"Can you tell me what your relationship is with Rias?"
Sona Sitri sat down next to Rias and asked, then added: "Of course, it's just my curiosity. If it's a secret, you don't have to say."
"No... if it's Sona-chan, it's perfectly fine~"
Rias smiled.
Sona-chan?
Sona Sitri hesitated for a moment.
Looking at her cheerful smile, Sona seemed to feel a faint sense of déjà vu.
Was she just naturally familiar, or did she really know her?
Perhaps she was some important figure who had held Sona when she was just born?
Sona wondered, then received an unexpected answer.
"Crimson is my symbol, but as for my true name—I am called Rias."
Rias smiled: "The Rias from a parallel world."
"A parallel world?!"
Sona was startled. After a few seconds of silence, she said hesitantly: "A Rias from a parallel world..."
It was indeed hard to believe.
After all, even for gods and devils, parallel worlds remained an unconfirmed concept.
Parallel worlds, Other Worlds—these were all existences based on theory.
Because of the existence of the Great Red in the Dimensional Gap, only a few people who had come into contact with Other Worlds knew about them.
For the younger generation of devils, this was still too early for them.
"If you're not sure, you can just treat it as role-playing for now,"
Rias laughed.
"No, I believe you."
Sona Sitri said: "If you are a Rias from a parallel world, the Underworld side will surely come to confirm it. It's likely that the silver-haired Queen of Annihilation will arrive. With that adult's ability, she will definitely not make a mistake."
"That's quite an unexpected answer."
Rias said: "But you've guessed one thing wrong, because even the Underworld cannot confirm my identity. However, I don't need others to confirm it anyway."
"But you can also treat me as a harmless young lady who's just here to play."
This time, Sona Sitri did not argue.
One thing was certain: Rias was indeed harmless to them.
After all, they were the sisters of the Satans.
It was a fact that the Underworld side would not leave uncertain factors around them.
Especially with an older sister who had a strong protective streak.
"Then can I know what I'm like in the parallel world?"
Sona Sitri asked curiously.
"Hmm... very cute, always following behind me and Serafall. Putting on fluffy Magical Girl outfits with a face full of shame, your shy expression was always so adorable."
"Wuhu, you were clearly a cute little Magical Girl when you were young, but you started to reject it when you grew up. Is this the rebellious phase?"
Hearing Rias's description, Sona Sitri's face turned red with a 'poof'.
She probably thought of herself putting on a fluffy Magical Girl costume and being forced to do all sorts of shameful poses.
"Is the Rias from the parallel world actually so mischievous?"
Sona Sitri forced herself to remain calm and said: "And isn't this something you've embellished? I don't remember following behind you when I was a child."
"How can liking beautiful things be considered mischievous?"
Rias said righteously: "And regardless of whether you followed me, based on your childhood personality, you definitely followed Serafall around even in the parallel world. That's for certain."
"Ugh... I can't argue with that,"
Sona Sitri said after thinking for a moment.
She really knew her well.
When Sona Sitri was a child, she was indeed very crisp and cute.
Even now, she still appeared to reject her sister on the surface, but in reality, she was just at a loss because her sister was too close.
In fact, she still liked and relied on Serafall.
In the original story, Serafall joined the Eternal War, and the Magical Girl drama that Serafall always updated was completed by Sona Sitri.
Even though it was incredibly embarrassing, she still did it, which was enough to show how close the two sisters were.
The atmosphere between the two was very good, and they chatted happily, though Rias's occasional teasing made Sona Sitri's face turn red.
Soon the school bell rang, and Sona Sitri took her leave.
Rias tossed the 'Absorption Line' in her hand to her and said: "I'll give this toy to you."
"What kind of Sacred Gear is this?"
Sona Sitri asked.
"The Absorption Line, it contains the soul of the Black Evil Dragon King."
Rias said: "I've already processed the Sacred Gear. It will react whenever it encounters a human with high compatibility. When that happens, just put the Sacred Gear into that 'human's' body, and it will make her a Sacred Gear Wielder."
She, restricted to females.
To prevent the plot from taking a turn and having the Absorption Line return to Saji Genshirou's body, Rias had placed a restriction.
Although the possibility was not high, 'accident prevention' still had to be done.
Moreover, for a male of this age, it would be hard to ignore Sona Sitri's charm when being in close proximity.
So by simply restricting it to females, that incredibly boring possibility would become zero.
"Isn't this too precious?"
Sona Sitri said in surprise.
The Absorption Line was an extremely powerful Sacred Gear. If it contained the complete soul of the Black Evil Dragon King, it would likely possess power comparable to a Sacred Gear level.
Even if it was only a quarter, it was still quite a remarkable power.
"It's just a toy, it's nothing to me."
Rias waved her hand.
Hearing this, Sona Sitri also nodded.
Although it was considered precious, to her it was just precious, not something completely unattainable.
So after saying thanks, Sona Sitri accepted it.
After all, as a young High-Class Devil, she needed power in various aspects.
Especially since she wanted to realize her dream, power was an absolutely indispensable thing.
As for the Rias of this world also needing power... Sona Sitri had no doubts about that after seeing Rias's special training.
Furthermore, a powerful Sacred Gear was just potential. Unless the person was very strong to begin with, the ability to unleash the Sacred Gear's power still depended on the user themselves.
And what Rias needed was existing powerful strength, which... probably wouldn't be a problem.
If the Rias of this world awakened her demonic power, Riser Phenex would truly be nothing.
Given their relationship, they had already communicated not long after the Rias of this world finished her training.
It was precisely because she was curious about Rias that Sona Sitri rushed over and initiated a conversation after sensing the fluctuations of the Sacred Gear.
