No one can stop him

Either Xenovia or Riser didn't stop, and they kept having sex for several hours.

This forbidden knowledge made her unable to get away from him, and she wished to learn this knowledge from him. 

The school?

Sona's peerage members?

If possible, she wished to be with him all the time instead of doing all of that.

Nevertheless, he was surprised by her stamina, but then again, as the holder of the Durandal and Excalibur Destruction, it was natural for her stamina to be above the majority of people.

Her stamina was probably even stronger than most of the devils, showing how exceptional she was as an individual.

Yet, as expected, it was her first time, so soon, she slept on his chest from exhaustion.

Frankly, her actions were quite reckless.

She was like a Level 1 character who decided to face the last boss right away.

Besides an instant demise and meaningless struggle, she could only fall under his arms.

Nevertheless, as the two were having love, Ravel, who was accompanied by Yubelluna and Mihae to set up a "Rating Game" for him, quickly became the center of everyone.

Everyone had been waiting for his answer, so when they heard that he would have a "Rating Game," they knew that he didn't intend to apologize and decided to charge forward without caring about Sirzech.

Frankly, everyone was helpless, and they wished for Ravel to talk to Riser to give up, asking him to apologize to Sirzech, but she didn't heed their words and just set up a return match for Riser so everyone could see the power of her older brother.

As for asking Riser?

How could they be?

They had seen how stubborn Riser was.

In his video fight against Kokabiel, Vali, Azazel, and Sirzech, they could see that even if Riser died in his fight, he kept storming forward, radiating his blazing fire, ignoring all the consequences.

If Riser was still as weak as before, they might keep cussing him, telling him to give up, but he was strong.

Moreover, they could tell that this wasn't his limit.

There might be a chance that Riser might be able to compete with Sirzech in the future.

Making him angry definitely wasn't an option.

Even Sirzech's clique didn't dare to be so harsh on Riser. They might be famous politicians, and some of them held important positions in the government, but Riser had the support of the richest family in the Underworld and one of the Four Maou, Serafall Leviathan, along with the Sitri House. Moreover, he was the son-in-law of the heir of the Sitri Clan and the direct descendants of the Phenex House.

Having a conflict with him and being remembered as an enemy by him definitely wasn't an option.

No one wished to have a full-blown conflict where it was impossible for them to recover their relationship to their previous one.

So, in the end, they could only ask Serafall, hoping she could do something as they knew she should be able to do something.

As for Sona? No one asked her opinion, as in the eyes of those devils, she was still a little girl.

However, Serafall didn't say anything and just let him have a "Rating Game" without giving a single.

While everyone was helpless, there was nothing that they could do.

Yet, there was no doubt that his "Rating Game" wouldn't be so easy.

This wouldn't be an easy game where he could show all the devils of his overwhelming, so no one could stop his promotion as the "Ultimate Class Devil."

Instead, it would be a test.

If he won, then no one could stop him.

So what if he loses?

There was no doubt that his name would be stained even further.

Naturally, Sirzech heard the news Riser wished to have a "Rating Game" was heard by Sirzech immediately. It was a rare chance for him to have his little revenge. It might be impossible for him to attack him again as he didn't want to have a conflict with Riser's support.

Yet, he also felt helpless, thinking that Riser was too stubborn.

"If that's your wish, then I will play along."

Nevertheless, Sirzech smiled as he thought about how Riser's embarrassing and shameful appearance would be shown to the public. Using his contacts, he started his plan, and no one could stop it anymore.

---

"So-chan."

Serafall forcefully entered her little sister's room, breaking her door without hesitation.

"...."

Sona wanted to say something, but she was too weak to say anything.

After he told her not to follow him, Sona didn't go to school and stayed in the Underworld all the time in case she received a call from Riser so she could meet him immediately. However, so many days had passed, yet she didn't receive a call from him, so she holed up in her room all the time.

While she didn't understand at first, Serafall told her why he was angry, and she also understood why he told her not to follow him.

During that fight at the Kuoh Academy, she wished for him to tend his wounds as soon as possible and thought that it was the best course of action; there was no doubt that action hurt him as she didn't trust him.

She was different from him. He could trust her unconditionally, believing that she could make the "Rating Game" school for the lower-class devil. Yet, she selfishly thought what was the best for him, thinking that it was the best for him, yet in his eyes, she probably had betrayed him.

In that critical moment, she, who was his wife, like others, didn't believe him.

She regretted it, but at the same time, she didn't know what to do, only as it was her first time to fall in love, yet she messed it up.

"Riser-chan had decided to fight, you know? Are you just going to hole up in your room?" Serafall asked.

"...fight?"

"Un." Serafall nodded. "He is going to have his "Rating Game" soon. There is no doubt that Sirzech-chan is going to mess up his match."

"..." Sona.

"So, what are you going to do?"

"...I am going."

Sona had messed up before, but now, there was no way she was going to mess up again.

Even if his opponent was Sirzech Lucifer, so what?

Anyway, her husband dared to kill Sirzech before.

Moreover, while she was helpless, there was nothing that she could do.

Lastly, between Sirzech and her husband, it was obvious who she should choose, right?

"That's good~!" Serafall was happy since Sona had returned, but what about her?

What should she do?

---

"Rias, I heard that he was going to have his "Rating Game" soon."

"Then, let's meet him."

Rias didn't hesitate.

"...are you serious?" Akeno looked at Rias in a complicated mood.

Frankly, she wished to meet him, but when she thought about his relationship with the older brother of her master, she hesitated since she knew she had become nothing but a burden for him.

Moreover, she could see how much hatred he had toward the fallen angel, especially when they had troubled him so much.

When Akeno thought about her identity, she couldn't help but loathe herself and wonder how fate loved to play a joke on her so much.

"I am."

From that day on, Rias was unable to erase her thoughts about him. She knew that it was wrong, especially when he was the enemy of her older brother, yet... yet... for someone who dared to fight her older brother even at the expense of his life... There was no doubt that there was no guy other than him that could enter her eyes.

Even if the world wished for him to fall, bowing his head, and no one supported him, Riser decided to fight.

There was no doubt that at this moment, he was at the lowest moment of his life, and when she came, becoming his support and his only light, she knew that he was going to fall.

This time, it will be different.

There was no way Sona could stop her.

Rias was going to make him fall for her.

Yet, strangely enough, Akeno hoped for Rias to be successful.

If her master could seduce Riser, then would there be a need for them to hide their relationship?

As for his conflict with Sirzech? They didn't care, as love made them blind. They only wanted to be with him.

Moreover, as Sirzech had become a Lucifer, he was no longer a devil from the Gremory, at least in public. It was also the reason why he could no longer become the heir of the Gremory House, changing his father to the Lord of Gremory and leaving the heir position to Rias while changing his name from Gremory to Lucifer.

For the first time, a master and a servant had the same thought as they wished to meet him.

Yet Akeno was also worried, wondering whether her existence would become anything but a burden for him.

Nevertheless, his return match was naturally heard by everyone, and no one was going to miss it, especially when the name of his opponent was announced.

Yet, Riser was still oblivious to all the commotion caused by him.

Instead, he wondered why Xenovia could give him such rich rewards.
