DxD: The Holy Knight!

"Here are your evil pieces."

"Hmph!"

Without any hesitation, Rias snatched her pieces from Yasuhiro.

"If I had known it would turn out this way, I wouldn't have given you my pieces."

"Do you really think you could keep the pieces if I wanted to snatch it? Even with your strength combined with the rest of kuoh, who could stop me?"

Yasuhiro's blunt words struck a nerve with Rias.

"Do you really think you are invincible and can do whatever you want?" Rias detested his arrogance.

"On a global scale, I wouldn't call myself invincible. But within kuoh, my current strength certainly qualifies me as someone who can do whatever I want. You should know that better than anyone, shouldn't you?"

"You..."

Seeing Rias gritting her teeth in anger, Akeno secretly shook her head. There were probably few people in the entire kuoh academy who could verbally defeat Yasuhiro.

Even she was powerless...

"Huh, what is this...?" Sona, who had just taken her pieces, sensed a difference.

"What happened to Sona? Did he tamper with the evil pieces?" Rias looked at Sona with concern and asked.

"No, it's just that I sensed some unknown changes brought about by the pieces, even a slight increase in demonic power."

"The increase in demonic power is secondary. The most important thing is that the improved pieces will provide you and your peerage with an overall enhancement during battles," Yasuhiro explained patiently.

"You actually improved our pieces!" Rias and Sona looked at Yasuhiro in surprise.

His ability to not only break the seal on the evil pieces but also thoroughly understand the knowledge contained within it and create brave saint cards undoubtedly suggested that he has unparalleled talent in this area.

Sona was both happy and worried. Looking at Yasuhiro, she knew that the so called improvements must have originated from heaven's research.

Although heaven had not created a reincarnation technology for angels after so many years of research, its technological breakthroughs in other areas were no less than those of the devils, and in some aspects they were even better.

Yasuhiro had clearly modified their pieces without the consent of heaven and even the church.

From the perspective of a servant of God, Yasuhiro had committed treason in every respect.

"Don't worry. They won't punish me for such small matters." Yasuhiro was speaking the truth. In terms of importance, he was one of the most important figures in heaven.

His voice was above that of the Four great seraphs in certain decisions.

What Yasuhiro was thinking was unknown to Rias, Sona and the others.

They thought that the compensation Yasuhiro gave to improve Sona and Rias's evil pieces would be discovered by heaven, and thus result in severe punishment for him.

"This is for you."

"What is it?" Sona took the parchment from Yasuhiro's hand and asked curiously.

The parchment in Sona's hand was somewhat similar to the one Yasuhiro had previously used to transmit info to heaven.

However, this parchment did not possess the transmission function of the previous one, it was merely an ordinary parchment capable of recording holy texts.

"During the creation of the cards, we researched and developed the framework and implementation theory for some of the card's combat tactics, which are essentially the optimizations to your evil pieces."

Sona and Rias looked at Yasuhiro with some surprise.

They did not yet fully understand the advantages of their improved pieces.

However, the combat tactics developed by heaven during their research on the brave saint cards could be considered as one of their core technologies.

The fact that Yasuhiro was able to take out such a thing indirectly demonstrated his high status.

"Yasuhiro, you have taught us the battle tactics, you..."

"Don't worry. As I've already said, they won't blame me for such small matters. Besides, this info is my compensation for stealing your technology."

Moreover, the combat tactics were developed for angels, as for how devils can use it...

That's not his concern.

"Thanks..."

Sona sighed softly and accepted it. After all, this was not a decision she could make alone, it concerned the diplomatic issues of the both parties.

Rias's anger towards Yasuhiro subsided considerably. His previous improvement of their pieces was a form of compensation.

Now, giving them these tactics, was his compensation to the underworld.

In this way, if Sona were to hand over these skills to the upper echelons of the underworld, the punishment she'd receive might be greatly reduced, perhaps resulting in at most a verbal warning.
