"Akira-kun, you... what did you say?" Sona couldn't believe it. She never thought she would be the one to have a marriage proposal revoked!

"Sona, I said I want to dissolve our engagement," Akira repeated.

"Why... why?"

"Because I don't want to marry into the Sitri family. Even if I were to marry you, Sona, I would want you to marry into my family, not the other way around," Akira explained honestly.

"So that's how it is..."

Sona let out a sigh of relief.

It turned out that Akira wasn't rejecting her. He simply wanted to switch their roles in the engagement and take the dominant position.

...

"Akira-kun, you do know your status, right?"

"Yes, I am the nominal heir of the former Leviathan bloodline."

"Akira-kun, besides that, you should also know my status, correct?"

"Yes, you are the younger sister of the current Leviathan and the sole heir to the Sitri family."

"Akira-kun, knowing all this, you should understand—the Underworld would never allow the former Leviathan to take the dominant position in a marriage with the blood relative of the current Leviathan."

"The Sitri family would also never agree to let their only heir marry into another family!"

Seeing Sona's serious expression, Akira sighed helplessly.

"So, if I want to take the dominant position, I'll have to change my marriage partner?"

"Huh?!"

"Wait, Akira-kun, that's not what I meant. I just..." Sona was suddenly flustered.

[I just want you to accept your status and marry me as it is?]

Such words sounded too arrogant and selfish.

Yet, this was indeed Sona's first thought.

Realizing she had such thoughts, Sona's pride as a high-class demon was shattered.

So this was how it felt to be the weaker party facing the stronger one?

In the past, Akira had been in this position while interacting with her, and it was under such circumstances that he had strived to become stronger.

The situation had only reversed for a day or two, and she already couldn't stand it.

But Akira had endured it for over a decade.

No wonder the former Akira had looked at her with the eyes of a rival.

...

"I know, Sona. You just don't want to break off our engagement."

"In truth, I also like you a lot," Akira explained.

"If you like me, then why do you still want to dissolve the engagement?" Sona pursed her lips, confused.

"Why?"

"Because I don't want to be bound by the current system of the Underworld."

"In this regard, Sona, you and I are the same. If you want to realize your dream of establishing a school in the Underworld, you must change the current system."

"So, from this perspective, we are comrades fighting against the existing system of the Underworld."

"If we're comrades, then why do we still need to dissolve the engagement?" Sona was still puzzled.

"Why, you ask..."

"Because the two of us alone aren't enough. We need more allies."

"Only by dissolving my engagement with you can I participate in Rias's engagement and bring her to our side."

"Rias?"

"You mean... you want to become Rias's fiancé?" Sona felt her heart tighten even more.

"That's right."

"There's no other way. If we want to change the Underworld's system, our current strength is too weak."

Akira believed that his engagement with Rias was of great significance.

Rias and Sona were fundamentally different.

He couldn't be stronger than Sona because that would represent the former Leviathan's resurgence over the current Leviathan.

However, he could be stronger than Rias.

Since his relationship with Rias would be seen as "free love," the stronger he became, the more pleased others would be.

Once the news of his engagement with Rias spread, he would be able to use the "Boosted Gear" without any reservations.

This way, Sirzechs would be seen as his backer.

Both Sirzechs and other demons would refrain from targeting him due to his engagement with Rias.

Thus, he would have the right to openly build his own forces and prepare for his future independence.

So, even if it was just a formality, Akira had to go through with the engagement with Rias.

...

"I..."

Sona wanted to say something but found herself at a loss for words.

Akira was right.

In their current state, trying to change the Underworld's system was nothing short of a pipe dream. They needed to unite more forces.

"Since the matter is settled, I'll take my leave now. Rias is also waiting to discuss the engagement with me."

Akira stood up, ready to leave.

"Sona, no matter what, I truly do like you."

"When I have enough strength, I will definitely propose to the Sitri family."

With those words, Akira opened the student council room door and left.

Sona pondered over Akira's words, her rose-colored eyes widening in realization.

"Akira-kun! Do you realize what your words imply?!"

Sona sought final confirmation.

Akira marrying into her family and her marrying into his were two entirely different concepts!

"I know what it means."

"If the current family head is unwilling to let their daughter marry out, and someone wants to forcibly take away the only pure-blooded heir, they must defeat every remaining member of that family."

"That's right, it means..." Sona's expression grew serious.

"It means I have to defeat Serafall."

"Akira-kun, what do you think your chances are of defeating Serafall-sama?"

"One thousand percent."

"Huh? Akira-kun, do you really think you can defeat Serafall-sama?" She was one of the current Four Great Satans!

"Sona, if you don't even dare to have the ambition to defeat Serafall, you might as well give up on your dreams now."

"That's all."

Akira turned to leave, closing the student council room door behind him.

Thud.

Sona collapsed onto the sofa, her eyes filled with confusion.

Originally, she had thought that Akira wasn't worthy of her.

Now, it seemed that she wasn't worthy of Akira.

Not only did she fall short in terms of intellect and strength, but she also lacked the determination and ambition that Akira possessed.

Such a her... truly didn't have the right to demand that Akira marry into her family.

...

Haaa...

Taking deep breaths, Sona thought for a long time.

Finally, she made a risky decision.

"Tsubaki, come with me."

"Didn't we recently find a powerful Sacred Gear user? I plan to transplant that Sacred Gear into myself."

"A pure-blooded demon using a Sacred Gear would undoubtedly be stronger than a reincarnated demon using one."

Due to the changes in the story, transplanting Sacred Gears was no longer exclusive to the Fallen Angels.

"Alright..."

Tsubaki nodded.

She had wanted to remind Sona about the "Sacred Gear compatibility" issue, but she knew Sona had already considered it.

"My attribute is water, and that Sacred Gear is dragon-based. Dragons control clouds and rain, so the compatibility shouldn't be too low."

"Only by obtaining that Sacred Gear... will I have the qualifications to stand on equal footing with Akira-kun and be able to help him."

Although Sona hoped that Akira would truly defeat Serafall and come to marry her, she wasn't the type to simply wait for a man to grow stronger while she cheered from the sidelines.

She too... wanted to do what she could!
