake it."
"I see, what a pity."
Jibril blinked, speaking with a face full of smiles, yet the power throughout her body underwent a qualitative change.
Her entire body converted into Spirit Corridors, continuously squeezing out power.
In just an instant, she condensed all her strength, and an object similar to a spear appeared in her hand.
After it crashed down, the invisible barrier didn't ripple in the slightest, while Jibril's spear of light vanished.
Following her launch of the Heavenly Strike, Jibril's body gradually shrank, eventually turning into a small child.
"Oops, I'm all out of power, ehehe~"
Jibril stuck out her tongue and acted cute.
"Ah, right, is Miss Rias like me? Are you out of power?"
Seeming to have thought of something, Jibril asked.
"My power is only this much~" Rias said troubledly. "Although I am a Devil, by comparison, I am just a 'living being.' Though I will eventually become a higher-order lifeform, I am indeed a new-generation Devil."
"Forgive my rudeness, but how old is Miss Rias this year?"
Unohana Retsu couldn't help but ask.
"Three years old."
Rias's tender voice rang out, leaving Unohana Retsu speechless.
She couldn't possibly raise a hand against such a moe, tiny little girl!!
"Eh!!" Jibril said in surprise. "In other words, Miss Rias can still grow?"
"Yes."
Rias nodded and said, "I am a new-generation Devil. In my world, there is an existence called 'Transcendents,' which means surpassing the 'limits' of one's race."
"In about two years, I'll be able to perfect the skills to burst forth with this power, and in less than ten years, I'll be able to fully reach this domain."
This was the rough calculation Rias had made before joining the Chat Group.
Even if there were discrepancies, it wouldn't be by much.
As for now, that's not necessarily the case~
"That's really wonderful then."
Jibril remarked with emotion.
"Yeah, my head still has room to increase in value, so don't go cutting it off easily~"
Rias joked.
"Understood, I'll be careful."
Jibril nodded seriously, looking quite cute.
"Are all your values so distorted?"
Unohana Retsu couldn't help but ask from the side.
"It's okay, after all, I'm a Devil."
Rias said calmly.
"After all, I'm a Flugel~"
Jibril also propped up the back of her head, floating in the air.
Although Jibril's power was exhausted, it didn't mean she was truly powerless.
Even this tiny body possessed power on par with Rias.
Such was the Flugel!
"Let's begin as well."
Rias chuckled softly.
"..."
At this moment, Unohana Retsu's desire to fight had vanished.
She really couldn't bring herself to bully a child.
"It seems I'm being looked down upon."
Seeing Unohana Retsu's reaction, Rias smiled, then her expression turned solemn.
A crimson radiance was released with her body as the center, and terrifying Destruction Magic Power pulsed through the air, causing it to let out bursts of wailing.
At the same time, sensing danger, Unohana Retsu hurriedly leaped backward.
That destructive magic power, along with the almost tangible pressure, made Unohana Retsu turn grave.
This power... it's so strong. It's similar to Spiritual Pressure, yet filled with violent energy.
Simply releasing her power gave her an alarming sense of crisis. That dense power made Unohana Retsu involuntarily become cautious.
"Now you should be able to get serious, right?"
Rias chuckled softly.
