The next day—
Serafall woke up from her slumber.
Pillowed against Rias's vast bosom, she felt as if she were in the middle of a great ocean, a feeling of being completely embraced welling up in her heart.
"Mm... It's already morning... I have to work hard."
Serafall spoke groggily, nuzzling against Rias's chest, only then realizing something was off.
The size was wrong; this wasn't Sona-chan's size!
Opening her eyes, Serafall looked at Rias's sleeping face, and her breath hitched slightly.
It seemed she had been sweet-talked yesterday and then thoroughly toyed with by Rias.
This girl's technique was simply too good; it was hard to imagine how many scenes of romantic jealousy she had navigated.
She had asked, and then Serafall received a rather subtle answer from Rias.
A significant portion of Rias's techniques had been practiced on the Serafall of the parallel world!
As for how many years that process lasted... it made Serafall suspect that the version of herself in the Other World might be a hentai who liked little girls.
But on second thought, that didn't seem right either. With Serafall's capabilities, she could only be the submissive one in front of Rias. Could it be that the version of herself in the other world was the same?
Thinking this way, she indulged in the comfortable ocean until the next day.
Who am I, where am I, and what did I do yesterday?
Thinking carefully, it should be: what was done to me yesterday?
"Wuwu, I'm never going to get married now."
Serafall sobbed softly.
"Then just marry me."
Rias said playfully.
"You're awake."
Serafall glanced at Rias and whispered.
"Yeah."
Rias's finger lightly brushed against the inside of her thigh, making her shudder as her entire face flushed crimson.
"The me in the parallel world... was like this too?"
Serafall lay on top of Rias, her body stiff and unmoving.
"Yeah, just like you, she looks like a dominant on the surface, but she's actually very fun to bully."
Rias laughed. "You sisters are both equally soft."
"The Sona-chan of that world too...?"
Serafall asked in surprise.
"Hmph hmph." Rias hummed proudly, then moved her small hand up to rub her belly.
That slow caress sent a wave of heat through her abdomen, making her feel a bit lewd.
To think that when she said she slept on the left and Sona on the right, it was in that sense... Is this what a Magical Girl is?
I'm down for it.
"Speaking of which, today Sona and the other me are going to break off the engagement, right?"
Rias remembered this matter.
"Mhm, it's time to get rid of that annoying engagement!"
Hearing this, Serafall's eyes turned fierce, as if flames were burning within them.
"If anyone wants to marry my Sona-chan, they have to beat me first!"
"Sona-chan is mine!"
"Then the men who like Sona are truly ill-fated," Rias laughed.
"Those trash aren't worthy of Sona at all; only I can stay by Sona-chan's side forever!"
Serafall said excitedly.
Looking at her like this, Rias smiled. "Then what about me?"
"Ugh... well..."
Serafall hesitated.
In theory, even a woman shouldn't be allowed to take Sona's affection away from her.
But with the Rias in front of her, she felt it was fine.
"I can share a little bit of Sona's love with you, but only a little bit, okay?"
Serafall said conflictedly.
"Fufu, that's very kind of you."
Rias laughed, then pulled Serafall's head toward her, burying her face in her bosom.
Serafall made a symbolic struggle but couldn't break free.
Scenting the fragrance on Rias's body, Serafall's face turned red, and before long, her breathing became heavy.
Rias's body always carried a fragrance that the Rias of this world did not possess.
Because it could make Serafall excited, as if she were truly facing a lover.
Just by feeling her skin, Serafall gained a dual sense of physical and spiritual satisfaction.
After a long time, the two finally got out of bed.
After having breakfast, they prepared to go watch the battle.
There were two Rating Games in total, using the same venue.
"Sister."
After arriving at the Rating Game venue in the Underworld, Sona felt relieved upon seeing Serafall.
Sona relied heavily on Serafall, and naturally, she had Serafall's support for breaking off the engagement.
If she could see Serafall before the battle and know she was always supporting her from behind, Sona would have great motivation.
"It seems she is the master chosen by the Sacred Gear."
Rias looked toward a woman.
Not all of Sona's peerage were Sacred Gear Wielders.
Compared to the Rias of this world, Sona was not picky when collecting her peerage; as long as they had certain potential and value, she would take them in.
In comparison, the Rias of this world had higher standards.
In fact, the potential of Rias and Sona did differ significantly.
Rias's magic trait was Power of Destruction, while Sona's was water, so Sona later became a strategic Ultimate-class Devil.
"Yes, she is my trump card for this battle."
Sona said, looking at Rias.
"Hello, I am Kiryu Aika."
Kiryu Aika bowed and said.
Rias remembered.
Kiryu Aika, this rather perverted glasses girl.
It was said she could figure out a man's shape and size just by looking.
Of course, the same would naturally apply to women.
Rias remembered that she had a talent for learning magic.
However, in such a short time, could Kiryu Aika be qualified for the position of a trump card?
Rias looked at Sona.
"I am more skilled in precise strategy, rather than the type to suppress others with brute force," Sona said. "Everyone has their role. Even if Aika cannot fully unleash the power of her Sacred Gear right now, there will always be things she can do."
"That's a statement that truly fits your personality," Rias laughed.
Sona seemed cold, but she actually made people feel more at ease.
"Good luck, Sona." Soon the Rating Game began, and before entering the field, the Rias of this world couldn't help but cheer for her friend.
"Yeah, you too."
Sona paused, then spoke softly.
They entered the Rating Game field, and then the game began.
Despite being a High-Class Devil, Sona's fiancé was a piece of trash.
This was because Serafall of the Sitri Family had become a Satan, leaving Sona as the only successor.
Since she was the successor, she had to hold the initiative regardless of family status or power.
As for using any foul methods in the Rating Game, Serafall could directly teach him a lesson.
Other Satans might have some reservations, but Serafall was someone who could even go to war with Heaven for the sake of her sister.
Even if it was just a saying, she was definitely capable of doing it.
The result was not unexpected; with Sona's stable performance, she defeated her opponent almost in a landslide.
And next, it was Rias's turn.
